Fig. 2. Late changes (from baseline to week 8) in relative power in non-responders to escitalopram.

Cold colors show lower relative power at week 8 compared to baseline. Warm colors show higher relative power at week 8 compared to baseline. A, B The x-axis shows frequencies from 0.5 to 50 Hz. The y-axis shows all electrodes from 1 to 58. Image A shows uncorrected t-value map, image B shows significant clusters (p < 0.025, single-tailed, cluster corrected for multiple comparisons). C Topographies illustrate t-values at different frequencies with stars indicating electrodes that belonged to the significant cluster. D Cortical maps depict source-localized regions (p < 0.05, uncorrected) in the frequency band in which the cluster was found at the sensor space level.
