Nonlinear relations between post‐traumatic stress symptoms and electrocortical reactivity during emotional face processing in combat‐exposed veterans

Combat‐related post‐traumatic stress symptoms (PTSS) are prevalent among recently deployed veterans, making identification of biomarkers of PTSS in this population a public health priority. Given the link between threat processing neurobiology and PTSS, the threat‐related late positive potential (LPP), an ERP reflective of attentional processing sensitive to emotion and its regulation, may have utility as a cost‐effective biomarker. Existing...
