Figure 7:

A spline-interpolated topographical distribution of test-retest correlation coefficients of alpha-band power is shown for corresponding conditions across the two sessions. The top panel shows the first block of the pain management activity for the respective sessions, which included relaxation breathing, guided imagery, and positive words (positive words were analyzed separately). White and yellow indicate poor test-retest reliability. Pale orange-to-red indicate moderate-to-excellent reliability, as in the guided-imagery block, which had mostly excellent retest reliability across sensors. The bottom panel shows the topographies for the positive-words block, which showed mostly better-than-moderate reliability across sensors.
