Fig. 1From: Evoked potentials and behavioral performance during different states of brain arousalGrand average waveforms (a) and mean amplitudes (b) for standard components in the ignored condition. The standard P1, N1, P2 and N300 are presented at Cz electrode in EEG-vigilance stages A, B1 and B2/3&C (N = 38). The significant results of multiple comparisons are marked with asterisk (*p < .05; **p < .01; ***p < .001; each p value is Bonferroni corrected). The corresponding effect sizes for Cohen’s dz are represented in parentheses Back to article page
