负责动物明显行为的协调运动都涉及运动神经元（MN）中特定的时间活动模式。尽管许多无脊椎动物，特别是节肢动物的神经肌肉接头处存在大量的兴奋性和抑制性影响，但肌肉收缩的启动和控制是由兴奋性和抑制性 MN 的活动引起的。由于 MN 向肌肉传达离散的运动程序，因此在行为表达期间监测其阈下和尖峰放电可以为运动和姿势控制提供最方便的分析。
Coordinated movements responsible for the overt behavior of animals all involve specific temporal patterns of activity in motor neurons (MNs). Although considerable summation of excitatory and inhibitory influences is present at the neuromuscular junctions of many invertebrates, particularly arthropods, initiation and control of muscle contraction are due to activity in excitatory and inhibitory MNs. Because MNs convey discrete programs for movement to the muscles, monitoring of their subthreshold and spike discharges during expression of behavior provides for the most convenient analysis of control of locomotion and posture.
