Cytoarchitectonics, neuronal organization, and the effects of gender on the dendroarchitectonics of neurons in the posterior medial nucleus of the amygdaloid body in rats.
The aim of the present work was to analyze the cytoarchitectonics, neuronal organization, and effects of gender on the dendroarchitectonics of neurons in the posterior medial nucleus of the amygdaloid body of the brain. Studies were performed using 50 mature Wistar rats (25 male, 25 female) using the Nissl and Golgi methods. The nucleus was found to consists of large neurons, which on silver nitrate impregnation had the characteristics typical of long-axon sparsely branched and densely-branched neurons. In males, the dendrites of long-axon sparsely-branched neurons had higher levels of branching, while the dendrites of long-axon densely-branched neurons were longer than in females.
