Fig. 4From: Neural responses to social decision-making in suicide attempters with mental disordersGrand-average ERP waveforms. (a) ERP difference of grand-average waveform for the electrode average of six electrodes (FPz, Fz, FCz, Cz, CPz, and Pz) between fair proposals (50/50; 60/40) and unfair proposals (80/20; 90/10) in each groups. (b) Amplitude of N1, P2, and FRN in the two conditions were measured in each group. * p < 0.05Back to article page
