This document provides an overview of left-brain and right-brain functions based on split-brain research. It discusses:
- The brain is divided into left and right hemispheres connected by the corpus callosum.
- Research found the hemispheres have specialized but complementary functions - the left hemisphere is dominant for language and logical/sequential thinking while the right hemisphere is dominant for spatial skills, creativity, and holistic thinking.
- Brain scanning technology has furthered understanding of how the brain specializes in tasks but also coordinates between hemispheres through bi-lateral transfer of information.

According to Wikipedia.org fake news is a type of yellow journalism or propaganda that consists of deliberate misinformation or hoaxes spread via traditional print and broadcast media or online social media. Fake news is written to mislead in order to damage an agency or person and most of the time we can see this fake news on Facebook and twitter. Fake news confuse us to what is real and what is not sometimes because of this we are lead to wrong information that sometimes can cause panic and social media war. Now that that our society is in lowest form we are more oblige to scan all of the information we receive, filter it and distinguish fact from fake news.
In distinguishing fake news from fact we should remember this 7 reminders : (1) consider the source (2 )check the author (3) check the date (4) check your biases (5) read beyond (6) site supporting sources (7) Analyze.
As a millennial we should be more sensitive and smart in everything we see and post because a single post can build relationship but it can also destroy.
Human brain understanding the complex structureAnupama Saha
The human brain is the central organ of the human nervous system, along with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem as well as the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and guarded by, the skull bones of the head.
The cerebrum is the largest of the human brain. It is divided into two cerebral hemispheres. The cerebral cortex is an outer layer of grey matter, covering the core of the white matter. Each hemisphere is conventionally divided into four lobes – the frontal, temporal, parietal, and occipital lobes. Within each lobe, cortical areas are associated with specific functions, such as the sensory, motor and association regions. Although the left and right hemispheres are broadly similar in shape and performance, some functions are related to one side, like language within the left and visual-spatial ability on the right. The hemispheres are connected by the corpus callosum.
The brainstem consists of the midbrain, the pons, and the medulla oblongata. The cerebellum is connected to the brainstem by pairs of tracts. Underneath the cerebral cortex are several important structures, including the thalamus, the epithalamus, the pineal gland, the hypothalamus, the pituitary gland, and the subthalamus; the limbic structures, including the amygdala as well as the hippocampus; the claustrum, various nuclei of the basal ganglia; the basal forebrain structures, and the three circumventricular organs. The cells of the brain include neurons and supportive glial cells. There are more than 86 billion neurons within the brain. Brain activity is possible by the interconnections of neurons and their release of neurotransmitters in response to nerve impulses. Neurons connect to form neural pathways, neural circuits, and elaborate network systems. The whole circuitry is driven by the method of neurotransmission.
The study of the anatomy of the brain is neuroanatomy, while the study of its function is neuroscience. Numerous techniques are used to study the brain. Medical imaging technologies like functional neuroimaging, and electroencephalography (EEG) recordings are important in studying the brain. The medical history of people with a brain injury has provided insight into the function of each part of the brain.
Hemispheric specialization also known as cerebral lateralization refers to the functional asymmetry between the left and teh right hemispheres of the brain. This phenomenon allows each hemisphere to process certain cognitive functions differently.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

LESSON 5: LEFT-BRAIN/RIGHT-
BRAIN
INTRODUCTION
Can you imagine what your brain
looks like? Close your eyes for a few seconds
and visualize it positioned in the space inside
your head; then, open your eyes again.
What did you see? Actually, your
brain looks like an English walnut with the
shell removed. It has a deeply wrinkled
surface with a clearly marked fold that divides
it into a left and a right half.
Another way to visualize what your
brain looks like is by doing the following
demonstration. Make a fist with both hands
and put them together in front of you, about
chest high and knuckles up. Look down at
your fists. This will give you an idea of the
physical appearance of your brain. From this
view, you can clearly see the separation
between the left and right halves. The
following four illustrations show you other
views of your brain.

