Simultaneous intracellular recordings were made from the six ipsilateral dorsal longitudinal muscle fibres of Drosophila in stationary flight. The influence of the firing of one motor unit upon the firing of another was analysed by observing the relationship between the interspike interval of a unit and the relative firing times of the other motor units within that interval. The analysis suggests that the influence is insignificant except when one unit would have fired soon after another. Then, a neural interaction occurs that can cause a unit to fire either earlier or later, depending on its firing relationship with the other units. Thus, the observation that no DLM fibre fires soon after another is the result of both a delaying effect and an effect which causes a cell to fire earlier than it normally would have fired.
在果蝇静止飞行时，对其同侧六条背纵肌纤维进行了同步细胞内记录。通过观察一个运动单位的峰间期与该间期内其他运动单位的相对放电时间之间的关系，分析了一个运动单位的放电对另一个运动单位放电的影响。分析表明，这种影响微不足道，除非一个单位紧接着另一个单位放电。此时，会发生神经相互作用，这可能导致一个单位根据其与其他单位的放电关系提前或推迟放电。因此，没有背纵肌纤维紧接着另一条纤维放电这一观察结果，是延迟效应和一种使细胞比正常情况下更早放电的效应共同作用的结果。
