The aim of this study was to establish gender-associated differences in dendroarchitectonics of neurons in posterior cortical nucleus of amygdala and the role of androgens in their formation during the period of sexual differentiation of rat brain. Using Golgi method, it was demonstrated that long-axon sparsely branched neurons had more primary dendrites in males, while long-axon densely branched neurons had greater total dendrite length in females. In mature female rats that received 1250 mg of testosterone propionate on their postnatal day 5, the number of primary dendrites in long-axon sparsely branched neurons was increased, while the dendrites in long-axon densely branched neurons were elongated as compared to those in control females.