Why is the brain divided into a left
and right side? For hundreds of years, scien-
tists believed that the two sides were mirror
images of each other. Since nature equips us
with two eyes, ears, legs, and kidneys that
perform the same function, why not both
sides of the brain?
Only within the last forty years has
science shown that the left and right-brain
hemispheres have unique and specific func-
tions. Before this breakthrough, brain function
was a mystery. More than ninety percent of
all science known about the brain is directly
or indirectly related to left-brain/right-brain
research, which scientists also refer to as split
brain or hemisphere specialization research.
SPLIT BRAIN RESEARCH
In the 1950s and early 1960s, neuro-
surgeons who were treating patients with
uncontrollable epileptic seizures decided to
perform a radical type of brain surgery. They
completely separated the two halves of the
brain, creating a split brain, by cutting
through the corpus callosum, the bundle of
fibers that connects these halves. To the doc-
tors’ surprise and pleasure, these patients
suffered no change in intelligence, personal-
ity, or daily function, and their seizures
stopped.
However, split-brain patients did
report oddities and curiosities (such as, one
patient had difficulty learning to associate
names with faces, many patients had subtle
memory difficulties, and most patients com-
plained that they no longer dreamed). These
reports initiated a tremendous interest in
research, thus creating a rapid buildup of
knowledge about the brain.
Research in sleep labs proved that
split-brain patients do indeed dream, indicated
by a special brain wave pattern and rapid eye
movement below the closed eyelid. These
patients could not remember their dreams
because one side of the brain is responsible
for dream activity and the other side records
the dream into words. Because the doctors
had disconnected the two sides, the brain
could not share this information between the
two hemispheres.
Other research suggested that the two
sides of the brain have a specific set of
functions. Victims of automobile accidents
3. Chapter 1: Know Yourself — Socrates Lesson 5: Left-Brain/Right-Brain
Unit 3: Foundations for Success 25
with injuries to the left side of the head lost
the ability to speak, but they could still sing.
Persons with right-brain damage lost memory
of faces and an orientation to their sur-
roundings, even their home (referred to as
spatial orientation). These early findings
illustrated that speech and language functions
are on the left side of the brain and facial
recognition, spatial orientation, and music
functions are on the right side. Both hemi-
spheres of the brain are involved in higher
cognitive functioning; with each half of the
brain specialized in complimentary fashion.
HEMISPHERIC SPECIALIZATION
The expression — left-brain/right-
brain — refers to specialized functions of the
two hemispheres. Scientific research with
healthy human subjects used a new brain scan
technique called Positron Emission Tomog-
raphy (PET) scan to confirm these findings.
Individuals were connected to a
machine that mapped brain activity by
lighting up to show which part of the brain
was active. In a typical experiment, the
researcher gave each subject a series of tasks
to perform, and then recorded which side of
the brain was most active. Results indicated
that activities involving numbers, logic, word
puzzles, sequential tasks and analysis were
more active on the left side of the brain;
whereas activities involving music, imagin-
ation, colors, or creative expression were
more active in the right hemisphere. Evidence
suggests that the right-brain has a global bias
while the left-brain has a local bias. In other
words, the right hemisphere sees the picture
and the left hemisphere sees the components
of the picture.
The distinctiveness of the left and
right-brain functions has led to the notion that
humans have two brains. Although research
shows that each hemisphere may be in charge
of a specific set of functions, neither side has
exclusive control of those functions. Both
sides can interchange roles.
The illustration on the next page
graphically displays a summary of those
functions for both sides of the brain.
BRAIN HEMISPHERE LEARNING
Research identifies the left-brain as
the Academic Brain because educators gen-
erally emphasize its processes in the tradi-
tional classroom, resulting in certain groups
using hemisphere specialization to explain
limitations of traditional learning. On the
other hand, research identifies the right-brain
as the Artistic Brain because it is in charge of
creative talents.
Although fields such as science and
medicine now pay more attention to these
brain processes, education has traditionally
neglected the right side, leaving half of a
student’s brain potential undereducated.
However, more and more school systems are
using whole-brain learning techniques.
