Your brain has two sides. And each has a distinctly different way of
|
|||
|
looking at the world.
|
|||
|
|
|||
|
Do you realize that in order for you to read this article, the two
|
|||
|
sides of your brain must do completely different things? The more we
|
|||
|
integrate those two sides, the more integrated we become as people.
|
|||
|
Integration not only increases our ability to solve problems more
|
|||
|
creatively, but to control physical maladies such as epilepsy and migranes,
|
|||
|
replace certain damaged brain functions and even learn to "thin" into the
|
|||
|
future. Even more startling is evidence coming to light that we have
|
|||
|
become a left-brain culture.
|
|||
|
|
|||
|
Your brain's right and left side have distinctly different ways of
|
|||
|
looking at the world. Your two hemispheres are as different from each
|
|||
|
other as, oh, Micheal Wilson and Shirley Maclean. The left brain controls
|
|||
|
the right side of the body (this is reversed in about half of the 15
|
|||
|
percent of the population that is left-handed) and, in essence, is logical
|
|||
|
analytical, judgemental and verbal. It's interested in the bottom line, in
|
|||
|
being efficent. The right brain controls the left side of the body and
|
|||
|
leans more to the creative, the intuitive. It is concerned more with the
|
|||
|
visual and emotional side of life.
|
|||
|
|
|||
|
Most people, if they thought about it, would identify more with
|
|||
|
their left brain. In fact, many of us think we are our left brains. All
|
|||
|
of that non-stop verbalization that goes on in our heads is the dominant
|
|||
|
left brain talking to itself. Our culture- particularly our school system
|
|||
|
with its emphasis on the three Rs (decidedly left-brain territory) -
|
|||
|
effectively represses the intuitive and artistic right brain. If you don't
|
|||
|
believe it, see how far you get at the office with the right brain activity
|
|||
|
of daydreaming.
|
|||
|
|
|||
|
As you read, your left-side is sensibly making connections and
|
|||
|
analysing the meaning of the words, the syntax and other complex relation-
|
|||
|
ships while putting it into a "language" you can understand. Meanwhile,
|
|||
|
the right side is providing emotional and even humerous cues, decoding
|
|||
|
visual information and maintaining an integrated story structure.
|
|||
|
|
|||
|
While all of this is going on, the two sides are constantly
|
|||
|
communicating with each other across a connecting fibre tract called the
|
|||
|
corpus callosum. There is a certain amount of overlap but essentially
|
|||
|
the two hemispheres of the brain are like two different personalities
|
|||
|
that working alone would be somewhat lacking and overspecialized, but
|
|||
|
when functioning together bring different strengths and areas of expertise
|
|||
|
to make an integrated whole.
|
|||
|
|
|||
|
"The primitive cave person probably lived solely in the right
|
|||
|
brain," says Eli Bay, president of Relaxation Response Inc., a Toronto
|
|||
|
organization that teaches people how to relax. "As we gained more control
|
|||
|
over our environment we became more left-brain oriented until it became
|
|||
|
dominant." To prove this, Bay suggests: "Try going to your boss and saying
|
|||
|
"I've got a great hunch." Chances are your boss will say, "Fine, get me
|
|||
|
the logic to back it up."
|
|||
|
|
|||
|
The most creative decision making and problem solving come about
|
|||
|
when both sides bring their various skills to the table: the left brain
|
|||
|
analysing issues, problems and barriers; the right brain generating fresh
|
|||
|
approaches; and the left brain translating the into plans of action.
|
|||
|
|
|||
|
"In a time of vast change like the present, the intuitive side of
|
|||
|
the brain operates so fast it can see what's coming," says Dr. Howard
|
|||
|
Eisenberg, a medical doctor with a degree in psychology who has studied
|
|||
|
hemispheric relationships. "The left brain is too slow, but the right
|
|||
|
can see around corners."
|
|||
|
|
|||
|
Dr. Eisenberg thinks that the preoccupation with the plodding left
|
|||
|
brain is one reason for the analysis paralysis he sees affecting world
|
|||
|
leaders. "Good leaders don't lead by reading polls," he says. "They have
|
|||
|
vision and operate to a certain extent by feel."
|
|||
|
|
|||
|
There are ways of correcting out cultural overbalance. Playing
|
|||
|
video games, for example, automatically flips you over to the right brain
|
|||
|
Bay says. "Any artistic endavour, like music or sculpture, will also do
|
|||
|
it."
|
|||
|
|
|||
|
In her best-selling book "Drawing on the Right Side of the Brain
|
|||
|
(J.P. Tarcher Inc., 1979), Dr. Betty Edwards developed a series of exercises
|
|||
|
designed to help people tap into the right brain, to actually see or process
|
|||
|
visual information, differently. She cites techniques that are as old as
|
|||
|
time, and modern high-tech versions such as biofeedback.
|
|||
|
|
|||
|
An increasing number of medical professionals beieve that being in
|
|||
|
touch with our brain, especially the right half, can help control medical
|
|||
|
problems. For examplem Dr. Eisenberg uses what he calls "imaginal
|
|||
|
thinking" to control everything from migranes to asthma, to high blood
|
|||
|
pressure. "We have found," he says, "that by teaching someone to raise to
|
|||
|
raise their temperature - by imaging they are sunbathing or in a warm bath
|
|||
|
- they can control their circulatory system and terefore the migrane."
|
|||
|
|
|||
|
Knowledge of our two-sided brain began in the mid-1800's when
|
|||
|
French neurologist Paul Broca discovered that injuries to the left side of
|
|||
|
the brain resulted in the loss of speech. Damage to the right side,
|
|||
|
however did not. Doctors speculated over what this meant. Was the brain
|
|||
|
schizophrenically divided and non-communicative?
|
|||
|
|
|||
|
In the early 1960s, Nobel Prize winner Dr. Roger Sperry proved that
|
|||
|
patients who had their corpus callosum severed to try and control epileptic
|
|||
|
seizures could no longer communicate between their hemispheres. The
|
|||
|
struggle can be seen quite clearly in the postoperative period whe the
|
|||
|
patient is asked to do a simple block design. This is a visual, spacial
|
|||
|
task that the left-hand (controlled by the right brain in most of us) can
|
|||
|
do very well but the right hand (controlled by the language-oriented left
|
|||
|
brain) does poorly. The right hand may even intervene to mix up the
|
|||
|
design.
|
|||
|
|
|||
|
Some people with epilepsy can control their seizures by concentrating
|
|||
|
activity on the hemisphere that is not affected. In the case of left lobe
|
|||
|
epilepsy, this can be done by engaging in a right-brain activity such as
|
|||
|
drawing.
|
|||
|
|
|||
|
One intriguing question is why we have two hemispheres at all? "In
|
|||
|
biology you always have the same thing on one side as the other - ears,
|
|||
|
lungs, eyes, kidneys, etc." explains Dr. Patricia De Feudis, director of
|
|||
|
psychology at Credit Valley Hospital in Mississauga, Ont. "But with the
|
|||
|
brain there is more specialization. You can have something going on one
|
|||
|
side and not not be aware of it in the other."
|
|||
|
|
|||
|
Our knowledge of the brain is general is only beginning. We know
|
|||
|
even less about how the hemispheres operate, Getting in touch with how the
|
|||
|
two sides work can only do us good, if just to keep us from walking around
|
|||
|
"half-brained".
