Background: Social cognitive impairments, specifically in mentalizing and emotion recognition, are common and debilitating symptoms of posttraumatic stress disorder (PTSD). Despite this, little is known about the neurobiology of these impairments, as there are currently no published neuroimaging investigations of social inference in PTSD.

Methods: Trauma-exposed veterans with and without PTSD (n = 20 each) performed the Why/How social inference task during functional magnetic resonance imaging (fMRI).

Article Synopsis
  • The study investigates the role of inflammation and neural responses to rewards in understanding sex differences in depression.
  • Using an experimental inflammatory challenge, female participants showed decreased brain activity in response to anticipated rewards when inflammation was induced, unlike male participants.
  • The findings suggest that inflammation could help explain why incidence rates of depression vary between sexes, particularly highlighting the different neural responses based on gender.
