Recordings in identified neurons and muscles that mediate crayfish tailflips reveal inhibitory postsynaptic potentials of two distinct durations. Those of long duration are recorded in five classes of cells in the flexion circuit, while those of short duration are recorded in three classes of cells in the extension circuit. The durations of the inhibitory postsynaptic potentials are matched to the durations of inhibition required by the different phases of the behavior.
