Figure 6:

A spline-interpolated topographical distribution of test-retest correlation coefficients of alpha-band power is shown for corresponding conditions across the two sessions. The left panel shows conditions preceding the relaxation breathing/guided imagery activity. White and yellow indicate poor test-retest reliability, particularly for the eyes-open condition. Pale orange-to-red indicate moderate-to-excellent reliability, as in the eyes-closed condition pre-activity. The right panel shows the corresponding topographies for post-activity blocks. Alpha at all sensors had moderate to excellent retest reliability after pain management activity, as shown on the same scale.
