Male and Female Brain Development Report from National Institutes of Health. All babies start out with the same number of cells, which over nine months, develop into a complete female baby. The problem occurs when cells are instructed by the little chromosomes to make a male baby instead. Because there are only so many cells to go around, the cells needed to develop a male's reproductive organs have to come from cells already assigned elsewhere in the female. Recent tests have shown that...

these cells are removed from the communications center of the brain, migrate lower in the body and develop into male sexual organs. Now the brain is sort of similar to a full deck of cards, so this means that males are born a few cardsshort, so to speak, and some of their cards are in their shorts.

This difference between the male and female brain manifests itself in various ways. Little girls will tend to play things like house or learn to read. Little boys, however, will tend to do things like placing a bucket over their heads and running into walls.

This basic cognitive difference continues to develop until puberty, When the hormones kick into action and the trouble really begins. After puberty, not only the size of the male and female brains differ, but the center of thought also differs. Women think with their heads. Male thoughts often originate lower in their bodies where their ex-brain cells reside.

Of course, the size of this problem varies from man to man. In some men only a small number of brain cells migrate and they are left with nearly full mental capacity but they tend to be rather dull, sexually speaking. Such men are known in medical terms as "Engineers and Physicists."

Other men suffer larger brain cell relocation. These men are medically referred to as "banjo players."
