ERP waveforms and comparison of the results obtained from the audiovisual (AV, left panel), auditory-only (A, middle panel) and visual-only (V, right panel) conditions. a Average ERP waveforms of all healthy subjects recorded from the “Fz”, “Cz”, “Pz” electrodes. The solid and dashed curves correspond to the target and nontarget stimuli, respectively. b Point-wise running t-tests compared target with nontarget responses among all healthy subjects for 30 electrodes. Significant differences were plotted when data points met an alpha criterion of 0.05 with a cluster size greater than seven
