Fight-or-flight response

The "fight-or-flight response", also called the "fight-or-flight-or-freeze response", the "fright, fight or flight response", "hyperarousal" or the "acute stress response", was first described by Walter Cannon in 1929.

This response was later recognized as the first stage of a general adaptation syndrome that regulates stress responses among vertebrates and other organisms.
