Brain Changes
Ponder what would happen to the neural network if there were
disruptions at different times during development. Depending
on what is happening at a specific time, progress might be
significantly slowed. In addition, if brain development is
disrupted at certain times, progress might also end and
everything that depends on the formation of that area or
structure will be altered. The crucial developmental times are
called critical periods of brain development. Let's look at the
importance of these developmental periods.
There are periods during brain development when neurons are
more vulnerable to being directly harmed by introduced
chemicals or stressors. During these times, development might
be significantly and irrevocably harmed. One well-known
example of an environmental stressor is alcohol. Heavy alcohol
consumption during pregnancy might result in the child being
born with fetal alcohol syndrome (FAS). Due to cell alterations,
children with FAS have distinctive facial abnormalities, heart
defects, motor problems, and cognitive deficits.
How can the environment alter brain development? This is
possible because of the neuron's ability to adjust its morphology
and neurochemistry. The neuron's capacity for adaptation is
called neuroplasticity. Environmentally induced neuroplasticity
takes place early in the life of the fetus as the fetus is affected
not only by what the mother does and eats but also the
environment in which the mother lives.
When the brain has been injured due to an ischemic stroke, for
example, some of the brain tissue is lost and there is a
corresponding change in behavior. Note that ischemia occurs
when the blood flow to an area of the brain is interrupted, and
during that time, the tissue beyond the blocked arterial branch
is starved of oxygen and glucose.Additional Materials

Ischemic Stroke
An ischemic stroke is caused when blood vessels are blocked.
The tissue that is no longer receiving
blood flow dies within seconds.

This person has suffered an ischemic stroke in the left temporal-
frontal region of the brain and will
have trouble speaking and moving the right side of his face and
arm.
This is the area of tissue loss as a result of the stroke.
Neuroplasticity will enable this person’s brain to
reorganize to compensate for damage. He may regain most of
his preinjury functions as other
neurons change their morphology and functional ability.
Myers-Briggs type inventory
type ESTJ
PERSONALITY (“THE EXECUTIVE”)
Summary
ESTJs are representatives of tradition and order, utilizing their
understanding of what is right, wrong and socially acceptable to
bring families and communities together. Embracing the values
of honesty, dedication and dignity, people with the ESTJ
personality type are valued for their clear advice and guidance,
and they happily lead the way on difficult paths. Taking pride in
bringing people together, ESTJs often take on roles as
community organizers, working hard to bring everyone together
in celebration of cherished local events, or in defense of the
traditional values that hold families and communities together.
ESTJs are aware of their surroundings and live in a world of
clear, verifiable facts – the surety of their knowledge means that
even against heavy resistance, they stick to their principles and
push an unclouded vision of what is and is not acceptable. Their
opinions aren't just empty talk either, as ESTJs are more than
willing to dive into the most challenging projects, improving
action plans and sorting details along the way, making even the
most complicated tasks seem easy and approachable.
However, ESTJs don't work alone, and they expect their
reliability and work ethic to be reciprocated – people with this
personality type meet their promises, and if partners or
subordinates jeopardize them through incompetence or laziness,
or worse still, dishonesty, they do not hesitate to show their
wrath. This can earn them a reputation for inflexibility, a trait
shared by all Sentinels (SJ), but it's not because ESTJs are
arbitrarily stubborn, but because they truly believe that these
values are what make society work.Strengths
· Dedicated – Seeing things to completion borders on an ethical
obligation for ESTJs. Tasks aren't simply abandoned because
they've become difficult or boring – people with the ESTJ
personality type take them up when they are the right thing to
do, and they will be finished so long as they remain the right
thing to do.
· Strong-willed – A strong will makes this dedication possible,
and ESTJs don't give up their beliefs because of simple
opposition. ESTJs defend their ideas and principles relentlessly,
and must be proven clearly and conclusively wrong for their
stance to budge.
· Direct and Honest – ESTJs trust facts far more than abstract
ideas or opinions. Straightforward statements and information
are king, and ESTJ personalities return the honesty (whether it's
wanted or not).
· Loyal, Patient and Reliable – ESTJs work to exemplify
truthfulness and reliability, considering stability and security
very important. When ESTJs say they'll do something, they keep
their word, making them very responsible members of their
families, companies and communities.
· Enjoy Creating Order – Chaos makes things unpredictable, and
unpredictable things can't be trusted when they are needed most
– with this in mind, ESTJs strive to create order and security in
their environments by establishing rules, structures and clear
roles.
· Excellent Organizers – This commitment to truth and clear
standards makes ESTJs capable and confident leaders. People
with this personality type have no problem distributing tasks
and responsibilities to others fairly and objectively, making
them excellent administrators.Weaknesses
· Inflexible and Stubborn – The problem with being so fixated
on what works is that ESTJs too often dismiss what might work
better. Everything is opinion until proven, and ESTJ
personalities are reluctant to trust an opinion long enough for it
to have that chance.
