a well-known term among psychologists
scientists and even modern culture is
left and right brain
you may have heard of these terms
yourself as a means of someone else
describing you maybe someone remarked
upon your amazing math skills telling
you how your left brain thinker or maybe
you painted an awe-inspiring picture and
someone remarked upon your right brain
thinking talents you may have even taken
a facebook test to determine which brain
hemisphere you're more oriented to if
you've stumbled upon this topic on your
own
so what are the terms left brain and
right brain mean oftentimes left brain
is a term used to describe logical
analytical and calculating individuals
for example scientists mathematicians
lawyers accountants and most people who
work with technology are all people who
could be considered left brain on the
other hand or hemisphere right-brained
is often used to describe creative
intuitive emotionally based people for
example artist psychologist graphic and
interior designers songwriters as well
as therapists left and right brain are
both phrases used for labeling but also
for scientific purposes scientists and
neuropsychologist like I studied the two
hemispheres of the brain for over five
decades with a pioneer in the study
Roger will call sperry being given a
nobel prize in 1981 for his work on
split brain research nobelprize.org
summarizes sperrys work as one way
sperry set of these functions was by
examining patients whose hemisphere
connecting nerves have been severed to
alleviate serious epilepsy
by the 1960s he could reveal that the
left hemisphere is more geared towards
abstract and analytical thought
calculation and linguistic ability while
the right hemisphere is more important
for comprehending spatial patterns and
complex sounds like music if left-brain
thinking is considered digital thinking
focusing on topics such as calculation
analysis of the world and right brain
thinking is considered analog thinking
focusing on topics such as art and
creativity you might be wondering if
it's possible for a person to be both
left brain and right brain thinkers or
mentally ambidextrous you might think
you're mentally ambidextrous yourself
neither one hundred percent left brain
nor one hundred percent right brain if
so don't worry there is such a thing as
mental image dexterity in fact most
successful and innovative people
practice using both their left and right
brain hemispheres statistician George EP
box said for the theory practice
adoration to work the scientists must be
as it were mentally ambidextrous
fascinated equally on one hand by
possible meanings theories and tentative
models to be influenced from data and
the practical reality of the world and
all the other with factual implications
deducible from tentative theories models
and hypotheses author eff scott
Fitzgerald says the test of a first-rate
intelligence is the ability to hold two
opposing ideas in the mind at the same
time and still retain the ability to
function while boxes idea focuses on the
mental ambidexterity of the scientists
and Fitzgerald's idea focuses on two
sides of an opposing system working
together practicing using both
hemispheres of the brain is an important
trait to possess for everyday life
Larry Smith of the interval group.com
rights mental ambidexterity is not just
about holding two opposing ideas in the
mind at once it is instead about
thinking and behaving in two
diametrically opposing ways depending on
the situation
this is most often manifested in the
operational excellence perspective and
the business transformation perspective
the ability to be mentally ambidextrous
is to be able to accommodate both the
efficiency perspective and the
experimentation perspective and the
no-win and how to behave using the
appropriate perspectives basically you
have to be good at using science and art
smith gives a great example of how to
use both brain hemispheres and business
but his example can also be translated
in daily life both brain hemispheres can
be used to create balance and Accord in
relationships business and career
personal perspective problem-solving as
well as even health by practicing duo
hemisphere thinking you can become a
creative problem solver an analytical
designer a passionate calculator or even
able to balance when you use
emotionally-charged thinking and
practice logical thinking even if you
are skeptical to whether or not the
brain hemispheres have any significance
on your mental process or if you fully
believe that left and right brain
thinking is scientifically provable it
is always important and imperative in
every situation to act appropriately you
can always improve your reactivity and
also your strength even if you're not
basing your behavior and mental process
of a hemisphere chart even after
learning all of this information on the
left and right brain hemispheres you
might be asking yourself is the opposing
brain hemisphere concept really exist
how is it possible that one side of the
brain thinks a certain way while the
other behaviors completely different is
it actually possible for one side of my
brain to be dominant over the other
some people say the idea of the left
brain and right brain thinking is a myth
Christopher one Jack of LiveScience
rights now scientists at the University
of Utah have debunked the myth
with analysis of more than 1,000 brains
they found no evidence that people
preferentially use their left or right
brain all of the study participants and
no doubt the scientists are using their
entire brain equally throughout the
course of the experiment the preference
to use one brain region more than others
for certain functions which science is
called lateralization is indeed real the
lead author dr. Jeff Anderson director
of the fMRI neurosurgical mapping
service at the University of Utah for
example speech emanates from the left
side of the brain for most right-handed
people this is not imply though that
great riders or speakers use the left
side of the brain more than the right
for that one side is Richard neurons
so what does this mean for Roger sperrys
groundbreaking work on the brain
hemispheres well it might mean that his
research is outdated considering the
revolution of the mind and society as a
whole since Perry's original experiment
was conducted in the nineteen sixties it
wouldn't be too surprising that humans
now use both sides of the brain equally
perhaps at one time when people and life
for far less complex it was easier and
made sense to put people into mental
categories and labels each generation is
born with different genes different
cells and overtime and nearly completely
different genetic and chemical makeup
their brains and mental process being no
exception
considering experience work was
conducted over 50 years ago it might be
time for a scientific update let's put
it into perspective like this
neuroscience was first emerging as a
major field studies in the 1960s
experiments and theories such as sperrys
being conducted and executed we knew
very little about the brain and
neuroscience and neuropsychology began
emerging being met with many questions
however we currently know more about the
brain than ever before neuroscientist
are now able to change the emotional
makeup of memories we understand a lot
more about how and why the brain works
and we are even able to conduct
experiments show that individuals may or
may not use both sides of the brain
equally times ideas and theories are
constantly changing and the brain
hemispheres are no exception to this
universal rule so maybe rather than a
personal characteristics being
categorized into their dominant brain
hemisphere we can simply see these as
personality traits is more likely than
not that individuals are merely more
logic oriented or creativity focused
rather than using one hemisphere of the
brain only this evidence can also be
found in taking a look at the brain
hemisphere model chart some and most
people possess a mixture of the traits
characteristics and skills listed on the
left and right brain charts it's very
rare and often fictional to find a
person who can
clearly fits into one category of the
brain hemisphere some people are
talented at math but also very good at
creating artistic pieces other people
are very analytical but can also use an
imagination to varying extents
cherishing a council he'll calm confirms
this idea writing everyone should
understand the personality types
associated with the terminology left
brain and right brain and how they
relate to him or her personally
however we just don't see patterns where
the hole left brain network is more
connected or the whole right brain
network is more connected some people it
may be that personality types have
nothing to do with the hemisphere being
more active stronger or more connected
said researcher Jared nielsen the
general verdict is this in the 1960s
sperrys research may have been and most
likely was true however in modern times
the idea of left and right brain
thinking has been debunked it is now a
matter of opinion and what you wish to
believe the fact of the matter is
science neuroscience and psychology as a
whole are consistently coming up with
new ideas facts and information
scientifically what may be true today
could be proven incorrect tomorrow hope
