Brain areas implicated in post-traumatic stress disorder (PTSD). The amygdala, prefrontal cortex, and hippocampus, which are altered structurally and functionally in PTSD, respond differentially to stress-induced adrenal steroids and in turn differentially regulate hypothalamic-pituitary-adrenal (HPA) activity (both positively and negatively). The schematic shows the role of each area in cognitive/emotional function and why it is implicated in PTSD (See Color Plates)

Lateral view of the cerebral cortex showing the principal gyri and sulci. Major structures include the central sulcus and the precentral (primary motor), premotor, and postcentral (primary somatosensory) gyri. Also note the gyri situated rostral to the premotor cortex, including the orbital gyri, which mediate higher order intellectual functions and contribute to the regulation of emotional behavior. Brocas motor speech area and Wernickes area (for reception of speech) are important areas…

TIL it's possible to be declared brain-dead falsely because most physicians look at the brain stem which controls heart and lung functions but not the cortex which coordinates consciousness

And why ptsd sufferers have difficulty with decisions. Attacks can rush blood to one side of your frontal lobe and restrict to the other side, throwing off a lot of various cognitive functions
