A release croak is emitted by unreceptive female frogs when they are clasped by males; receptive females are silence. This report investigates the sources of stimuli which initiate and inhibit the release croak of Rana pipiens. Experiment 1 demonstrates that manual clasping of the trunk rather than the legs elicits the croak. Experiment 2 shows that denervation of the skin of the trunk prevents the release call in response to manual stimulation. Experiment 3 confirms that artificial distension of the body with fluid inhibits the release croak in response to manual stimulation. Experiment 4 shows that artifically-distended females, who are not in the normal endocrinological state that accompanies mating, are silent and receptive in response to clasping by sexually-active male frogs. The first two experiments imply that stimulation of the skin of the trunk initiates the release croak; Experiments 3 and 4 suggest that an internal afferent source inhibits the release croak and might mediate an important aspect of receptivity in female frogs.
当未处于接受状态的雌蛙被雄蛙抱住时，它们会发出一种释放叫声；处于接受状态的雌蛙则保持安静。本报告研究了引发和抑制豹蛙释放叫声的刺激源。实验1表明，手动抱住躯干而非腿部会引发叫声。实验2表明，躯干皮肤去神经支配会阻止对手动刺激产生的释放叫声。实验3证实，用液体人工扩张身体会抑制对手动刺激产生的释放叫声。实验4表明，人工扩张的雌蛙，其内分泌状态并非正常交配时的状态，在被性活跃的雄蛙抱住时会保持安静并处于接受状态。前两个实验表明，对躯干皮肤的刺激引发了释放叫声；实验3和实验4表明，内部传入源抑制了释放叫声，并且可能介导了雌蛙接受性的一个重要方面。