· Uncomfortable with Unconventional Situations – ESTJs are
strong adherents to tradition and when suddenly forced to try
un-vetted solutions, they become uncomfortable and stressed.
New ideas suggest that their methods weren't good enough, and
abandoning what has always worked before in favor of
something that may yet fail risks their image of reliability.
· Judgmental – ESTJs have strong convictions about what is
right, wrong, and socially acceptable. ESTJs' compulsion to
create order often extends to all things and everyone, ignoring
the possibility that there are two right ways to get things done.
ESTJs do not hesitate to let these "deviants" know what they
think, considering it their duty to set things right.
· Too Focused on Social Status – ESTJs take pride in the
respect of their friends, colleagues and community and while
difficult to admit, are very concerned with public opinion.
ESTJs (especially Turbulent ones) can get so caught up in
meeting others' expectations that they fail to address their own
needs.
· Difficult to Relax – This need for respect fosters a need to
maintain their dignity, which can make it difficult to cut loose
and relax for risk of looking the fool, even in good fun.
· Difficulty Expressing Emotion – This is all evidence of ESTJs'
greatest weakness: expressing emotions and feeling empathy.
People with the ESTJ personality type get so caught up in the
facts and most effective methods that they forget to think of
what makes others happy, or of their sensitivity. A detour can
be breathtakingly beautiful, a joy for the family, but ESTJs may
only see the consequence of arriving at their destination an hour
late, hurting their loved ones by rejecting the notion too
harshly.
CAREERS
ESTJs' career paths are often as clear and straightforward as
they are themselves. Though there are many directions they can
choose to go, people with the ESTJ personality type almost
always end up in situations where they have the opportunity to
exercise their affinity for organization, structure, and follow -
through. Providing further focus, ESTJs share a profound
respect for tradition, stability and security, qualities which lend
themselves well to progressing along clear paths to increased
responsibility and dependability.
ESTJs' sense of loyalty results in them staying with a single
employer as long as possible, and their reverence for
established institutions often leads to work with well-respected
organizations. Law enforcement, military service, hospitals and
prominent legal firms are all able to recognize ESTJs' long
years of service.
ESTJs are the image of the model citizen, and they strive to
maintain this ideal throughout their careers. This helps them
move forward into management as well – people with this
personality type have many traits inherent to leadership,
something that is often recognized regardless of their chosen
industry. From the genuine enjoyment ESTJs feel in organizing
other people to their knack for clearly expressing their
principles, values and expectations, ESTJs are extremely
effective managers.
Also fearsome leaders, ESTJs loathe disorganization, ineptitude,
laziness and especially dishonesty, and when these values are
crossed, ESTJ personalities do not hesitate to let their
disapproval show. So long as everyone plays by the rules,
ESTJs are incredibly efficient, their love of structure and
thoroughness leaving a record of accurate, complete work that
is on time and on budget. ESTJs are natural auditors, financial
officers and business administrators, and any such and similar
roles are excellent choices for them.
Hard work and self-motivation are also strong ESTJ principles,
which makes them excellent sales representatives, whether in
basic retail positions, part of office teams, or as independent
agents. People with the ESTJ personality type stick to projects
until they're finished, big or small, and are organized enough to
make any necessary paperwork a mere minor inconvenience to
their clients, rather than some baffling ordeal. These qualities
combine to make the clear steps in advancement that ESTJs
require in order to maintain a sense of accomplishment not just
viable, but almost inevitable.
WORKPLACE Habits
ESTJs show clear and consistent tendencies, and these are
especially visible in the workplace. Whether subordinates,
among colleagues or as managers, people with the ESTJ
personality type create order, follow the rules, and work to
ensure that their work and the work of those around them is
completed to the highest standards. Cutting corners and shirking
responsibility are the quickest ways to lose ESTJs' respect.
ESTJ Subordinates
ESTJs are hard-working and do things by the book. Though
sometimes stubborn and inflexible, especially when presented
with ideas that haven't been fully developed, ESTJ personalities
are open to new methods that can be demonstrated to be better.
However ESTJs are unlikely to do much experimenting on their
own – adhering to stated responsibilities and fulfilling their
duties is their primary concern.
ESTJs are also well-known for their loyalty and dedication, but
in some ways this is contingent on their respect. People with
this personality type are willing to voice their opinions,
especially in deciding what is and is not acceptable – if
provided with sensible responses that address their concerns,
they are often satisfied with that. If ESTJs view their managers
as illogical, dishonest or cowardly in their methods, they can be
uncomfortably honest, if still calm and level, in voicing their
opinions on that as well.
ESTJ Colleagues
ESTJs enjoy the hustle and bustle of well-organized workplaces.
Honest, friendly and down-to-earth, ESTJ personalities are great
networkers who enjoy connecting with others to get things done.
