Neurobiological Models of Posttraumatic Stress Disorder

Abstract

(from the chapter) Focuses on two neurobiological systems that are critical for survival--the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis (HPA). Though most neurobiological research in posttraumatic stress disorder (PTSD) concentrates on these two systems, it is asserted that numerous other neurobiological systems are also involved in acute and chronic responses to stress, although far less is known about them as they relate to PTSD. Several new neurobiological models of PTSD are presented in an attempt to understand the current body of trauma-related neurobiological research.
