Figure 3From: P300 amplitude is insensitive to working memory load in schizophrenia Grand averages and topographical distribution of the evoked P300 potentials elicited by 1- and 2- back tasks in the CM-ROI. The third column represents the subtraction of the P300 amplitudes at 1- and 2- back conditions for HS and SZ group. The differences were significant for controls (p <0.05), but not for SZ group (p > 0.05). Color bar indicates amplitude (uV).Back to article page
