This study tests the efficacy of a new behavioral intervention with the goal of reducing spontaneous recovery of threat expectancy in healthy adults. This real-time functional magnetic resonance imaging (fMRI) neurofeedback intervention delivers feedback based on a functional connection between the prefrontal cortex and the hippocampus.
Exposure therapy remains the most effective evidence-based treatment for a variety of anxiety related disorders; however, fear often returns over time. Pavlovian conditioning and extinction serve as a laboratory model for threat learning and exposure therapy, respectively. Studies utilizing these tasks can help uncover why exposure therapy fails to prevent the return of fear in some individuals. Pilot data suggest that there are specific behavioral phenotypes that individuals exhibit during a test of spontaneous recovery following Pavlovian acquisition and extinction. Specifically, some partic…
