In anesthetized rats, mechanical stimulations, the direction and intensity of which could be modified, were applied to the superior incisive while single neurone activities were recorded within the VHM region by means of extracellular glass microelectrodes. The great sensitivity of periodontal receptors to the direction and the intensity of the stimulations was demonstrated at this level. This finding, which is reported here in detail for the first time, suggests that the periodontal afferents might be involved in physiological mechanisms including food intake regulation and osteomorphogenesis.
在麻醉大鼠中，对上门齿施加方向和强度可改变的机械刺激，同时通过细胞外玻璃微电极在腹内侧下丘脑（VHM）区域记录单个神经元的活动。在此水平上证实了牙周感受器对刺激方向和强度具有高度敏感性。这一首次在此详细报道的发现表明，牙周传入神经可能参与包括食物摄入调节和骨形态发生在内的生理机制。
