Tremendous progress has been made in basic neuroscience recent decades. One area that especially successful is research on how the brain detects and responds to threats. Such studies have demonstrated comparable patterns of brain-behavior relationships underlying threat processing across a range mammalian species, including humans. This would seem be an ideal body information for advancing our understanding disorders which altered key factor, namely, fear anxiety disorders. But not led significant improvements clinical practice. The authors propose order take advantage this gain, conceptual reframing needed.

Upon increasing levels of threat, animals activate qualitatively different defensive modes, including freezing and active fight-or-flight reactions. Whereas is a form behavioural inhibition accompanied by parasympathetically dominated heart rate deceleration, reactions are associated with sympathetically driven acceleration. Despite the potential relevance for human stress-coping, its phenomenology neurobiological underpinnings remain largely unexplored in humans. Studies rodents have shown that depends on amygdala projections to brainstem (periaqueductal grey). Recent neuroimaging studies humans indicated similar brain regions may be involved freezing. In addition, flexibly shifting between modes critical adequate stress-coping relies fronto-amygdala connections. This review paper presents model detailing these neural mechanisms shift action. Freezing not passive state but rather parasympathetic brake motor system, relevant perception action preparation. Study responses advance insights into stress-related psychopathologies characterized rigidity stress The therefore concludes research agenda stimulate translational animal–human this emerging field responses. article part themed issue ‘Movement suppression: stopping stillness’.
