DOPAMINERGIC NEUROTRANSMISSION AT THE PARAVENTRICULAR NUCLEUS OF HYPOTHALAMUS IN CENTRAL REGULATION OF PENILE ERECTION IN THE RAT

Abstract

Our results demonstrate that application of apomorphine to the paraventricular nucleus of hypothalamus elicited penile erection in the rat. Such an increase in ICP to apomorphine was due mainly to activation of the D2 receptor subtype in the PVN. These observations indicate that PVN may be involved in the central regulation of apomorphine-induced penile erection in the rat.
