Originally understood as the "fight-or-flight" response in Cannon's research, [3] the state of hyperarousal results in several responses beyond fighting or fleeing. 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.
Index inducer or just inducer predictably induce metabolism via a given pathway and are commonly used in prospective clinical drug-drug interaction studies. [ 2 ] Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates of a given metabolic pathway by ≥80%, ≥50% to <80%, and ≥20% to <50% ...
The concept is mentioned in the 1965 science fiction novel Dune by Frank Herbert as a method to inflict pain with no actual injury. No known real-life analogues of such a device currently exist. However, the effect sometime occurs as a side effect of transcranial magnetic stimulation .

Parasympathetic rebound is a possible delayed (over-)reaction of the parasympathetic nervous system. [1]During intense and/or prolonged stress the opposed sympathetic nervous system via the hormones cortisol and catecholamines (such as adrenaline) suppresses the parasympathetic activities.
Examples of neural inducers are the molecules noggin and chordin. When embryonic ectodermal cells are cultured at low density in the absence of mesodermal cells they undergo neural differentiation (express neural genes), suggesting that neural differentiation is the default fate of ectodermal cells.
Fear is an unpleasant emotion that arises in response to perceived dangers or threats.Fear causes physiological and psychological changes. It may produce behavioral reactions such as mounting an aggressive response or fleeing the threat, commonly known as the fight-or-flight response.
Voodoo death, a term coined by Walter Cannon in 1942 also known as psychogenic death or psychosomatic death, is the phenomenon of sudden death as brought about by a strong emotional shock, such as fear.
