The Power of the Human Brain

The Power of the Human Brain Essays
Introduction
Humans have been considered the highest form of living things on earth . This is not attributed to
the fact that the human body is strong or agile , because there are multiple animals that possess
strength and agility far beyond the imagination of humans . The main characteristic that
distinguishes humans from all other organisms is the brain . The brain is the powerhouse of the body
. However this is also the site of the mind . The mind has been said to give humans superior status
over other creatures . With this one significant characteristic, humans have the ability to reason ,
feel and adapt . Man has crossed many miles stones beyond the capabilities of any other living thing
ad there are many more feats to be reached...show more content...
The Cerebellum is located at the back of the brain , under the occipital and temporal lobes of the
cereral cortex . and contains about 50% of the neurons in the brain and has been nicknamed the
motor structure of the brain, due to the fact that a damaged cerebellum affects motor control and
posture .The cerebellum performs the following functions
Maintains Balance and Posture
Coordination of voluntary movement
Motor Learning
Cognitive functions
The Cerebellum is built from four different types of neurons which include granule cells, Purkinje
cells and two types of inhibitory interneurons (Golgi cells and basket cells)
The Brain Stem is on the bottom of the brain and is between the deeply rooted structures of the
cerebral hemisphere and the cervical spinal cord. It is split into three sections or departments ,
midbrain(mesencephalon), pons(metencephalon and medulla oblongata 9myelencephalon). The
brainstem which is storage for many control houses of the body that include functions like
swallowing, breathing and vasomotor control. Cranial nerve nuclei is located in the brainstem with
the exception of the ones associated with the olfaction and vision, these provide motor and sensory
functions to the different structures in the cranium, e.g. facial muscles, tongue ,larynx and pharynx ,
it also serves the purpose of supplying the senses of taste, equilibrium and hearing . Complete loss
of brainstem has been regarded by

Canadas Brain Drain Issue Essay
Canadas Brain Drain Issue What is a brain drain? It is the emigration of highly educated and skilled
Canadians to the United States. Does Canada suffer from a Brain Drain? This is a question that
economists have been trying to answer for a decade now and have conducted different studies
resulting to different conclusions about this issue. There are some economists that believe that yes
Canada is suffering from a brain drain if not now it will be soon, amongst those economists are
Don DeVortez and Samuel Laryea who prepared a study of C.D howe Institute. They claimed that
Brain Drain is real and is costing Canada Tax Payers millions of dollars. Then on theother side of the
debate we have economists like John Helliwell, who...show more content...
"I believes in the queen bee theory, that one real talented leader, can create all kinds of enterprise
and wealth" said the CEO of a major corporation in Western Canada. " If you lose that one person
or that small group of people to places that they would rather be, they're not going to come back
and you're going to lose a tremendous amount of wealth creation" He was responding to
Helliwell's theory saying that the flow of migrants from Canada to the United States, whether
overall or only among the highly educated, are less than a quarter as large as those in the 1960's.
The CEO is trying to say that maybe the flow of migrants are less but we are losing key players and
that in the long run it will definitely hurt our nation. If the talent is moving away from Canada
because of better benefits less tax then the companies will follow the people that drive success and
hence the low number of migrants will eventually add up to millions of dollars of loss, and at this
point millions of dollars is definitely a problem that the government needs to address and fast.
Helliwell argues that over the last 30 years, there has been a steady continuation of the century–long
downward trend in the number of Canadian–born residents in the United

Essay on Brain Cancer
The brain is made up of millions upon millions of cells. These cells are formed from before birth,
up until about 7 years old. Once these brain cells stop dividing, they are never meant to divide
again. You can see that the division of brain cells is under strict regulation and control. When this
control is lost in a single cell, then it starts dividing in an uncontrolled manner. All of the data
obtained through research on cancer shows that this disease is caused by a rapidly dividing cell,
with no regulators to stop it from dividing. As the cell makes more and more copies of itself, it
grows to form a tumor. This is known as cancer.
When a tumor is developed on the brain, it is called a brain tumor or brain cancer. Brain tumors can

