Abstract/OtherAbstract:
In a Sprague-Dawley-derived line of rats, selectively bred to establish a high incidence of spontaneous yawning behavior, the simultaneous and systematic monitoring of yawning and penile erections, during observation periods of one hour, demonstrates a linear correlation between these two behavioral patterns. Dose-effect curves of yawning and penile erections elicited by apomorphine and bromocriptine, and their inhibition by metoclopramide are quite similar. These results strongly suggest that yawning and penile erection are subject to some common regulating and modulating mechanisms, one of which seems to involve dopaminergic pathways.