Abusing this for advancement is unlikely, and is in fact
something ESTJs frown upon. Shortcuts are irresponsible, and
people with the ESTJ personality type lose respect quickly for
those who try to push forward by showing off or promoting bold
but risky ideas, making relationships with more inspiration-
oriented colleagues a challenge.
ESTJs like to feel like they are a part of the team, and a part of
the greater organization that they work for. To make sure this
happens, ESTJs are nearly always willing to accept criticism
that can help to improve their effectiveness, and always keep an
eye on their surroundings to make sure they and their team
deliver the results that are expected of them.
ESTJ Managers
ESTJs take genuine pleasure in organizing others into effective
teams, and as managers they have no better opportunity to do
so. While sometimes overbearing, even micromanaging, ESTJs'
strong wills also serve to defend their teams and principles
against diversions and cutbacks, regardless of who brings them.
Laziness and bad work ethic are not tolerated by ESTJs under
any circumstances.
ESTJs project natural authority, but they sometimes expect this
authority to be abided unconditionally, resisting change and
demanding that things be done by the book. Whether ESTJs'
own book or the existing rules and traditions are used is subject
to circumstances, but they do tend to rest on the security of
tradition and precedent. Regardless, ESTJs' expectations are
clearly expressed, leaving little room or tolerance for deviation
from the agenda.
CONCLUSION
Few personality types are as practical and strong-willed as
ESTJs. Known for their reliability and administrative skills,
ESTJs are good at creating and maintaining a secure and stable
environment for themselves and their loved ones. ESTJs'
dedication is invaluable in many areas, including their own
personal growth.
Yet ESTJs can be easily tripped up in areas where their rational
and practical approach is more of a liability than an asset.
Whether it is finding (or keeping) a partner, learning to relax or
improvise, reaching dazzling heights on the career ladder, or
managing their workload, ESTJs need to put in a conscious
effort to develop their weaker traits and additional skills.
What you have read so far is just an introduction into the
complex concept that is the ESTJ personality type. You may
have muttered to yourself, "wow, this is so accurate it's a little
creepy" or "finally, someone understands me!" You may have
even asked "how do they know more about me than the people
I'm closest to?"
This is not a trick. You felt understood because you were.
We've studied how ESTJs think and what they need to reach
their full potential. And no, we did not spy on you – many of
the challenges you've faced and will face in the future have
been overcome by other ESTJs. You simply need to learn how
they succeeded.
But in order to do that, you need to have a plan, a personal
roadmap. The best car in the world will not take you to the right
place if you do not know where you want to go. We have told
you how ESTJs tend to behave in certain circumstances and
what their key strengths and weaknesses are. Now we need to go
much deeper into your personality type and answer "why?",
"how?" and "what if?"
This knowledge is only the beginning of a lifelong journey. Are
you ready to learn why ESTJs act in the way they do? What
motivates and inspires you? What you are afraid of and what
you secretly dream about? How you can unlock your true,
exceptional potential?
Our premium profiles provide a roadmap towards a happier,
more successful, and more versatile YOU! They are not for
everyone though – you need to be willing and able to challenge
yourself, to go beyond the obvious, to imagine and follow your
own path instead of just going with the flow. If you want to take
the reins into your own hands, we are here to help you.

Neuroanatomy
The human brain is a complex structure responsible for
expressing innate abilities and retaining learned information.
Our brain holds the memories and expressions that make up our
personality; it is the physical configuration of who we are.
The cerebellum is part of the hindbrain—one of the major
divisions of the brain. Along with the cerebellum, the hindbrain
contains the medulla and pons; both structures can be found in
the brain stem—a complex projection that mediates many basic
and life-sustaining bodily processes.
The thalamus is much like a relay station for signals in the
brain; the hypothalamus is associated with regulation of
hormones and the drive system. The hippocampus is related to
memory and the basal ganglia are related to expression and
movement.
The four ventricles—cavities in the brain that contain the
cerebral spinal fluid—sit in the middle of the brain. This fluid
serves at least two purposes—it helps remove waste from the
brain and provides some cushioning during sudden movements
and impacts.
The CNS is one of the two major divisions of the body; the
other division is called the peripheral nervous system (PNS).
The long axonal projections of the spinal cord link the brain and
the PNS. The PNS has two divisions—somatic and autonomic.
The somatic system conveys incoming sensory information to
the CNS and is responsible for motor messages that are sent
from the CNS to the PNS. When you reach out to touch a key on
your keyboard, your brain is rapidly sending electrical impulses
along your spinal column, and this information goes to your
hands so that you may execute voluntary typing movements. As
your fingers touch the keys, the information travels in the
reverse fashion to your brain so that you are aware of your
sensations.Additional Materials

The Brain
If you study the outer surface, you will see numerous
indentations, sulci, and bumps that are
called gyri. The sulci and gyri result from the brain folding as it
develops. It is similar to what
would happen if you take a scarf and stuff it into a small glass
container. If you do that, you
will see some of the scarf and see indentations where part of the
scarf is folded and sits on
the inside.
