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.
