细胞内记录来自蝗虫、血吸虫和脊索虫的后胸共同抑制神经元的胞体。胞体被2-5 mV的波幅尖峰被动侵袭。研究了常用缓蚀剂对各种不同输入的响应。通过对神经元胞体的同时记录，测试了常见的抑制性和兴奋性运动神经元与相同或拮抗肌肉之间的偶联。未发现低阻力或突触介导的偶联。供应身体两侧肌肉的两个共同的抑制性神经元的胞体一起位于中线神经节的腹面(图6)。他们没有以任何方式结合在一起。向普通抑制剂中注入氯化钴表明，它有一棵广泛而复杂的树突树，局限于神经节的同侧半部(图8)。一支分支伸入胸间神经节。不同动物的树突分支模式有差异(图10)。
SummaryIntracellular recordings were made from the soma of the metathoracic common inhibitory neuron of the locustsSchistocerca andChortoicetes. The soma is passively invaded by a spike of 2–5 mV in amplitude. The response of the common inhibitor to a variety of different inputs was studied. Tests for coupling between the common inhibitory and excitatory motoneurons to the same or antagonistic muscles were made by simultaneous recordings from pairs of neuron somata. No low resistance or synaptically mediated coupling was found. The somata of the two common inhibitory neurons which supply muscles on opposite sides of the body lie together on the ventral surface of the ganglion on the mid-line (Fig. 6). They are not coupled in any way. Cobalt chloride injected into the common inhibitor has shown it to have an extensive and complex dendritic tree confined to the ipsilateral half of the ganglion (Fig. 8). A single branch extends into the mesothoracic ganglion. There are differences in the branching patterns of the dendrites in different animals (Fig. 10).