The part that you readily see and the part that is in the folds
comprise the neocortex of the
brain. The neocortex is often referred to as gray matter because
it is made up of neuronal cell
bodies. These cell bodies give that part of the brain a darker
appearance than what you would
see if you look at the areas that contain myelinated axonal
fibers that course through the
inside of the brain. These fibers are called white matter, and
they connect various structures
and clusters of cell bodies throughout the brain.
This white matter forms a major bridge between the two
hemispheres (halves) of the brain,
connecting the corresponding areas within the frontal, parietal,
occipital, and temporal lobes
of either side of the brain.
The table shows the various functions of the lobes of the brain.
Brain Lobe General Functions
Frontal Executive functions: Reasoning, prioritizing, and
planning;
this is the part of the brain that makes humans most
different from other animals.
Parietal Spatial orientation: It contains the sensory strip, which
helps with our spatial awareness of sensory information
(e.g., knowing which part of our body was pricked).
Temporal It contains structures that mediate learning new
information
and emotional reactions. It also contains the auditory-
processing areas.
Occipital This part of the brain is important for processing
visual
information.
Look at the image of the whole brain; you will see the
cerebellum, which sits below the rear of
the brain, below the occipital lobes.

The cerebellum, which means “little brain” in Latin, is a highly
complex structure that plays a
role in motor control and in cognitive functions.
It is a structure that is thought to exist only in jawed vertebrates
and makes up a smaller
percentage of brain matter in humans compared to some other
creatures such as birds, rats,
and elephants.

Neurodevelopment.html
Neurodevelopment
The nervous system of an embryo begins to form within weeks
of fertilization. At about two weeks, the neural tube develops. It
fills with cerebrospinal fluid (CSF) and starts to expand. The
anterior part of the tube develops into the brain as neurons and
supporting cells are produced.
As you know, neurons are cells that convey electrical and
chemical messages throughout the brain. Neuronal cells must be
created by cell division, and they must mature in a prescribed
way during specific time periods. The creation and maturation
of cells can be divided into four stages of early development:
proliferation, differentiation, myelination, and synaptogenesis.
Proliferation is a time when billions of new cells are created by
cell division. Some cells stay in an early, unspecified stage, and
we refer to them as stem cells. Others begin to transform and
take on different shapes and functions. They become various
types of neurons or glia cells and start their migration to their
predestined locations. Migration occurs when the cells follow
chemical paths that lead them to their destinations.
When it is time to migrate, the cells start to differentiate (to
become different). Differentiation is the second stage; it is
when axons and dendrites form. Axons grow first, and later,
dendrites begin to emerge. Depending on their preprogrammed
locations and functions, neurons differ in their shapes and
stored chemical components.
Myelination is the third stage of neuronal growth and
development. In this stage, axons that are predetermined to
become myelinated become coated with sections of lipids. The
lipid sections are covered by glia cells called oligodendrocytes.
The spinal cord is myelinated first, and then, the brain becomes
myelinated in a hierarchical order, with the forebrain area,
which contains the frontal lobes, being myelinated last. The
myelination process occurs gradually for
decades.Additional Materials

· How does PET scan work? State how they differ from MRI
and functional magnetic resonance imaging (fMRI). Why is
radioactively labeled glucose often used as a metabolic tracer?
What does it mean if glucose is being absorbed or used in one
area more than another?
A PET scan is called a positron emission tomography scan.
{MayoClinic, 2019)} This scan helps with taking images of the
body's tissues and organs to see how they function and their
condition. Using radioactive chemicals or a tracer that is placed
in your arm or in your veins they see how normal and abnormal
the organs are. A PET scan can help detect diseases, and the
tracer will be absorbed or go into places it detects these
diseases. So when the tracer goes into different places it means
there might be one or more places to look into for any diseases
or issues. The difference between a PET scan and MRI is that a
PET scan uses radiation and takes a long time, also more
expensive. The MRI doesn't use radiation and shorter time to
do. MRI usually works with the spinal area of the body.
· What are neural networks, and how do neural networks relate
to localized and global brain functioning? What does our
knowledge of neural networks tell us about how the brain
processes information? How do PET scans and fMRI allow us to
see the flow of information throughout networks?
A neural network is a connection of neurons. Neural networks
are made up of billion of tiny neurons which connect to each
other and they process information. They also detect brain
patterns by connections. They are also called the problem
solvers of the human brain. Simple words they are many tiny
neurons that take data and show us how the brain works. MRI
and PET while both take images differ in ways. They both
measure how much activity and blood flow in it. They both
show the waves and activity the brain is having while you think,
sleep, and even doing stuff. They use radiation and chemicals to
do these test.
· Do people only use a small percentage of their brain? Use
what you know about neural networks and functional imaging
scans to address this belief. Do you believe that we only use 10
percent of our brain capacity? Would someone be able to
demonstrate via various cognitive tasks that no part of the brain
sits in the cranium unused?
