The current understanding of posttraumatic stress disorder (PTSD) is unique relative to other psychiatric disorders in that there are very clear links between basic affective neuroscience and the diagnostic criteria and treatment of the disorder. Current theories of the causes of PTSD, and gold-standard cognitive behavioral treatments, are grounded in foundational knowledge of fear learning and extinction, emotion regulation, attention, memory, and executive functioning. This conceptual alignment allows for clear translational links from molecular biology to systems neuroscience to healthy human studies and, finally, to the clinic. This chapter will outline a number of such translational links, giving a general overview of how affective neuroscience has informed the current understanding of PTSD and the emerging benefits of these insights.
