[Comparative biochemistry of the triune brain].

Abstract

The contribution of the phylogenesis to the study of the functional organisation of brain constitutes an essential component in the integration of the current data regarding the knowledge of the central nervous system. The three evolutive structures evidenced by McLean allowed manifestation of a biological diversity particularly expressed in the neommamalian brain. Studying this biological diversity constitutes one of the field of comparative biochemistry. In this article, the authors attempt to characterize evolution through the study of GABA-receptors.
