Brain hemispheres?

Brain Hemispheres.

The brain and its two halfs or hemispheres each identical mirror reverse of the other, that prioritize different tasks that work together. There is a theory involving the Right Left brain theory or vice versa. Each side of the brain controls different types of thinking. And which makes most of us think of those myths that left brained people tend to be creative or even that right brained people are more logical.(Cherry.K 2015) However according to research there is no functioanl difference between the hemispheres and when there are differences in the hemispheres is nominal or very small biased favoring one or the other. If you have a duel CPU computer and you switch the CPUS by putting the left CPU on the right side of the computer and the the riht CPU on the left side would the computer suddenly start using CPU different. However there are not absolute differences between the hemispheres. Of course as media tends to do is selectivly edit facts out to make stories more interesting or as they call it in the busines "SEXY". And thanks to that and some earlier studies a popular myth has evolved that the left hemisphere controls language and no other part of the brain does. Conversly it is widely beleived that the right hemisphere has exclusive control over creatitivty and emotion.(Pinel, P.J, 2012).

Language related abilities provide a good example of laterization and is the best example of all our abilities that are based on cognitive thought. and in various test have shown that know matter which side of the brain is dominant it will not make hyou less smart or less creative if you use one side more then the other. What I mean when refereinf to Brain lateration is the tendancy for various selective processes to be more evolved on one side then the other.(Mosby's Medical Dictionary, 2009)

Research has shown the brain is not as "single minded:" as once thought. we do tend to work better and mor effecient when both halves of the brain are meshing like cogs and sending information back and forth over a bridge called corpus callosum. The corpus callosum is a transverse band of nerve fibers joining the cerebral hemispheres. and is the largest commissure of the brain, connecting the cerebral hemispheres.corpus callosum.(Mosby's Medical Dictionary, 2009).

Seems the misunderstanding began during some experiments on seizure disorders from the work of a man named Roger W. Sperry who even won the Nobel Prize in 1981. His research involved epilepsy and effects. During some experiments he discovered that disconnecting the corpus callosum the communication bridge between the two hemispheres, He found out he could reduce or totally eliminate seizures. However like most brain surgeries there are side effects, Many of the patients found themselves suddenly unable to name objects that were analyzed and processed on the right side of the brain but where still able to name objects that were processed by the left side of the brain. based on this Information Sperry had speculated that language was controlled by the left side of the brain. So no matter how latterized the brain is both work together and thanks to modern evidence neither side as a dictator like control of language or any other tasks no matter which side the brain prioritizes them on. (Cherry,k N.D) to prove this a study was down at the University of Utah with more then 1000 people, The study revealed that even though activity may be higher in some regions and sides of the brain. Both sides of the brain are more less equal in activity.

So it really is useless and pointless to claim some one is right brained or left brained since in the end; the activity equals out and even with portions of the brains damaged the brain will adapt itself by growing alternatives and new short cuts to accomplish the same tasks.

Now the executive functions of our brain are designed to help us manage time, Focus on tasks at hand, The ability to Plan and organize , Critical thinking skills as well as using street smarts or accomplishing things or doing things based on our previous experiences. These are higher order task primary assigned to our frontal lobe. its the Head Office and central office where the CEO lives in our head making executive decisions another words The term “Executive Functions refers to the higher-level cognitive skills you use to control and coordinate your other cognitive abilities and behaviors."(The Regents University of California. 2012). The two main orders that systematically always come from the CEO or Executive portion of the Frontal Lobs is organization, plotting,planning scheming, as well as the working part of our memory, Solving problems as well as being able to think on the fly or cognitive flexibility, out of the box thinking, thinking in abstracts. Acquiring rules and selectively editing out sensory information my labeling it important or unimportant.

The other division of the frontal lobes executive orders are starting and action or not starting one, Self control and emotional regulation to keep us from making rash stupid decisions as well to control our emotions or passions about a subject. Also Regulating internal and eternal stimuli and initiating or preventing a context relevant specific behavior, and finally moral .reasoning and making a decision after processing all the context.."(The Regents University of California. 2012).

The frontal lobe when working properly with all executive departments coordinating with each other it keeps us out of trouble it helps us plan and predict possible future outcomes and selectively tells out what information is important and what information is not important. Instantly and constantly so the rest of our brain can processes the information. It tells us what to prioritize and what not to. Helps us make fully informed choices based on emotions and cognitive processes. It organizes everything for us. from important to least important to ignore things that parent relevant at the moment.

The more aware we are about how we do think, the more aware we are to help some one else understand what is on our mind. which makes communication and group projects a lot more easier. And if we can understand our own motives and how the executive park works as well as the two hemispheres. the more likely we will be able to understand others intentional motives and maybe even predict their future behaviors or outcomes. So there is a necessity in understanding this part of the brain and how it functions and reasons.
