Structural and functional differences have been found in male and female brains. They were observed in certain cortical areas, in the hypothalamus and the limbic system. This may be the basis of known differences in endocrine regulation and it may also be linked to behavioral, emotional and cognitive gender differences. Stress response, sexual arousal, parental behavior but also learning and memory depend in part on hormonal regulation which is gender specific. Certain ailments including depression, addiction, obsessive- convulsive- and aggressive disorders are –likely to be controlled by hormonal regulation in the brain. It seems that men and women live in different cognitive worlds that only overlap to a certain extent. This overlap is perhaps the basis for affection. Sexuality is the biological principle of difference.
