Mating behavior in ovariectomized female rats treated with estrogen can be greatly enhanced by subcutaneous injections of progesterone. Application of potassium chloride to the cortex of females previously treated with estrogen can also induce greatly increased sexual receptivity as indicated by the lordosis response. This facilitation of mating behavior by a treatment known to cause functional decortication suggests that mechanisms mediating female mating behavior are under tonic inhibition by an inhibitory system which involves the cerebral cortex.
用雌激素处理过的去卵巢雌性大鼠的交配行为，可通过皮下注射孕酮而大大增强。对先前用雌激素处理过的雌性大鼠的皮层施加氯化钾，也能诱导出如脊柱前凸反应所示的性接受能力大大增强。这种已知会导致功能性去皮质的处理对交配行为的促进作用表明，介导雌性交配行为的机制受到一个涉及大脑皮层的抑制系统的紧张性抑制。
