amateur interest in neuroscience, nature of consciousness, & the irrational thought processing/response involved in PTSD (the flashback, “a past incident recurring vividly in the mind,” is driven initially by epinephrine, followed by glucocorticoids, most notably cortisol. This happens with lightening speed deep in the limbic system where ‘triggers’ or stressor patterns of association have formed around the traumatic memories. Recognizing and defusing or reducing this neuroendocrine bath, when it is an inappropriate response from the past, is an important key in unlocking the complexity of the PTSD)
