ERPs elicited by the standard and deviant stimuli in the happy and fearful oddball conditions.

<p>The left occipito-temporal waveform was the average neural activation at electrodes TP7, P7, PO7, CB1, and O1. The right occipito-temporal waveform was obtained from the average of TP8, P8, PO8, CB2, and O2.</p

The topographic maps of vMMN components in both happy and fearful conditions during the time windows of 50–130 ms and 320–450 ms.

vMMN componentsin the fearful (Fig 3A) and happy oddball (Fig 3B) conditions.

<p>The vMMNs in the deviant fearful minus standard fearful condition, and the left frontal waveform was the average neural activation at electrodes of F1, F3, and F5. The right frontal waveform was obtained from F2, F4, and F6. The left occipito-temporal waveform was from TP7, P7, PO7, CB1, and O1. The right occipito-temporal waveform was from TP8, P8, PO8, CB2, and O2.</p
