RecruitingBehavioural interventionSuicide Specific Rumination in VeteransFew treatments target core features of suicidal thoughts and behaviors in Veterans. Real-time functional magnetic resonance imaging neurofeedback can provide information regarding brain activation associated with suicide-specific rumination, defined as a "repetitive mental fixation on one's suicidal thoughts and intentions." The goal of this feasibility study is for Veterans to learn strategies for modulating activity within brain regions that have been demonstrated to contribute to the maintenance of rumination, as they receive neurofeedback feedback signals from the brain.
