Blame Rebalance fMRI Feedback Proof-of-concept

Specific aim 1: Demonstrate that anterior temporal lobe (ATL)-septal/subgenual cingulate (SCSR) coupling for guilt can be increased through one session of neurofeedback in the group seeing visual feedback based on increasing correlations during the guilt condition compared with the group seeing visual feedback based on keeping correlations at the same level during the guilt condition. Specific aim 2: Demonstrate that this increase in coupling is selective for guilt relative to indignation. Specific aim 3: Demonstrate that mood is not negatively affected by neurofeedback. Specific aim 4: Explore whether this short intervention decreases self-hate on the Interpersonal Guilt Questionnaire (Portuguese translation) and increases self-esteem on the Rosenberg scale (both show significant correlations with SCSR-ATL coupling across major depressive disorder and control groups in our Manchester study), or if these measures are not available, decreases negative affect on the Positive and Negative Affect Scale.
