From: Exploration of auditory P50 gating in schizophrenia by way of difference waves
Grand average of stimulus one, stimulus two and difference wave at the central frontal channel in the two groups. The grand average auditory evoked potentials at the frontal channel (Fz) in the control group (black line, N = 24) and the schizophrenia spectrum patients (red line, N = 17). From top the stimulus one (S1) waveform, the stimulus two (S2) waveform, and the difference wave (S1–S2) in the groups. At bottom the difference wave of the electro-oculogram (EOGd) Arrowhead points at P50d.
