Figure 4.

Event-related potential CSD responses to low- and high-jitter stimuli from occipital electrodes (P0z, Oz) in controls and patients for the N120 component. The waveforms indicate small but significant differences between the jitter conditions for controls but not for patients. CSD maps at 120 ms show the observed negativity (N120) in controls and patients for the low-jitter condition. The bar graph shows significant differences between the groups in the responses to low- versus high-jitter stimuli. ^*p < 0.05.
