Commanding Center of the Human Body

Left Brain and Right Brain

Let’s study the function of Left Brain and Right Brain

The human brain is divided into two hemispheres, left and right, connected by a structure called corpus callosum. The corpus callosum is a wide, flat bundle of neural fibers beneath the cortex connecting the left and right hemispheres and facilitates inter hemispherical communication. It is the largest white matter structure in the brain, consisting of 200- 250 million contra lateral axonal projections.

You can calculate yourself how much percentage you are on left side brain or right side brain by answering the above 40 questions. You score 1 for every answer relevant to you ,. For example if you think in words and is a good speller, you score 1 for each answer for your Left Brain. If not, you score 0. Do the same for your Right Brain also

Suppose you score 20 out of 40 for your Left Brain, the percentage of it’s dominance is 20 / 40×100= 50%

You score 30 out of 40 for your right brain and the percentage of dominance is 30/40×100=75%

The overall performance of any individual depends on how much he uses both sides of his brain or how much each hemisphere dominates in his thinking and functions.

Majority of the people are of mixed dominance, the dominance of each hemisphere will be between 40% and 70%

80% on left and 80% on right= double dominance

Above 60% on left and less than 40% on right= Left Brain dominant

Above 60% on right and less than 40% on left= Right Brain dominant

If dominance in both sides are very close, for example 27% on left and 30% on right, the person may be stuck; he may not be able to take a dicision or move forward. He cannot edit and free write any time . He will not be happy at his job. A double dominant person may also be stuck due to mental overload.

Identifying dominance and promoting both sides of brain in children are very important. The drawing ability of children becomes less after kindergarten because it is less promoted by teachers . They needed math and language spelling which are all left brain functions. Right brain skills in arts and creative thinking are often ignored and it affects brain growth.