No, we don't use 10%, I feel we use a lot more than that. Do I
feel we use the whole brain, no but more 10%. PET scan and
MRI has shown us how the brain works, and the activity it has
when we are up and sleep. They show that blood flow moving
around the brain while doing test such as eating, sleeping,
reading, and evening thinking. {Cherry, 2022} The test has
shown that we actually use a huge portion of our brain. I feel
there are parts of the brain that might not be used as much as
others, but I feel the whole brain functions as a whole. I feel
that there's many test done in past and present that shown us
that parts not as active as other, but not unused.

Brain Changes.htmlBrain ChangesPonder what would happen to

  • 1. Brain Changes.html Brain Changes Ponder what would happen to the neural network if there were disruptions at different times during development. Depending on what is happening at a specific time, progress might be significantly slowed. In addition, if brain development is disrupted at certain times, progress might also end and everything that depends on the formation of that area or structure will be altered. The crucial developmental times are called critical periods of brain development. Let's look at the importance of these developmental periods. There are periods during brain development when neurons are more vulnerable to being directly harmed by introduced chemicals or stressors. During these times, development might be significantly and irrevocably harmed. One well-known example of an environmental stressor is alcohol. Heavy alcohol consumption during pregnancy might result in the child being born with fetal alcohol syndrome (FAS). Due to cell alterations, children with FAS have distinctive facial abnormalities, heart defects, motor problems, and cognitive deficits. How can the environment alter brain development? This is possible because of the neuron's ability to adjust its morphology and neurochemistry. The neuron's capacity for adaptation is called neuroplasticity. Environmentally induced neuroplasticity takes place early in the life of the fetus as the fetus is affected not only by what the mother does and eats but also the environment in which the mother lives. When the brain has been injured due to an ischemic stroke, for example, some of the brain tissue is lost and there is a corresponding change in behavior. Note that ischemia occurs when the blood flow to an area of the brain is interrupted, and during that time, the tissue beyond the blocked arterial branch

Neuroplasticity will enable this person’s brain to reorganize to compensate for damage. He may regain most of his preinjury functions as other neurons change their morphology and functional ability. Myers-Briggs type inventory type ESTJ PERSONALITY (“THE EXECUTIVE”) Summary ESTJs are representatives of tradition and order, utilizing their understanding of what is right, wrong and socially acceptable to bring families and communities together. Embracing the values of honesty, dedication and dignity, people with the ESTJ personality type are valued for their clear advice and guidance, and they happily lead the way on difficult paths. Taking pride in bringing people together, ESTJs often take on roles as community organizers, working hard to bring everyone together in celebration of cherished local events, or in defense of the traditional values that hold families and communities together. ESTJs are aware of their surroundings and live in a world of
  • 4. clear, verifiable facts – the surety of their knowledge means that even against heavy resistance, they stick to their principles and push an unclouded vision of what is and is not acceptable. Their opinions aren't just empty talk either, as ESTJs are more than willing to dive into the most challenging projects, improving action plans and sorting details along the way, making even the most complicated tasks seem easy and approachable. However, ESTJs don't work alone, and they expect their reliability and work ethic to be reciprocated – people with this personality type meet their promises, and if partners or subordinates jeopardize them through incompetence or laziness, or worse still, dishonesty, they do not hesitate to show their wrath. This can earn them a reputation for inflexibility, a trait shared by all Sentinels (SJ), but it's not because ESTJs are arbitrarily stubborn, but because they truly believe that these values are what make society work.Strengths · Dedicated – Seeing things to completion borders on an ethical obligation for ESTJs. Tasks aren't simply abandoned because they've become difficult or boring – people with the ESTJ personality type take them up when they are the right thing to do, and they will be finished so long as they remain the right thing to do. · Strong-willed – A strong will makes this dedication possible, and ESTJs don't give up their beliefs because of simple opposition. ESTJs defend their ideas and principles relentlessly, and must be proven clearly and conclusively wrong for their stance to budge. · Direct and Honest – ESTJs trust facts far more than abstract ideas or opinions. Straightforward statements and information are king, and ESTJ personalities return the honesty (whether it's wanted or not). · Loyal, Patient and Reliable – ESTJs work to exemplify truthfulness and reliability, considering stability and security very important. When ESTJs say they'll do something, they keep their word, making them very responsible members of their families, companies and communities.
