Physiological response to trauma is based on a release of Norepinephrine (NE) a neurotransmitter released from the Locus Coeruleus (LC). NE is released: a) into the hypothalamus, which increases arousal and body defences by the
Behavioural Facilitating System (BFS), activating CNS into the state of emergency; and b) into the Septo-Hippocampal System where mental activities are stored and categorised. When NE is high it increases physiological arousal, that can trigger traumatic memories. Re-experiencing traumas in a form of
nightmares/ and flashbacks cause re-releasing of stress hormones; which reduce memory creating “Black Wholes” (Pitman & Orr, 2007). High level of hormones at the time of trauma plays a role in a
Long Term Potentiation (LTP) and
over-consolidation of traumatic memories. Endogenous stress hormones affect strength of
memory consolidation. NE, endorphin and oxytocins inhibit memory consolidation and create amnesia.
T&T Survivors are aroused being brought to a particular state of mind, back to traumatic experiences, State Dependent Memory in which the traumatic material could be easily accessible and treated.
