This has led people to calling it the "fight, flight, freeze" response, "fight-flight-freeze-fawn" [1] [citation needed] or "fight-flight-faint-or-freeze", among other variants.
The role of the BNST in the acoustic startle reflex may be attributed to specific areas within the nucleus responsible for stress and anxiety responses. [12] Activation of the BNST by certain hormones is thought to promote a startle response [12] The auditory pathway for this response was largely elucidated in rats in the 1980s. [14]
