At A Stage Of Pre-natal Development Acts, It

at a stage of pre-natal development acts, it appears, in a role of their saviour: getting to nervous cages of potentially man's brain, it, somehow operating on a gene, stimulates - growth of nervous shoots. In own way regulate nervous cages of a female brain and an estrogen. And as nervous cages sensitive to sexual hormones are found not only in , but also in other departments of a brain, it is possible to assume that the sexual differentiation extends on the most different features of nervous activity, so, and behaviour. It has really proved to be true in experiences both on animals, and on people - volunteers. The greatest sexual differences in behaviour at any mammal, as well as at the person while are proved concerning three kinds of activity: sexual reactions, the relation to posterity and aggression... We again and again face differences in work of the female and man's brain, which sexual hormones cause by means of two powerful levers: readjustments of the genetic program at a dawn of a human life and unequal action on different parts of a brain in an adult organism.
