Short-term plasticity in response to masseter nerve stimulation. (A) Examples of the maximum response to the 1st and 2nd stimuli. The interstimulus interval (ISI) was set at 80 ms, 120 ms or 200 ms. Paired-pulse depression was observed. (B) The temporal profiles of optical signal amplitudes in the region of interest in S1 (black) and S2/IOR (red) in (A). Paired-pulse stimulation is indicated by arrows. (C) A faster recovery of the second response in S2/IOR than in S1 at 120 ms ISI (n = 6; *P < 0.05, paired t test).
