Table 2.
Mean (standard deviation) of the amplitude (expressed in microvolt) and the latency (expressed in milliseconds) of the three auditory peaks/components (P1, N2, P3) separate for Group (FH− and FH+), Hemisphere (Left and Right) and Condition (STD, DEVF, DEVD). (a) Values corresponding to N2 are reported for the STD condition whereas values corresponding to N2* are reported for the deviant conditions (DEVF and DEVD).