Heredity also plays a role in the development of cancer. If a person's relatives have a history of
cancer, then that person has a higher risk of developing cancer. Genetic variations, particularly those
influencing how the body responds to carcinogens, may create a greater vulnerability to cancer.
Brain cancer is usually accompanied at first by headaches and seizures. Later symptoms could
include nausea, vomiting, fever, change in pulse, and trouble breathing. Other mental changes may
also occur such as difficulty in communication. Symptoms greatly depend on the location of the
tumor. For example, if the tumor were located on the part of the brain controlling vision, then vision
would be affected.
Once a person has been diagnosed with brain cancer, treatment should begin immediately. Treatment
for brain tumors involves any combination of surgery, radiation, and chemotherapy. Some tumors
require several different surgical procedures; some can be treated with radiation alone. Surgery is
the best process to remove a brain tumor. Surgery attempts to remove most, if not all of the tumor.
Once most of the tumor is removed, the rest of the tumor can be removed through a process called
radiotherapy.
Radiotherapy, also called radiation therapy, is the treatment of cancer and other diseases with
radiation. Radiotherapy is used when the entire primary tumor cannot be surgically removed.
Radiotherapy deposits energy

Brain Disease Essay
What would you do if you had brain disease? The brain is the most important part of the human
body. Without it, you would not be able to think, and more importantly, you would be dead. Two
serious brain diseases are brain tumors and Alzheimer's disease. A brain tumor is a massive growth
of abnormal cells in the brain. There are many types of brain tumors. Some may be benign, which is
noncancerous, or they may be malignant, which is cancerous (Brain Tumor). Alzheimer's disease is
an unstoppable brain disease that gradually damages one's memory and thinking. Eventually, the
ability to do simple tasks everyday even becomes destroyed. For most people, Alzheimer's disease
show after the age of 60. This is known as late onset AD. Early onset is...show more content...
The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning,
planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with
balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal
lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain
more convenient, as this increases the brain's surface area, giving it more room for neurons. The
cerebrum is divided into two hemispheres– the left hemisphere, and the right hemisphere. The right
hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve
fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their
Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum,
since it also has two hemispheres and a highly folded surface. This part of the brain is linked with
movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily"
(Brain Structures and Their Functions). The brain stem controls basic life functions such as blood
pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain
(Brain Structures and Their Functions).
Dementia is the loss of intellectual processing such as thinking, reasoning,

Essay about AlcoholвЂ™s Effects on the Brain
Alcohol seems to be a common topic for teenagers in today's society. Mainly alcohol is consumed
by adolescents that are bored or trying to fit into a crowd by attempting to look 'cool'. Students are
aware of the effects but why is nothing being done? There are many consequences that come along
with drinking; alcohol negatively affects not only the body, but thebrain.
Alcohol is officially defined as 'a colorless volatile flammable liquid, C2H5OH, synthesizes or
obtained by fermentation of sugars and starches and widely used as a solvent and in drugs' according
to thefreedictionary.com, but it is much more than that. The human brain does not stop growing until
the person is in their late 20's. Because the brain is still developing rapidly...show more content...
Now, obviously these two groups have a big gap in between them, but both types of drinkers are
still affected by alcohol consumption. Neuroimaging has helped scientists study the structure and
functions of the brain (Squeglia 1). Blobs of gray matter in the brain and connections for
communication between the lobes, and white matter connect the gray matter. Sometimes, when
alcohol is in the brain, white matter quality cannot reach the full density resulting in an
abnormality. Reduction of gray matter also occurs and the unwanted connections are demolished
between the prefrontal and temporal lobes because of alcohol usage (Paturel 1). The blood flow
of the brain is below average and can cause significant damage to tissues in the brain. The flow of
the blood cannot efficiently reach the brain and brain functions are altered. Light and heavy
drinkers suffer from poor spatial working memory. Alcohol can also affect the verbal part of the
brain and there can be poor verbal learning and processing (Mattson 2). A study compared
adolescents that drink with adolescents that do not drink and found that the adolescents that drank
remembered 10% less information than the kids that did not drink. These findings have been
consistent over the years (Squeglia 3). Over a time span of drinking, significant changes are
happening in the brain but cannot be seen. The hippocampus is one of the most vulnerable parts of
the

