(1) Visual, auditory and olfactory input were not necessary for the performance of the lordosis reflex by female rats. Since taste is not involved in this behavior, somatosensory input must be sufficient for triggering the lordosis reflex. (2) Surgical cutaneous denervation markedly reduced the frequency and strength of lordosis. The most effective operation denervated the perineum, tailbase, posterior rump and ventral flanks. This pattern of results agrees with film observations and manual stimulation of lordosis. (3) Effects of surgical cutaneous denervation were confirmed in experiments with local anesthesia produced by subcutaneous procaine injections. (4) It is deduced that cutaneous mechanoreceptors in specific regions of hairy skin of the female rat play a crucial role in triggering the lordosis reflex.
(1) 视觉、听觉和嗅觉输入对于雌性大鼠表现出脊柱前凸反射并非必需。由于味觉不参与此行为，体感输入必定足以触发脊柱前凸反射。(2) 手术切断皮肤神经支配显著降低了脊柱前凸的频率和强度。最有效的手术是去除会阴、尾基部、后臀部和腹侧胁腹的神经支配。这一结果模式与脊柱前凸的影片观察和手动刺激结果相符。(3) 通过皮下注射普鲁卡因产生局部麻醉的实验证实了手术切断皮肤神经支配的效果。(4) 由此推断，雌性大鼠多毛皮肤特定区域的皮肤机械感受器在触发脊柱前凸反射中起关键作用。
