The broad goals of this project are to apply and validate the therapeutic utility of neurofeedback-guided intervention for tinnitus and its associated psychological sufferings. In this project, the investigators will evaluate whether targeted (non-auditory networks) neurofeedback-based training can restore emotional and cognitive health for individuals with bothersome tinnitus. The investigators will also link individual tinnitus scores with objective brain imaging measures before, during, and after the intervention. The investigators will accomplish these goals by using a combined brain imaging and behavioral experimental framework.
Intervention via neurofeedback has shown promising results for many neurological disorders including schizophrenia, post-traumatic stress disorder, ADHD, anxiety and major depressive disorder, with benefits lasting over several weeks after the completion of training ; neurofeedback-guided training has led to participants successfully alter activity in brain regions that mediate emotional response, mood and cognitive control. Because these brain regions and functions are also implicated in bothersome tinnitus, real-time neurofeedback training based on ongoing activity in these targets can poten…

Real-time brain signal acquired through fMRI is used to measure ongoing functional connectivity of relevant brain regions (default mode network), and displayed to participants to mediate targeted regulation.
Real-time brain signal acquired through fMRI on a different participant in the past is displayed to participants under this arm during feedback training.
