The functional neuro-anatomy of the human response to fear: A brief review
نویسنده
چکیده
Being exposed to fear signals makes us feel threatened and prompts us to prepare an adaptive response. Fear perception and appropriate behavioural responses are crucial for environmental adaptation and survival of species. Sympathetic activation after fear perception triggers the fight or flight (or freeze) reaction, which allows an attempt to meet the stressful situation in an adaptive manner. Furthermore, the transmission or sharing of fear within social groups may represent a defensive mechanism for many species.