  • 5. · Enjoy Creating Order – Chaos makes things unpredictable, and unpredictable things can't be trusted when they are needed most – with this in mind, ESTJs strive to create order and security in their environments by establishing rules, structures and clear roles. · Excellent Organizers – This commitment to truth and clear standards makes ESTJs capable and confident leaders. People with this personality type have no problem distributing tasks and responsibilities to others fairly and objectively, making them excellent administrators.Weaknesses · Inflexible and Stubborn – The problem with being so fixated on what works is that ESTJs too often dismiss what might work better. Everything is opinion until proven, and ESTJ personalities are reluctant to trust an opinion long enough for it to have that chance. · Uncomfortable with Unconventional Situations – ESTJs are strong adherents to tradition and when suddenly forced to try un-vetted solutions, they become uncomfortable and stressed. New ideas suggest that their methods weren't good enough, and abandoning what has always worked before in favor of something that may yet fail risks their image of reliability. · Judgmental – ESTJs have strong convictions about what is right, wrong, and socially acceptable. ESTJs' compulsion to create order often extends to all things and everyone, ignoring the possibility that there are two right ways to get things done. ESTJs do not hesitate to let these "deviants" know what they think, considering it their duty to set things right. · Too Focused on Social Status – ESTJs take pride in the respect of their friends, colleagues and community and while difficult to admit, are very concerned with public opinion. ESTJs (especially Turbulent ones) can get so caught up in meeting others' expectations that they fail to address their own needs. · Difficult to Relax – This need for respect fosters a need to maintain their dignity, which can make it difficult to cut loose and relax for risk of looking the fool, even in good fun.
  • 6. · Difficulty Expressing Emotion – This is all evidence of ESTJs' greatest weakness: expressing emotions and feeling empathy. People with the ESTJ personality type get so caught up in the facts and most effective methods that they forget to think of what makes others happy, or of their sensitivity. A detour can be breathtakingly beautiful, a joy for the family, but ESTJs may only see the consequence of arriving at their destination an hour late, hurting their loved ones by rejecting the notion too harshly. CAREERS ESTJs' career paths are often as clear and straightforward as they are themselves. Though there are many directions they can choose to go, people with the ESTJ personality type almost always end up in situations where they have the opportunity to exercise their affinity for organization, structure, and follow - through. Providing further focus, ESTJs share a profound respect for tradition, stability and security, qualities which lend themselves well to progressing along clear paths to increased responsibility and dependability. ESTJs' sense of loyalty results in them staying with a single employer as long as possible, and their reverence for established institutions often leads to work with well-respected organizations. Law enforcement, military service, hospitals and prominent legal firms are all able to recognize ESTJs' long years of service. ESTJs are the image of the model citizen, and they strive to maintain this ideal throughout their careers. This helps them move forward into management as well – people with this personality type have many traits inherent to leadership, something that is often recognized regardless of their chosen industry. From the genuine enjoyment ESTJs feel in organizing other people to their knack for clearly expressing their principles, values and expectations, ESTJs are extremely effective managers. Also fearsome leaders, ESTJs loathe disorganization, ineptitude,
  • 7. laziness and especially dishonesty, and when these values are crossed, ESTJ personalities do not hesitate to let their disapproval show. So long as everyone plays by the rules, ESTJs are incredibly efficient, their love of structure and thoroughness leaving a record of accurate, complete work that is on time and on budget. ESTJs are natural auditors, financial officers and business administrators, and any such and similar roles are excellent choices for them. Hard work and self-motivation are also strong ESTJ principles, which makes them excellent sales representatives, whether in basic retail positions, part of office teams, or as independent agents. People with the ESTJ personality type stick to projects until they're finished, big or small, and are organized enough to make any necessary paperwork a mere minor inconvenience to their clients, rather than some baffling ordeal. These qualities combine to make the clear steps in advancement that ESTJs require in order to maintain a sense of accomplishment not just viable, but almost inevitable. WORKPLACE Habits ESTJs show clear and consistent tendencies, and these are especially visible in the workplace. Whether subordinates, among colleagues or as managers, people with the ESTJ personality type create order, follow the rules, and work to ensure that their work and the work of those around them is completed to the highest standards. Cutting corners and shirking responsibility are the quickest ways to lose ESTJs' respect. ESTJ Subordinates ESTJs are hard-working and do things by the book. Though sometimes stubborn and inflexible, especially when presented with ideas that haven't been fully developed, ESTJ personalities are open to new methods that can be demonstrated to be better. However ESTJs are unlikely to do much experimenting on their own – adhering to stated responsibilities and fulfilling their duties is their primary concern. ESTJs are also well-known for their loyalty and dedication, but in some ways this is contingent on their respect. People with
