Neural transection of the dorsal extrahypothalamic descending afferents by means of an L-shaped Halász knife at the anterior commissure (anterior roof deafferentation. ARD) markedly potentiated the display of lordosis and soliciting behaviors. Bilateral lesions of the ventromedial hypothalamus (VMH) attenuated lordotic activity in the ARD sham females but not in the ARD females. In contrast, the lesions in the pontine central gray concurrently with ARD effectively inhibited the display of lordosis but not soliciting behaviors. These results suggest that the VMH may not be a primary focus of the dorsal extrahypothalamic inhibitory influence on lordosis. The influence of this inhibitory system seems to be dominant in regulating the expression of lordosis behavior, compared to that of the hypothalamic lordosis facilitating system. Furthermore, the dorsal extrahypothalamic inhibitors influence which could be removed by ARD must be modified by the neural mechanism in the lower brain stem in which the pontine central gray may be actively involved.
通过在前连合处使用L形哈拉斯刀切断下丘脑背侧下丘脑外下行传入神经（前顶盖去传入，ARD），显著增强了脊柱前凸和求偶行为的表现。腹内侧下丘脑（VMH）的双侧损伤减弱了ARD假手术雌性动物的脊柱前凸活动，但对ARD雌性动物没有影响。相反，与ARD同时进行的脑桥中央灰质损伤有效地抑制了脊柱前凸的表现，但没有抑制求偶行为。这些结果表明，VMH可能不是下丘脑背侧对脊柱前凸抑制影响的主要焦点。与下丘脑脊柱前凸促进系统相比，这种抑制系统在调节脊柱前凸行为表达方面的影响似乎占主导地位。此外，可通过ARD去除的下丘脑背侧抑制性影响必须由脑桥中央灰质可能积极参与的低位脑干神经机制进行调节。
