Note. Mean amplitudes (µV) are indicated with SE values in parentheses. S1–4: values for standard stimuli; D: values for deviant stimuli; Dcontrol: values for deviant- control stimuli; n: number of epochs. The time windows adopted are 214–264 ms for monkey A and 220–270 ms for monkey Y (See Methods).
