1. 描述了两种间接测量自由行走蝗虫后胸伸肌（METM9s）力学反应的技术。2. 首先，使用处理过的自由行走（供体）蝗虫制剂的神经图数据来刺激支配受约束（受体）制剂的metm9的神经元。对接收蝗虫的metm9的力学响应进行了等距记录。3. 其次，设计了METM的电子模型，以模拟来自供体蝗虫的处理过的神经图数据激活后的电和机械反应。4. 这两种技术都只能间接估计供体metm9的机械反应，而没有考虑到这些肌肉的张力和长度之间的复杂关系。5. 利用这些技术研究了METM在各种活动（特别是行走、踢腿和跳跃）中的机械反应，并获得了有关兴奋性和抑制性运动神经元功能作用的进一步信息。
1. Two techniques for indirectly measuring the mechanical responses of metathoracic extensor tibiae muscles (METM9s) of free-walking locusts are described. 2. First, processed data from neurograms of free-walking (donor) locust preparations were used to stimulate the neurones innervating the METM9s of restrained (recipient) preparations. The mechanical responses of the METM9s of the recipient locusts were recorded isometrically. 3. Second, an electronic model of the METM was designed to give simulated electrical and mechanical responses following activation with processed neurographic data from donor locusts. 4. Both of these techniques give only an indirect estimate of the mechanical responses of the donor METM9s and do not take into account the complex relationships between tension and length in these muscles. 5. The mechanical responses of the METM during a variety of activities, especially walking, kicking and jumping, have been studied using these techniques and further information on the functional role of excitatory and inhibitory motorneurones has been obtained.
