Attitudes of men differ from those of women. One such cause of this differing attitude is found to be the size of Corpus Callosum in their brain. Corpus Callosum is more developed and bigger in size in females than in men. It is responsible for behaviours relating to arts, sciences and logic respectively.
Corpus Callosum is a part of brain which connects its right and left sides. It is a wide, thick nerve tract, beneath the cerebral cortex in the brain. It is also the largest white matter structure in the human brain, about 10 inches (250 mm) in length and consisting of 200–300 million axonal projections.[Axonal are proteins which are thread-like structures, attached to a nerve cell that send out signals away from the cell. Its size differs in males and females.]
A study on baboons in Kenya has shown that females with a well-developed Corpus Callosum seek egalitarianism while men on the other hand by and large prefer hierarchy or a stable functioning society.
