| Abstract: | "The purpose of the present study was to investigate whether the signaling behaviors of female Long-Evans rats varies over the estrous cycle. Scent marking and 50-kHz ultrasonic mating vocalizations, in response to a devocalized sexually experienced male, changed in frequency across the cycle, both behaviors being highest at proestrus/early estrus. Vocalizations were recorded on every day of the cycle and also in females showing no regular cycles. In contrast, scent marking was rarely observed during the estrous cycle except at proestrus/early estrus. These results suggest that both behaviors, which increase around the time of sexual receptivity, may help to coordinate reproduction and further suggest an endocrine basis for the changes observed over the estrous cycle" |
