The synaptic efficacy of inhibitory synapses in tongue protruder motoneurons reinnervating the tongue retractor muscle was studied in cats. We have demonstrated that the percentage magnitude of a short- and a long-lasting inhibitory postsynaptic potential in the inhibitory postsynaptic potentials produced in the tongue protruder motoneurons, whose axons had been cut but allowed to regenerate to make functional contact with the tongue retractor muscles, by lingual nerve or inferior alveolar nerve stimulation, was rearranged to appear like that exhibited by the tongue retractor motoneurons that normally supply that muscle. In addition, the peak amplitude of the summated afterhyperpolarization in a tongue protruder motoneuron on operated cats at nine months axon-union was in the normal range.
在猫身上研究了重新支配舌回缩肌的舌前突运动神经元中抑制性突触的突触效能。我们已经证明，在舌前突运动神经元中产生的抑制性突触后电位中，通过舌神经或下牙槽神经刺激产生的短持续时间和长持续时间抑制性突触后电位的百分比幅度被重新排列，使其看起来类似于正常支配该肌肉的舌回缩运动神经元所表现出的情况。此外，在轴突联合九个月后的手术猫的舌前突运动神经元中，总和后超极化的峰值幅度在正常范围内。
