本研究的目的是探讨雌性Long-Evans大鼠的信号行为是否在发情周期中发生变化。气味标记和50 kHz的超声波交配发声，在响应一个离域性经验丰富的男性，在整个周期的频率变化。这两种行为在发情前期/发情早期最高。在周期的每一天记录发声，也记录没有规律周期的雌性动物的发声。相反，气味标记很少观察到在发情周期期间，除了在发情前期/早期发情。这些结果表明，这两种行为。在性感受性时增加，可能有助于协调生殖，并进一步表明在发情周期中观察到的变化的内分泌基础。
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.
