distinct ERP deflections were identified as P1, N1, and N2, particularly over inferior-parietal sites (e.g., see P9 in Figure 1B), and as P3 and LN over posterior sites (e.g., see Pz in Figure 1B). As can be seen, peak latencies and regional maxima of individual ERP deflections varied according to modality. They were, however, comparable across groups, despite patients showing notable reductions in most of these prominent peaks.2
