Prefrontal-Limbic Brain Circuitry and the Regulation of Emotion
The ability to regulate emotion promotes mental well-being in health and is disrupted in psychopathologies such as post-traumatic stress disorder (PTSD). The prefrontal cortex (PFC)—a region of the brain involved in executive function, behavioral coordination, and cognitive control—is particularly important in implementing the regulation of emotional response. This chapter reviews a decade and a half of neuroscientific research that has made considerable progress in advancing understanding of the neural basis of emotion regulation. This work, conducted in healthy individuals, provides a platform from which to understand the neural basis of emotion dysregulation that characterizes disorders like PTSD. Therefore, the proposed model could serve as a basis for explaining the etiology and/or maintenance of PTSD. The chapter concludes by summarizing the main findings and highlighting areas that need more work, including translation into the clinical domain.