  • 8. this personality type are willing to voice their opinions, especially in deciding what is and is not acceptable – if provided with sensible responses that address their concerns, they are often satisfied with that. If ESTJs view their managers as illogical, dishonest or cowardly in their methods, they can be uncomfortably honest, if still calm and level, in voicing their opinions on that as well. ESTJ Colleagues ESTJs enjoy the hustle and bustle of well-organized workplaces. Honest, friendly and down-to-earth, ESTJ personalities are great networkers who enjoy connecting with others to get things done. Abusing this for advancement is unlikely, and is in fact something ESTJs frown upon. Shortcuts are irresponsible, and people with the ESTJ personality type lose respect quickly for those who try to push forward by showing off or promoting bold but risky ideas, making relationships with more inspiration- oriented colleagues a challenge. ESTJs like to feel like they are a part of the team, and a part of the greater organization that they work for. To make sure this happens, ESTJs are nearly always willing to accept criticism that can help to improve their effectiveness, and always keep an eye on their surroundings to make sure they and their team deliver the results that are expected of them. ESTJ Managers ESTJs take genuine pleasure in organizing others into effective teams, and as managers they have no better opportunity to do so. While sometimes overbearing, even micromanaging, ESTJs' strong wills also serve to defend their teams and principles against diversions and cutbacks, regardless of who brings them. Laziness and bad work ethic are not tolerated by ESTJs under any circumstances. ESTJs project natural authority, but they sometimes expect this authority to be abided unconditionally, resisting change and demanding that things be done by the book. Whether ESTJs' own book or the existing rules and traditions are used is subject to circumstances, but they do tend to rest on the security of
  • 9. tradition and precedent. Regardless, ESTJs' expectations are clearly expressed, leaving little room or tolerance for deviation from the agenda. CONCLUSION Few personality types are as practical and strong-willed as ESTJs. Known for their reliability and administrative skills, ESTJs are good at creating and maintaining a secure and stable environment for themselves and their loved ones. ESTJs' dedication is invaluable in many areas, including their own personal growth. Yet ESTJs can be easily tripped up in areas where their rational and practical approach is more of a liability than an asset. Whether it is finding (or keeping) a partner, learning to relax or improvise, reaching dazzling heights on the career ladder, or managing their workload, ESTJs need to put in a conscious effort to develop their weaker traits and additional skills. What you have read so far is just an introduction into the complex concept that is the ESTJ personality type. You may have muttered to yourself, "wow, this is so accurate it's a little creepy" or "finally, someone understands me!" You may have even asked "how do they know more about me than the people I'm closest to?" This is not a trick. You felt understood because you were. We've studied how ESTJs think and what they need to reach their full potential. And no, we did not spy on you – many of the challenges you've faced and will face in the future have been overcome by other ESTJs. You simply need to learn how they succeeded. But in order to do that, you need to have a plan, a personal roadmap. The best car in the world will not take you to the right place if you do not know where you want to go. We have told you how ESTJs tend to behave in certain circumstances and what their key strengths and weaknesses are. Now we need to go much deeper into your personality type and answer "why?", "how?" and "what if?" This knowledge is only the beginning of a lifelong journey. Are

Neuroanatomy.html Neuroanatomy The human brain is a complex structure responsible for expressing innate abilities and retaining learned information. Our brain holds the memories and expressions that make up our personality; it is the physical configuration of who we are. The cerebellum is part of the hindbrain—one of the major divisions of the brain. Along with the cerebellum, the hindbrain contains the medulla and pons; both structures can be found in the brain stem—a complex projection that mediates many basic and life-sustaining bodily processes. The thalamus is much like a relay station for signals in the brain; the hypothalamus is associated with regulation of hormones and the drive system. The hippocampus is related to memory and the basal ganglia are related to expression and movement. The four ventricles—cavities in the brain that contain the cerebral spinal fluid—sit in the middle of the brain. This fluid serves at least two purposes—it helps remove waste from the brain and provides some cushioning during sudden movements and impacts. The CNS is one of the two major divisions of the body; the other division is called the peripheral nervous system (PNS).
  • 11. The long axonal projections of the spinal cord link the brain and the PNS. The PNS has two divisions—somatic and autonomic. The somatic system conveys incoming sensory information to the CNS and is responsible for motor messages that are sent from the CNS to the PNS. When you reach out to touch a key on your keyboard, your brain is rapidly sending electrical impulses along your spinal column, and this information goes to your hands so that you may execute voluntary typing movements. As your fingers touch the keys, the information travels in the reverse fashion to your brain so that you are aware of your sensations.Additional Materials View a Pdf Transcript of The Brain View a Pdf Transcript of The Hindbrain View a Pdf Transcript of Four Ventricles of the Brain View a Pdf Transcript of Midsagittal View of the Brain media/week2/SU_PSY4490_W2_L2_S1_G1.pdf Page 1 of 2 PSY4490_Biological Psychology © 2012 South University The Brain If you study the outer surface, you will see numerous indentations, sulci, and bumps that are called gyri. The sulci and gyri result from the brain folding as it develops. It is similar to what would happen if you take a scarf and stuff it into a small glass container. If you do that, you
  • 12. will see some of the scarf and see indentations where part of the scarf is folded and sits on the inside. The part that you readily see and the part that is in the folds comprise the neocortex of the brain. The neocortex is often referred to as gray matter because it is made up of neuronal cell bodies. These cell bodies give that part of the brain a darker appearance than what you would see if you look at the areas that contain myelinated axonal fibers that course through the inside of the brain. These fibers are called white matter, and they connect various structures and clusters of cell bodies throughout the brain. This white matter forms a major bridge between the two hemispheres (halves) of the brain, connecting the corresponding areas within the frontal, parietal, occipital, and temporal lobes of either side of the brain. The table shows the various functions of the lobes of the brain.
