If the amygdala perceives a match to the stimulus, i.e., if the record of experiences in the hippocampus tells the amygdala that it is a fight, flight or freeze situation, then the amygdala triggers the HPA (hypothalamic–pituitary–adrenal) axis and "hijacks" or overtakes rational brain function. [5]
The fight-or-flight or the fight-flight-freeze-or-fawn [1] (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. [2] It was first described by Walter Bradford Cannon in 1915.
In evolutionary psychology, people often speak of the four Fs which are said to be the four basic and most primal drives (motivations or instincts) that animals (including humans) are evolutionarily adapted to have, follow, and achieve: fighting, fleeing, feeding and fucking (a more polite synonym is the word "mating").
The clusters of the amygdala are activated when an individual expresses feelings of fear or aggression. This occurs because the amygdala is the primary structure of the brain responsible for fight or flight response. Anxiety and panic attacks can occur when the amygdala senses environmental stressors that stimulate fight or flight response.
Freezing behavior, also called the freeze response or being petrified, is a reaction to specific stimuli, most commonly observed in prey animals, including humans. [ 1 ] [ 2 ] When a prey animal has been caught and completely overcome by the predator, it may respond by "freezing up/petrification" or in other words by uncontrollably becoming ...

However, when vagal tone is removed, there is little inhibition to the pacemaker, and according to polyvagal theory, rapid mobilization ("fight/flight") can be activated in times of stress, but without having to engage the sympathetic-adrenal system, as activation comes at a severe biological cost.
