本文研究了蟑螂运动神经元在挤压5号神经后再生到完整的间胸腿的神经肌肉联系的模式。虽然一些解剖学上确定的运动神经元与其正确的目标肌肉重新建立了功能连接，但一些相同的运动神经元和其他运动神经元被发现对不适当的肌肉进行功能神经支配。肌肉，在某些情况下，单独的纤维，往往同时受到正确的和外来的运动神经元的支配。神经支配错误的频率随着术后时间的增加而减少，尽管一些错误持续到检查的最新阶段(227天)。
The pattern of neuromuscular connections of cockroach motor neurons regenerating to an intact mesothoracic leg after crushing nerve 5 has been investigated. While a number of anatomically identified motor neurons re‐established functional connections with their correct target muscles, some of the same and other motor neurons were found to functionally innervate inappropriate muscles. Muscles, and in some cases individual fibres, were often simultaneously innervated by both correct and foreign motor neurons. The frequency of innervation errors decreased with increasing post‐operative times, although some errors persisted to the latest stages examined (227 days).