  • 13. Brain Lobe General Functions Frontal Executive functions: Reasoning, prioritizing, and planning; this is the part of the brain that makes humans most different from other animals. Parietal Spatial orientation: It contains the sensory strip, which helps with our spatial awareness of sensory information (e.g., knowing which part of our body was pricked). Temporal It contains structures that mediate learning new information and emotional reactions. It also contains the auditory- processing areas. Occipital This part of the brain is important for processing visual information. Look at the image of the whole brain; you will see the cerebellum, which sits below the rear of the brain, below the occipital lobes.

  • 16. © 2012 South University Midsagittal View of the Brain Neurodevelopment.html Neurodevelopment The nervous system of an embryo begins to form within weeks of fertilization. At about two weeks, the neural tube develops. It fills with cerebrospinal fluid (CSF) and starts to expand. The anterior part of the tube develops into the brain as neurons and supporting cells are produced. As you know, neurons are cells that convey electrical and chemical messages throughout the brain. Neuronal cells must be created by cell division, and they must mature in a prescribed way during specific time periods. The creation and maturation of cells can be divided into four stages of early development: proliferation, differentiation, myelination, and synaptogenesis. Proliferation is a time when billions of new cells are created by cell division. Some cells stay in an early, unspecified stage, and we refer to them as stem cells. Others begin to transform and take on different shapes and functions. They become various types of neurons or glia cells and start their migration to their predestined locations. Migration occurs when the cells follow chemical paths that lead them to their destinations. When it is time to migrate, the cells start to differentiate (to become different). Differentiation is the second stage; it is when axons and dendrites form. Axons grow first, and later, dendrites begin to emerge. Depending on their preprogrammed locations and functions, neurons differ in their shapes and stored chemical components. Myelination is the third stage of neuronal growth and
  • 17. development. In this stage, axons that are predetermined to become myelinated become coated with sections of lipids. The lipid sections are covered by glia cells called oligodendrocytes. The spinal cord is myelinated first, and then, the brain becomes myelinated in a hierarchical order, with the forebrain area, which contains the frontal lobes, being myelinated last. The myelination process occurs gradually for decades.Additional Materials View a Pdf Transcript of Brain Developing from the Neural Tube media/week2/SU_PSY4490_W3_S2_G2.pdf Page 1 of 1 PSY4490_Biological Psychology © 2012 South University Brain Developing from the Neural Tube Week 2 Discussion Contains unread posts Cristina MCBRIDE posted Jul 20, 2022 8:28 PM Subscribe South University Cristina McBride · How does PET scan work? State how they differ from MRI and functional magnetic resonance imaging (fMRI). Why is radioactively labeled glucose often used as a metabolic tracer? What does it mean if glucose is being absorbed or used in one area more than another?
  • 18. A PET scan is called a positron emission tomography scan. {MayoClinic, 2019)} This scan helps with taking images of the body's tissues and organs to see how they function and their condition. Using radioactive chemicals or a tracer that is placed in your arm or in your veins they see how normal and abnormal the organs are. A PET scan can help detect diseases, and the tracer will be absorbed or go into places it detects these diseases. So when the tracer goes into different places it means there might be one or more places to look into for any diseases or issues. The difference between a PET scan and MRI is that a PET scan uses radiation and takes a long time, also more expensive. The MRI doesn't use radiation and shorter time to do. MRI usually works with the spinal area of the body. · What are neural networks, and how do neural networks relate to localized and global brain functioning? What does our knowledge of neural networks tell us about how the brain processes information? How do PET scans and fMRI allow us to see the flow of information throughout networks? A neural network is a connection of neurons. Neural networks are made up of billion of tiny neurons which connect to each other and they process information. They also detect brain patterns by connections. They are also called the problem solvers of the human brain. Simple words they are many tiny neurons that take data and show us how the brain works. MRI and PET while both take images differ in ways. They both measure how much activity and blood flow in it. They both show the waves and activity the brain is having while you think, sleep, and even doing stuff. They use radiation and chemicals to do these test. · Do people only use a small percentage of their brain? Use what you know about neural networks and functional imaging scans to address this belief. Do you believe that we only use 10 percent of our brain capacity? Would someone be able to demonstrate via various cognitive tasks that no part of the brain sits in the cranium unused? No, we don't use 10%, I feel we use a lot more than that. Do I

They show that blood flow moving around the brain while doing test such as eating, sleeping, reading, and evening thinking. {Cherry, 2022} The test has shown that we actually use a huge portion of our brain. I feel there are parts of the brain that might not be used as much as others, but I feel the whole brain functions as a whole. I feel that there's many test done in past and present that shown us that parts not as active as other, but not unused. References Cherry, K. (2022, April 19).
