STRUCTURAL AND FUNCTIONAL ORGANIZATION AND GENOARCHITECTONICS OF THE MEDIAL AMYGDALOID NUCLEUS

Abstract

The review summarizes for the first time the literature of the last decade describing cytoarchitectonics, neural organization, electron-microscopic characteristics of the neurons of the medial nucleus (ME) of the corpus amygdaloides (CA), and the representation of neurotransmitter systems in it. The data are provided that indicate the involvement of ME in functional processes associated with instinctive behavior - feeding, aggressive-defensive and reproductive, which are implemented with the participation of the hypothalamus. The data on the genoarchitecture of the nucleus shows that ME is formed as a derivative of subpallial (anterior peduncular region), pallial (ventral pallium) and extratelenthephalic (preoptic region) progenitor domains. The multiplicity of and differences in the histogenetic domains involved in the formation of ME give evidence of complex multi-stage rearrangements that occurred in CA during the evolution of the brain.
