Split Brain theory

Split Brain theory

For the naysayers, here is the link that illustrates the split brain theory. This theory won Roger Sperry a Nobel Prize. such is the power of the split brain theory.

What is the split brain theory ?

There are 2 distinct functions in the brain – logical and creative. Roger Sperry’s experiments prove that logical (or commonly left hemisphere of the brain. For south paws, it is interchanged) thinking is associated with verbal, analytical, linguistic abilities. Logical thinking is also linear, organized, deductive and inductive. Whereas, the creative part of the brain (or commonly right brain) is associated with non-verbal (body language), synthetic, non-linear, random, emotional abilities. Corpus Callosum is the bridge between the two hemispheres and is the super highway transmitting information back and forth. All the subjects that Roger Sperry worked with, had their corpus callosum severed due to fits and other complicated symptoms.

Now that you have a background, here is my equation

Z (t) = n(t)X + m(t)Y …………………………………………………..(1)

where Z is the total cognitive ability at one point in time. X is 100% logical and Y is 100% illogical or creative.

n(t) represents the fraction of logical ability and m(t) represents the fraction of creative ability, wheret is time.

n(t) + m(t) = 1 ……………………………………………………………(2)

The assumptions in here are that there is no person who’s gifted with 100% logical abilities or 100% creative abilities. The implication of the equation is that there is always a mix of the 2 abilities at any given instant of time. This, of course, is an empirical equation and needs experimental proof. When moving to experimentation, n(t)X can be the amount of neural activity in the logical part of the brain and m(t)Y can be the amount of neural activity in the creative part of the brain. since equation (2) is imposed, individual values for X and Y can be found and plotted as a daily chart or an hourly chart. This can further be mapped on to what kind of activities, a person is involved in.

The situations in which these measurements need to be carried out are

(a) brainstorming

(b) grunt work

(c) day dreaming

(d) watching TV

(e) sports

(f) solving sudoku

(g) humming a tune

(h) face to face interactions with a person, whom you like, whom you detest

(i) addressing an audience of 100 people

Hmmm.. by definition, that is not possible, since Y is not meant for analysis, in its natural state, i think. One thing is certain though. m(t) is going to be linear and n(t) will be a complicated non-linear function.

hi bala – thats a hard-core X-analysis of Z – pls follow this up with a Y-analysis of Z too
