Figure 1.
Top Panel: Grand averaged ERP waveforms time locked to face onset for sad faces presented separately by mother MDD group for contralateral and ipsilateral electrode sites. Bottom Panel: Grand averaged ERP waveforms time locked to face onset for sad faces presented separately by mother MDD group for the contralateral minus ipsilateral difference wave. The highlighted region shows the measurement windows for the N2pc (125–225ms). Waveforms are averaged across electrode pairs (P3/P4, P7/P8, PO3/PO4, PO7/PO8, O1/O2).
