Table 2 Description of the duration of the EMG events by the recovery cycle of the Masseter Inhibitory Reflex ( _rc MIR)

Traces/Ch	Area	Duration (S1) (ms)	Duration (S2) (ms)	Δ-Duration S2-S1 (ms)

Duration and difference in duration of various events of the masseter inhibitory reflex. The EMG events correspond to: first silent period (SP1), interposed EMG activity (IA), and the second silent period (SP2) evoked by the conditioning stimulus (S1) and by the test stimulus (S2). Ch1: right masseter and Ch2: left masseter.
