Reward circuitry in resilience to severe trauma: An fMRI investigation of resilient special forces soldiers

Abstract Enhanced brain reward function could contribute to resilience to trauma. Reward circuitry in active duty, resilient special forces (SF) soldiers was evaluated using functional magnetic resonance imaging during a monetary incentive delay task. Findings in this group of resilient individuals...

More Information
Summary:Abstract Enhanced brain reward function could contribute to resilience to trauma. Reward circuitry in active duty, resilient special forces (SF) soldiers was evaluated using functional magnetic resonance imaging during a monetary incentive delay task. Findings in this group of resilient individuals revealed unique patterns of activation during expectation of reward in the subgenual prefrontal cortex and nucleus accumbens area, regions pivotal to reward processes.
