The investigators received funding for a near-identical FDA regulated trial before opening this study to enrollment - the IRB requested closure of the unfunded pilot trial to create a new submission.

This is a single-arm, open-label feasibility study. A maximum of 15 participants will be enrolled. All participants will undergo a novel neurofeedback intervention, targeting down-regulation of deep limbic structures, specifically the amygdalae. Participants will complete 12 neurofeedback sessions delivered twice weekly over 6 consecutive weeks. The intervention will be delivered via the PRISM platform.
