Quando si dice cervello

Until eight weeks old, every fetal brain looks female – female is nature’s default gender setting (…) A huge testosterone surge beginning in the eight week will turn this unisex brain male by killing off some cells in the communication centers and growing more cells in the sex and aggression centers (…) How does this fetal fork in the road affect us ? For one thing because of the larger communication center, this girl will grow up to be more talkative than her brother (…) For another, it defines our innate biological destiny, coloring the lens through which each of us views and engages the world.
Males have double the brain space and processing power devoted to sex as females. Just as women have an eight lane superhighway for processing emotion while men have a small country road, men have O’Hare airport as a hub for processing thoughts about sex whereas women have the airfield nearby that land for small and private planes.
