Figure 4

Variability of time and subject of WPLI response to oddball stimulus. A) WPLI averages taken over 10 distinct 30 s intervals to highlight the time varying nature of the WPLI event-locked response. The first 30 s of the trial were averaged in interval 1 and the last 30 seconds in interval 10. Red vertical lines indicate the onset of the oddball stimulus in each interval. Subject 1 is the same subject used in previous figures. B,C) Channel pair WPLI responses for selected intervals and over all time demonstrating the variability of WPLI responses across subjects.