Recently, educational researchers have
shown that a balanced involvement of both
sides of the brain in the classroom can create
surprising learning gains in many types of
students: children, adult learners, the so-called
“mentally dull,” and the genius. Thus, these
studies conclude that learning can proceed at
astounding rates when teachers have students
integrate both sides of their brain in a lesson.
For example, kindergarten teachers who use
music, dance, storytelling, drama, or numer-
ous other right-brain activities as part of their
routine teaching strategy not only aid the left-
brain learning of their students, those also
learn at incredible rates. After third grade,
when the use of these aids typically
diminishes, learning rates drop significantly
as well.

BRAIN HEMISPHERES
The brain splits up functioning and
then coordinates and synchronizes informa-
tion processing from the two hemispheres.
Split-brain research back in the 1960s resulted
in some early views of a logical-creative
functional split. This simplistic understanding
has evolved to a more complex view.
Brain scanning technology has been
instrumental in furthering our knowledge base
in the area of brain function, specialization,
and synchronization. The brain devotes areas
to specialized tasks. For example, there are
clearly areas in the cortex devoted to visual
and auditory data, as well as areas that deal
specifically with language, memory, and so on.
Different, specialized brain areas
process related information at the same time
(such as visual data, sound, and smells).
These associations enhance long-term
memory storage. These “initial,” or “level-
one” processing areas then transfer (hence the
term bi-lateral transfer) processed data onto
another area for higher level thinking skills
and further processing. Distinct data is then
integrated.
Bi-lateral transfer refers to the ability
of the brain to transmit data processed in one
hemisphere and coordinate and integrate it
with data processed in other areas. The
processing appears to take place in levels.

That is, initial processing seems to focus on
the sensory input. Integration occurs between
areas. Higher-level thinking skills get
involved to make sense of the data.
This all happens very quickly, but
there is both a sequential nature and a
spiraling nature to the increasingly complex
processing that occurs. That is, the brain has
the ability to apply increasingly sophisticated
analytical and evaluative thinking and it does
so progressively. The brain also synthesizes
new information and experiences with exist-
ing knowledge, memories, beliefs, values, and
emotions.
THE DOMINANT SIDE OF THE BRAIN
This lesson introduces you to the con-
cept of brain preference, or brain hemisphere
dominance, and explains brain preference
from a personal, cultural, and career perspec-
tive. In class, you may have the opportunity to
complete a brain preference test that will tell
you which part of your brain you prefer.
As more knowledge about the brain
became available, professionals in fields such
as science, medicine, and education asked
more questions. One interesting line of
research explored the question of whether
people rely on one side of the brain more than
the other. Is one side of the brain dominant?
Researchers believe that brain
dominance determines a person’s preferences,
problem-solving style, personality character-
istics, and even career choices. For example, a
right-brain individual will quickly get a
feeling for a situation, while a left-brain
person will usually ask a lot of questions first.
The following chart reflects additional
differences between left and right-brain
dominance.
PERSONAL PREFERENCE
LEFTDOMINANCE RIGHT DOMINANCE
Classical music Popular music
Being on time A good time
Careful planning To visualize the
outcome
To consider
alternatives
To go with the first
idea
Being thoughtful Being active
Monopoly, scrabble,
or chess
Athletics, art, or
music
There is nothing good or bad about
either preference. Both orientations can be
equally successful in accomplishing a single
task; however, one may be more appropriate
over the other depending on the situation.
HOW BRAIN PREFERENCE
DEVELOPS
Researchers have determined that
brain preference does not come from a
person’s conscious choice about which side of
the brain to use. However, what they want to
know more about is whether children inherit
their brain preference from their parents
(obtained from nature), it is socialized from
early childhood experiences (obtained from
nurture), or a combination of both. Different
studies on how brain preference develops
suggest that:
• Dominance is present at birth, but that
children may not be able to establish it
well until they are five years old — while
other studies suggest that children
continue to develop their brain preference
until they reach puberty.
