Abstract

Sex differences in neuron dendroarchitectonics of the amygdala posterior cortical nucleus of adult rats were described for the first time using the Golgi method. Long-axon sparse-branched neurons in male rats possessed a larger number of primary dendrites, while female rats had long-axon dense-branched neurons with longer dendrites. Injection of testosterone propionate at 1250 µg to females on day 5 after birth resulted in a greater number of primary dendrites of long-axon sparse branched neurons in adults, as compared to that in the control. Dendrites of long-axon sparse-branched neurons became much longer, thus enlarging the dendrite area.
