[Paleoamygdala as the Neuroendocrine Center of Regulation of Reproductive Processis].

Abstract

This review contains modern information about the representation of serotoninergic system in the Amygdala with detailed characteristics of the localization of serotonine fibers and serotonine receptors in nuclear and paleocortical structures. These data indicate the joint participation of serotonine and sex steroids in the regulation of the neuroedocrine function of Amygdala, which have a modulating effect on the secretion and release gonadotropine centers and sexual behavior centers in the hypothalamic area of the brain. The survey also gives information about changes in the exchange of serotonine in the Amygdala's structures in the process of alimentary, maternal, aggressive-defensive and emotional behavior. Systematizes the data on the role of serotonin and sex steroids in the mechanisms involved in the stress response of Amygdala, and its participation in the formation of mood, emotions and the genesis of depression. Presented data on changes in morphometric characteristics of brain structures caused by polymorphic variants of genes of serotoninergic systems and data on the asymmetry of its content.
