Ultrasonic vocalizations in male rats following acquisition of copulation-illness associations.
Brief 50-kHz ultrasonic vocalizations are emitted by male rats during copulatory encounters with sexually receptive females. These vocalizations also occurred during pairings with estrous females in male rats whose copulatory behaviors had been associatively inhibited by LiCl-induced aversive contingencies. Longer 22-kHz calls, typically emitted during the postejaculatory refractory period, were not observed in these males. These results demonstrate a dissociation of behaviors that were (mounts, intromissions, and ejaculations) and were not (50-kHz vocalizations) associatively inhibited by LiCl.
