[Zones of sex dimorphism in the basolateral structures of the amygdaloid complex].

With the aim to reveal zones of sex dimorphism by means of the karyometry method, 25 zones of the basolateral structures have been investigated in the amygdaloid complex. Mature rats (15 males and 10 females) are decapitated, the brain is fixed in 10% neutral formalin, paraffin slices are stained with hematoxylin-eosin and with cresyl violet. A complete idea on topography of the sex dimorphism zones on the territory of the basolateral structures of the amygdaloid complex is given. The zones mentioned are localized predominantly in the posterior part of the amygdaloid complex, making composition of the basolateral and dorsal endopiriform nuclei.
