A fMRI, which tracks blood flow in the brain, revealed that when people who have PTSD are reminded of the trauma, they tend to have an underactive prefrontal cortex & an overactive amygdala, which processes fear and emotion.

Indirect spinothalamic pathways. These pathways mediate the affective and arousal components of pain, temperature, and simple tactile sensations. (A) The ascending axons in the paleothalamic tract synapse in the brainstem reticular formation and neurons in midline and intralaminar thalamic nuclei, which then project diffusely to the cerebral cortex including the cingulate gyrus. (B) In the spinoreticular tract, one group of ascending axons projects to the medullary reticular formation, and…

Below the level of the cerebral cortex lies the thalamus, the brain's information relay network. Surrounding the thalamus is a group of structures, the limbic system, which is involved in survival behavior and emotions. Closely linked with the limbic system is the hypothalamus, which has overall control of the autonomic nervous system. The cingulate gyrus is involved in survival behavior. The hippocampus is involved in memory storage.
