The tergite nerve N6 of the first abdominal segment of the locust Locusta migratoria contains receptor fibers, from the tympanic organ, and hair sensilla as well as motoric axons. The nerve was axotomized in nymphal instars or adults, and the regeneration of nerve fibers was studied. The sensory fibers regrow and regenerate their projection pattern within the central nervous system. They recognize their specific neuropile areas even after entering the ganglion through different pathways. The receptor fibers of the tympanic organ reestablish synaptic connections to auditory interneurons, even though the physiological characteristics of the interneurons are not fully restored. This regenerative capability contrasts with the lack of regeneration of peripheral structures in locusts, but supports the described plasticity in the auditory system of monaural locusts (Lakes, Kalmring, and Engelhard, 1990). The motor fibers do not regenerate nerves innervating muscles of the body wall.
飞蝗（Locusta migratoria）第一腹节的背板神经N6包含来自鼓膜器官的感受纤维、毛形感受器以及运动轴突。在若虫龄期或成虫期对该神经进行轴突切断，并研究神经纤维的再生情况。感觉纤维会重新生长并在中枢神经系统内重新建立其投射模式。即使通过不同途径进入神经节，它们仍能识别其特定的神经纤维网区域。鼓膜器官的感受纤维会重新建立与听觉中间神经元的突触连接，尽管中间神经元的生理特性并未完全恢复。这种再生能力与蝗虫外周结构缺乏再生形成对比，但支持了单耳蝗虫听觉系统中所描述的可塑性（Lakes、Kalmring和Engelhard，1990年）。运动纤维不会再生支配体壁肌肉的神经。
