Figure 2. Significant VTA Activation and Group Differences Emerged in Post-test following Feedback Training.

Figure 2

(A) VTA ROI defined in an independent sample of 50 participants. Color scale denotes probabilistic weighting of the ROI.

(B) Test run × group interaction plot (p < 0.05) representing percentage signal difference for mean ACTIVATE > COUNT values. Pre-test: no significant activations or group differences. Post-test: VTA Feedback group self-activated the VTA relative to baseline (p < 0.005) and to Control (p < 0.0005) and FF (p < 0.05) groups.
