But Really At Sexual Differentiation Of A Brain

But really at sexual differentiation of a brain only one root hormonal? Really development and work of nervous system are not influenced by radical development of man's and female nervous cages - an unequal set of chromosomes in them? It is a little the signs which are going back to this distinction while it is known, and that their independence of hormones definitively is not proved., For example, two here concern the largest and obscure from the point of view of appointment macroanatomic differences of a female brain: its smaller size and that the bunch of nervous fibres transmitting signals from right in the left hemisphere, at women is wider, than at men. Besides, it is visible, actually genetic features of nervous cages smaller reliability, durability of a man's brain as biological body speaks. For example, through many departments of a female brain proceeds for a time unit on 15 % of more blood, than through corresponding departments man's, - whether the big frequency of strokes is somehow connected with it at men? To thicket there are at men some psychological diseases, developmental anomalies of nervous system.
