Single motor units were isolated in intact cats, by microstimulation through chronically implanted microwires in the L5 ventral roots. Motor unit axonal and mechanical properties were obtained by stimulus-triggered averaging the signals from an implanted femoral nerve recording cuff and patellar tendon force transducer. All unit types were sampled with this technique, and it was also possible to stimulate in isolation an axon whose ventral root spike was recorded during treadmill locomotion. A new technique was described, spike-triggered microstimulation, for verifying the identity of a stimulated and a recorded axon.
通过长期植入L5腹侧神经根的微丝进行微刺激，在完整的猫身上分离出单个运动单位。通过对植入的股神经记录袖带和髌腱力传感器的信号进行刺激触发平均，获得运动单位的轴突和力学特性。使用该技术对所有类型的运动单位进行采样，并且还能够在跑步机运动期间，单独刺激一条其腹侧根动作电位被记录的轴突。本文描述了一种新技术——动作电位触发微刺激，用于验证被刺激轴突和被记录轴突的一致性。
