Predictions of phase at fixation onset and EEG response. A, Correlation coefficients (±CI, alpha = 0.001) between the first 200 ms after every fixation onset, separated in seven phase groups (as in Figure 4) and the grand average fERP (gray lines), ongoing-activity model (blue lines), phase-resetting model (red lines), and superposition model (black lines) for NS (left), BK (middle), and GR (right). B, Mean and confidence intervals of the distribution of differences between the actual instantaneous fixation onset phase and predictions of ONG (blue lines), RES (red lines), and SUP (black lines) models for NS (left), BK (middle), and GR (right).