6. Chapter 1: Know Yourself — Socrates Lesson 5: Left-Brain/Right-Brain
28 Unit 3: Foundations for Success
• A strong relationship exists between the
brain preference of infants and their
parents, suggesting that genetics has a
major influence on brain preference.
• Early childhood experiences, or nurturing,
can play a major part in brain preference
development.
DOMINANCE AND CAREER CHOICE
As children grow, they will continue
to prefer activity on one side of the brain,
which eventually can reflect in their choice of
a major in college or a career preference.
College students who major in literature and
the humanities show a greater degree of right-
brain activity, compared to those majoring in
science and engineering, who show high left-
brain activity.
Studies have also indicated that brain
dominance can be inferred from a person’s
occupation. Typically, lawyers, chemists,
mathematicians, and accountants are left-
brain dominant because these occupations
require logical, sequential, and analytical
skills. Characteristically, musicians, actors,
athletes, and artists are right-brain dominant
because they rely on right-brain functions
such as body sensing, rhythm, color imagery,
and spatial orientation.
Distinctions in brain preference also
exist in the same occupation. Corporate and
contract lawyers are often more left-brain
oriented than domestic and criminal lawyers.
Rock musicians and recording artists are often
more right-brain dominant than classical
musicians. Successful managers and
administrators in the same field may have a
different brain dominances. The manager who
works well with people most likely have a
right-brain tendency, while administrators
who do a lot of planning will tend have the
left-brain dominance. Careers in the military
follow this same pattern — some are more
left-brain oriented while others are more
right-brain oriented.
YOUR OWN BRAIN PREFERENCE
By now you are probably very curious
about your own brain preference, and have
definite feelings about which side you prefer.
Knowing your brain preference is important
because it determines certain likes, dislikes,
skills, and weaknesses.
These preferences may develop very
early in your life and may become more
extreme as you develop and grow older. For
instance, if you are good at basketball, but not
at reading, you would most likely spend more
time playing basketball than reading. Thus,
your abilities and personality may become
one-sided. To become a well-rounded,
actualized person, you need to consciously
develop the less preferred side of your brain.
THINKING BETTER
In today’s society, a crisis exists in
how people think — that is, oftentimes people
do not think independently or creatively. This
lesson gives you the opportunity to examine
how you think, how you can improve your
thinking process, your problem-solving style,
and how to balance brain functions to obtain
better results. Successful people know how to
use their whole-brain functions in order to
solve their problems successfully.
VERBAL AND VISUAL THINKING
Each side of the brain has its own
thought process, which appears in our
conscious mind as voices or pictures. The
left-brain produces verbal thought while the
right-brain creates pictures or visualizations
(known as visual thought). Researchers also
believe that emotional feelings, hunches, gut
reactions, etc. — which people attach to these
7. Chapter 1: Know Yourself — Socrates Lesson 5: Left-Brain/Right-Brain
Unit 3: Foundations for Success 29
voices and pictures — represent a third brain
input called kinesthetic thought. The com-
bination of these three processes is the way
people program their brains to accomplish
their life goals.
VERBAL THOUGHT
People experience verbal thought
through self-talk. Psychologists use self-talk
extensively today to help individuals with
many of their life problems by giving them
“thought-stopping” techniques to break the
habit of negative thinking. For example, star
athletes go to sport psychologists to learn how
to apply positive self-talk to improve their
game. Statements used to condition positive
self-talk are affirmations — high quality
statements that promote successful thinking
and feeling. People who make the most of
affirmations like them so much that they
adopt them as personal slogans. Additionally,
thinking about an affirmation and repeating it
over and over will make it a part of an
individual’s self-talk, programming the brain
to bring about the desired end result.
The affirmations listed below are
examples that one can use to promote success
in learning (the first group of four) or for life
in general (the second group of four).
• Learning is something I enjoy immensely.
• Learning is inside me just waiting to
happen.
• My memory is sharp; my mind is
powerful.
• I recognize the right answers at the right
time.
• I am kind, patient, and compassionate
with myself.
• I stand tall inside myself.
