一种沙漠蝗虫（Schistocera gregaria）的制剂已经开发出来，在这种制剂中，可以使用已识别的神经元，同时仍然允许一些行为。共26个运动神经元的后腿进行了研究，单独的，并在不同的对，无论是通过直接刺激，并通过记录在自发活动和各种反射动作。通过将电流传递到它们的胞体并将诱发的胞体尖峰与肌肉中的细胞外或细胞内记录的事件相关联来识别运动神经元。还记录了肌肉的张力，并刺激运动轴突以引起胞体中的逆向尖峰。epsp和ipsp都可以在胞体的记录中清楚地看到;尖峰只作为电紧张传导的残余物出现。胞体表现出很少或没有产电。据推测，冲动是在一个区域发起的，该区域暂时与神经元的运动轴突出现的区域一致。整合发生在神经毛段，与索马作为一个平行的RC元素。数据获得的协同和拮抗运动神经元的协调和对相同的肌肉的慢和快神经元的兴奋模式的中央机制。
A preparation of the desert locust,Schistocera gregaria, has been developed, in which it was possible to work with identified neurons while still allowing some behavior. A total of 26 motorneurons to the hind leg were studied singly, and in various pairs, both by direct stimulation, and by recording during spontaneous activity and various reflex actions. Motorneurons were identified by passing current into their somata and correlating the evoked somata spikes with extracellularly or intracellularly recorded events in the muscles. Tension of the muscle was also recorded and motor axons were stimulated to evoke antidromic spikes in the somata. Both epsp's and ipsp's can be seen clearly in recordings from the somata; spikes appear as electrotonically conducted remnants only. Somata exhibited little or no electrogenesis. It is inferred that impulses are initiated in a zone tentatively identified with the region of emergence of the motor axon from the neuropil. Integration occurs in the neuropilar segment, with the soma serving as a parallel RC element. Data was obtained on the central mechanisms of coordination of synergistic and antagonistic motorneurons and on the modes of excitation of slow and fast neurons to the same muscles.
