Progressive social withdrawal in trauma-exposed older adolescents and young adults: neurocircuitry predictors

In collaboration with Elizabeth Olson, this project aims to identify the contribution of a specific neural circuit to social withdrawal during the transition to adulthood (ages 16-20) in individuals with a history of interpersonal trauma exposure. Active and passive digital phenotyping metrics will be used to assess social withdrawal over the course of a 12-month follow-up. The hypothesis is that baseline functional connectivity within basolateral amygdala-ventromedial prefrontal cortex-nucleus accumbens circuitry will prospectively predict social withdrawal.
