“…Based on grand waveforms and previous investigations (e.g., DeCicco et al, 2012;Foti & Hajcak, 2008), the mean LPP amplitudes were evaluated as the average activity in the three regions of posterior (Pz, P3, P4, Oz, O1, O2), central (Cz, C3, C4, CPz, CP3, CP4), and anterior (Fz, F3, F4, FCz, FC3, FC4) and calculated separately by the three time windows of early (400-1,000 msec), middle (1,000-2,000 msec), and late (2,000-3,000 msec).…”
