Possible hormonal interaction for eliciting courtship behavior in the male newt, Cynops pyrrhogaster

Highlights • Four factors act centrally to elicit the courtship behavior of the male newt. • AVT and PRL enhance the function of 7α-OH PREG neurons. • 7α-OH PREG increases incidence of the behavior. • PRL and androgen contribute to the activation of the AVT system. • AVT specifically enhances the fr...