Essay The Aging Brain
The Aging Brain Why does the human brain age? Brain aging is a part of human life and a big
part of society as the awareness for brain aging increases. Over time memory tends to become less
efficient as we age and the neurons in the brain decreases (Bendheim, P.E. (2009). By 2050 in the
US, 20 percent of the population will be 65 years or older. And as the elderly population increases,
so will the incidence of age–related neurological disorders (Perlmutter, David. (2004). Therefor it is
important to understand the aging brain, and how to keep the brain functioning as one ages. As age
increases, we can expect some loss of heart, lung, joint, and sexual functioning. Some loss of brain
cells and mental efficiency is a normal part of...show more content...
In many cases mild age–related memory loss is considered normal, but more severe memory
impairments are not. What is a stroke and how is it related to the aging brain? A stroke happens
when the blood supply to your brain is interrupted or it is reduced, depriving the brain tissues of
oxygen and food (Bendheim, P.E. (2009). Within minutes of a stroke brain cells begin to die.
Early action can minimize brain damage and potential complications. A stroke can cause
temporary or permanent disabilities, depending on how long the brain suffers the lack of blood
flow (Perlmutter, David. (2004). Some complications after a stroke are; paralyzation (loss of
muscle movement), memory loss, and trouble talking. Paralyzation is due to the lack of blood
flow to the brain, a patient can lose movement in one side of the body. Stroke can damage too
many parts of the brain, and it can start an early brain aging. A stroke can cause a patient to loss
control over the way muscles in the mouth move, have difficult talking and eating (Bendheim, P.E.
(2009). But one can try to prevent a stroke by taking care of their high blood pressure, high
cholesterol, and smoking. Dementia is also part of the aging brain. One in seven people ages 71 and
older has dementia, but that figure rises to

The Brain and Cranial Nerves Essay examples
The Brain and Cranial Nerves
One of the most complex and fascinating things in the human body is the brain. The body is
"capable of almost everything, but it would not be possible, without the brain receiving information,
and analyzing the information."
The brain is aware of its surroundings, via input from the spinal cord and cranial nerves. Cranial
nerves with sensory functions allow us to smell and see. Nerves with both motor and sensory
functions are responsible for everything from tasting and chewing, to breathing and the heating of
your heart. Many of the little things we take for granted are also made possible by cranial nerves.

Because virtually no glucose is stored in the brain, the supply of glucose also must be continuous. If
the blood entering the brain has a low level of glucose, mental confusion, dizziness, convulsions, and
loss of consciousness may occur.
The blood brain barrier protects brain cells from harmful substances, as well as, pathogens, by
preventing passage of many substances from blood into brain tissue.
Tight junctions seal together the enclothelial cells of brain capillaries, which also are surrounded by
a thick basement membrain. The process of many astrocyties pressing up against the capillaries is
known as the Astrocyties Process. This process selectively passes some substances from the blood to
the neurons, at the same time, inhibiting the passage of others.
A few water soluble substances, like glucose, cross the brain blood barrier by active transport. Other
substances like creatinine, vrea, and most ions, cross very slowly. Other substances and protions,
including most antibiotic drugs, do not pass at all from the blood into brain tissue. Trauma, certain
toxins, and inflammation, can all cause a breakdown of the Brain blood barrier.
The cranium and the Cranial Meniges surround and protect the brain. The Cranial meninges are
continuous with the Spical meninges. Both have the same basic

