In the second pathway, cognitive representations of the emotions can be activated in the brain without being directly elicited by a physiological response—called the "as-if body loop". For instance, imagining an encounter with a snake would initiate a similar flight-or-fight response "as-if" you were in that particular situation (albeit perhaps a much weaker one). In other words, the brain can anticipate expected bodily changes, which allows the individual to respond faster to external stimuli without waiting for an event to actually occur.[17]
