Figure 9. Central sites, Group data, average reference: Statistically significant ERSP plot differences between stimulus conditions as a function of hemisphere.

Figure 9

Eyes, Mouth and Control conditions appear in top, middle and bottom panels, respectively. For Eyes, the ERSP plot from Eyes-Away has been subtracted from Eyes-Direct. For Mouth, Mouth-Open was subtracted from Mouth-Closed, and for the Control, Control 2 was subtracted from Control 1. Frequency (Hz) is displayed as a function of time (ms). Differential power in decibels for ERSP activity is depicted by the color calibration bar at the right of the figure. Warm colors depict relative EEG signal power increases, and cool colors indicate relative EEG signal power decreases. Grey areas in the plot indicate regions where the differences between conditions were not significant.
