[The amygdaloid complex in the sexual differentiation of the brain].

Presents the results of many-year research of the systemic and structural functional arrangement of the amygdaloid complex of the rat brain as the neuroendocrine center involved in the regulation of the reproductive processes. Special attention was paid to the sexual dependence of the structural and functional arrangement of this section of the brain. The amygdaloid complex was found involved in the critical period of brain development in the processes of sexual differentiation, this fact resulting in sexual dimorphism, that manifests in sexual differences of this complex structural and functional arrangement and its histophysiology. Sexual dimorphism areas in each of the neuronal ensembles of the rat amygdaloid complexes singled out by the authors, are described.
