在猫三叉神经感觉主核（Vms）记录到周期性机械敏感单位（PM单位），PM单位的感受野从下颌到上颌的背腹侧方向排列。大多数PM单位是对犬齿有反应的单齿单位。它们具有方向选择性，对施加在牙齿上的压力有持续的反应。刺激尖牙时，上下颌PM单位的最佳刺激方向是单一的，主要是颈内侧或头外侧方向。大多数单位的犬齿刺激阈值强度小于0.05 N。这些结果表明，PM单位在VMS的响应特性相当接近的初级传入神经所产生的牙周机械感受器。
SummaryPeriodontal mechanosensitive units (PM units) were recorded from the trigeminal main sensory nucleus (Vms) of the cat. The receptive fields of PM units were arranged from mandibular to maxillary divisions dorso-ventrally. The majority of PM units were single tooth units responsive to the canine tooth. They were directionally selective and had sustained responses to pressure applied to the tooth. The optimal stimulus direction of maxillary and mandibular PM units when the canine tooth was stimulated was single and it was oriented predominantly in the caudio-medial or rostrolateral direction. The threshold intensity of canine tooth stimulation was less than 0.05 N in most of the units. These findings indicate that the response properties of PM units in the Vms resemble fairly closely those of the primary afferent nerves arising from the periodontal mechanoreceptors.
