Unconscious reduction of fear through decoded neuro-reinforcement - PROJECT SUMMARY The gold standard treatment for specific phobias is exposure therapy, wherein the individual repeatedly faces the object of their fear. However, for many patients, the level of distress prohibits them from either starting or completing exposure therapy. The objective of this application is to use focal neuro-reinforcement based on decoded fMRI information (from the ventral temporal temporal cortex) to reduce fear responses to feared animal stimuli (e.g., spiders, birds) in individuals with phobias, directly and unconsciously in the brain, without repeatedly consciously exposing participants to their feared stimuli. Because the induced representations are unconscious, participants do not experience negative emotional responses and the procedure is double-blind placebo-controlled, thus providing a level of experimental rigor not afforded to standard psychological therapies. Extending from our pilot data, we are positioned to test the mechanisms and behavioral outcomes of a novel treatment for phobias that at the same time advances our understanding of the role of consciousness in fear responses and their change over time. The specific aims are to: (1) confirm that our method engages the neurobiological target (amygdala reactivity to images of feared animals) in a population of individuals with specific phobias of animals; (2) quantify how changes in amygdala reactivity with neuro-reinforcement mediate changes in behavioral outcomes, as measured by attentional capture, approach/avoidance behavior, or subjective fear ratings, immediately post neuro-reinforcement; (3) assess the longer term effects four weeks after neuro-reinforcement; and (4) explore the impact of three dosage levels of neuro-reinforcement to identify the optimal dosage for future research. If proven effective, the results will inform applications for other fear- related disorders, such as posttraumatic stress disorder, social anxiety disorder and panic disorder.
