Electrophysiological recordings were made from functional single fibres teased from the inferior alveolar nerve 12 weeks after nerve section. The force thresholds, adaptation times and conduction velocities of 10 located periodontal ligament mechanoreceptors in 2 cats were recorded and compared with results for normal located receptors from a previous study using similar techniques. The relation of both threshold and the adaptation rate to the position of the reinnervated receptors was statistically significant and similar to the relation for normal units. These results support the hypothesis that the range of response characteristics of periodontal ligament mechanoreceptors depends on their position relative to the tooth's fulcrum.
在神经切断12周后，从下牙槽神经中分离出的功能性单纤维进行电生理记录。记录了2只猫中10个定位的牙周膜机械感受器的力阈值、适应时间和传导速度，并与先前使用类似技术的研究中正常定位感受器的结果进行了比较。阈值和适应率与再支配感受器位置的关系具有统计学意义，且与正常单位的关系相似。这些结果支持了以下假设：牙周膜机械感受器的反应特征范围取决于它们相对于牙齿支点的位置。
