Biofeedback for Depression

Real-time Biofeedback With 7-Tesla MRI for Treatment of Depression

Previous research has shown that modulation of a brain region in rodents, the ventral tegmental area (VTA), improves depressive symptoms. Human research has also shown that VTA self-modulation using 'biofeedback' is feasible and successful in healthy volunteers. This biofeedback procedure is a type of cognitive training that includes real-time feedback about brain signal levels from the VTA. Our question is whether VTA self-modulation with biofeedback can influence depression symptoms.

Behavioral - Active Biofeedback

The active biofeedback session will be done within the 7T MRI. It will include a pre-training run, 3 training runs, and a post-training run. Each run will be comprised of MOTIVATE and REST trials. During each MOTIVATE trial, subjects will be instructed to "generate a heightened state of motivation". Participants will be encouraged to identify strategies that are personally relevant or useful and to monitor the efficacy of the strategies. Subjects will simultaneously view a progress bar on the sc more on

Behavioral - Sham Biofeedback

The sham biofeedback session resembles the active condition, however, the thermometer seen during the MOTIVATE trials will represent yoked sham values.
