Muscle activity changes after visual motion stimuli (temporal mean of rEMG for the interval of 100-150 ms after the stimulus onset)

Muscle EMG (μV)

(R) 3.1 (1.7)* 31.0 (10.2)* 1.7 (0.6) 1.3 (0.5) 1.2 (0.6) 0.9 (0.8)
(L) 14.3 (8.8) 20.4 (7.2) 1.7 (0.4) 1.4 (0.8) 1.2 (0.6) 0.7 (0.5)

  • The values in parentheses denote SDs of trial variance (n = 30). Asterisks denote statistical significance (t test; p < 0.05) of the difference between the responses in the leftward (L) and rightward (R) stimulus conditions.