• I have the energy and determination to
tackle and solve my toughest problems.
• I have everything it takes to achieve my
goals, beginning now.
VISUAL THOUGHT
The visual pictures that you form in
your mind may be crystal clear and in full
color or they may be fuzzy, fragmented, and
unstable. Some people visualize only in black
and white; others do not make pictures at all.
People also experience visual thought while
they are daydreaming. As a child, visual
thinking is prevalent, but by fourth or fifth
grade, outside influences can discourage
children from daydreaming. Many adults
consider it to be a waste of time. However,
visual thought is very important and is the
beginning point of anything new in one’s life.
Everything created by humans once existed as
a picture in somebody’s mind.
The old expression — “a picture is
worth a thousand words” — means that
visual pictures impress the memory better
than verbal thoughts. For example, students
who routinely visualize what they read in
books perform better on tests and most people
remember faces longer than names. Our
society may give verbal thinking more
importance, but it appears that visual thinking
has more brainpower. The following
examples are ways you can develop your
visual thought power to bring about desired
outcomes.
Flashback
Flashback uses constructive day-
dreaming to strengthen right-brain processes.
When you need more energy or motivation to
get a task done, like studying for a difficult
8. Chapter 1: Know Yourself — Socrates Lesson 5: Left-Brain/Right-Brain
30 Unit 3: Foundations for Success
exam, flashback to a time when you had
plenty of energy and enthusiasm. Perhaps you
were on a hike with friends or washing cars to
earn money for a trip — get in touch with
what you were experiencing in detail. Recall
how you were breathing and moving. Try to
match the feeling of expectancy, of being
connected to a purpose, and of getting on with
things to complete them. When you come out
of your flashback, bring this energy with you
and apply it to the task at hand — studying
for that difficult exam.
Flash Forward
When you desire to accomplish
something, advancing in rank in JROTC,
making the honor roll, or obtaining a
scholarship for college, flash forward to that
event. Imagine precisely how you expect to
experience it. See your name on the honor
roll, and feel the pride swell in your chest.
Feel your breath stop and your entire body
warm up in response to your acceptance
letter. Experience how you will accept
congratulations — with humility from your
superiors and with unrestrained joy from your
closest friends. Visit this scene in your mind
often as you continue to prepare for your
goals. You will be using goal-state
visualization, a very powerful mental
technique to obtain what you want in life.
For best results, use verbal and visual
thinking together and amplify the effect with
strong feelings and emotions (kinesthetic
thought). Say your affirmations aloud and see
yourself acting or feeling the way they
suggest. Once you start your goal-state visual-
izations, monitor your self-talk and make sure
it supports your goals. If something happens
to create discouragement, talk yourself up
with an appropriate affirmation, like:
“There’s nothing to fear but fear itself,” or
“I’ll turn down my fear and turn up my
confidence.” When your verbal thoughts,
mental pictures, and feelings are in harmony
with your goals, you will be activating the
strongest force on earth – a made-up mind.
YOUR PROBLEM-SOLVING STYLE
Would you like to be able to solve
your problems, including those that you
consider to be very difficult, with some form
of a process or style? You probably already
do, but have never thought about it before. In
the activities for this lesson, you will have the
opportunity to complete an exercise that will
test your problem-solving style to see if it is
left or right-brain. Both sides have advantages
and limitations; however, depending upon
the circumstances, one of the sides or styles
will provide the lead for you to make the best
solution. For best results, learn how to
combine the left and the right sides of your
brain to solve problems, especially those very
difficult ones.
CONCLUSION
Knowing about the functions of the
brain is good, but knowing something definite
about your own brain is better. So far you
know that the left and right-brain hemispheres
have specialized functions and, in many
instances, educators emphasize the left-brain
and neglect the right-brain.
During your stages of learning,
growth, and personal development, the world
can and will present different types of
challenges that will place complex demands
on your brain. Know how to use your brain
efficiently. Know your individual brain
preference and your problem-solving style,
then use both sides of your brain to set and
accomplish goals and to tackle those difficult
challenges.
