Stimulus-locked, reference-free current source density (CSD) [μV/cm2] waveforms for auditory stimuli (averaged across old and new items) comparing 20 patients and 20 controls at all 31 sites (lines as in Figure 1). Distinct CSD components included central N1 and N2 sinks (approximate peak latencies 120 and 420 ms at C3 for controls), central P2 (200 ms at Cz) and lateral-posterior P3 sources (620 ms at P7).