Most of migrations from developing countries are those wealthy or skilled people, whose leaving
results in brain drain and slow development of home countries. This contributes to a vicious circle
for developing countries (low–income countries). On the other side, the advantaged social
environment (rich opportunities, comparatively good political system, developed economy, better
living conditions, etc) in developed countries attract talents from other areas, which contribute to
brain grain, and finally forms a virtuous circle. * Concept and Magnitude of Brain Drain Migration
of people as a phenomenon differs from country to country and from time to time. It is misleading to
generalise about the possible effects of migration from LDCs. But even more fundamentally, one can
argue that different studies are measuring differing things. All migrations cannot be justifiably
brought within a single analytic umbrella, though it has been so done in the contemporary literature
on the subject. Migration of HQM from LDCs may be due to several different sets of underlying
social, political and economic forces. The phenomenon of migration of high quality manpower can
justify the use of the expression on the term "brain drain", but one has to be cautious in using the
expression drain indiscriminately. To replace "drain" by a

Essay about the human brain
In this paper one will learn the different parts of the brain and their functions. Although the brain isn't
the largest organ of the human body it is the most complex and controlling organ. It is amazing how
complicated the brain is. The brain controls every action within and out of your body. The brain has
main areas that contain different areas that have specific functions. For instance the basal ganglia
holds the lentiform and the caudate.
The brain isn't just "THE BRAIN" it is actually a group of many parts. They help to inform the brain
on the things going on with the human body. The brain is split in to two main parts, the left and the
right hemisphere. The left hemisphere has about the same areas as the right hemisphere. The only

The corpus callosum is a bundle of nerves that connects the two hemispheres. The area that passes
and processes information concerning touch, pain, temperature, and pressure on skin is the
thalamus. The limbic system controls your behavior and emotions. It is involved in emotions such
as fear, rage, pleasure, and sorrow. In the prefrontal area of the frontal lobe emotional traits are
controlled. In the temporal lobe expressed behavior is controlled. The parietal lobe discriminates
sensory. The occipital lobe is where visual interpretation takes place. Pons is a crossroad for nerves
going up to the cortex, to the cerebellum and then down the spinal cord. The cortex is the outer gray
area where thinking takes place. The olfactory cortex receives senses from the nose that it then sorts
out. The area that identifies what we see by working out movements, colors, and shapes is the visual
cortex. The area that receives taste senses is called gustatory cortex. The area responsible for
analyzing data, performing memory functions, learning new information, forming thoughts, and
making decisions is the cerebral cortex. The motor cortex is involved in muscle movement. The
cerebellum is vital when carrying out complicated, skilled movements. It is much like a mini brain.
If before you read this paper you thought the brain was a "one man machine" I'm sure your opinion
has changed after reading his paper. It is amazing how god has created the brain to have so many

Essay On Brain Trauma
It was my first day of college, I'm sitting in my desk getting a notebook out and making sure I
didn't forget my planner at the dorm, when someone asks me, "what did you do to your arm?", I
mumbled "I had a plate removed", and left it at that. Consequently, I began the think about what I
did on July 26th, 2016. Eventually I will go into greater detail, but to quickly sum it up, I crashed
my car that night. I was in the hospital for about ten days, I was treated for severe brain trauma, a
broken elbow, and a fracture in my skull, ribs, and shoulder. I'm not glad I received some nasty
injuries, but it caused me to realize a lot that I needed to do for myself in order to be organized
and prepared to continue my education and my life. Summer was coming to an end, I was about
to be on my way to California to attend college in Santa Barbara, I was trying to enjoy myself in
my final days at home. I was booking tickets to go to Santa Barbara to check out a place to stay,
when I asked a girl to hang out that evening, and to my surprise she said yes! I dated her freshman
year of high school, dumped her and she started dating my best friend, well old best friend but that's

It is absolutely horrible, yet it was the most interesting experience of my life. It helped me
understand how my mind actually works, in depth understanding of why I am the way I am. Sure, I
sound pretty crazy right now, but you will never be able to fully understand it unless you experience
it. Life will now always be how I was before the crash and how I am now, its kinda like I lived one
life and obviously I didn't die, but it feels like life is absolutely different post crash, not in a bad
way. My battle is still not over, at about the two year mark I will be as healed as I can be, from
everything I've read, I'll never be back to 100%. All that does for me is give me a challenge, a big
