A word about the amygdala, which has a privileged role as the brain’s radar for threat: it receives immediate input from our senses, which it scans for safety or danger. If it perceives a threat, the amygdala circuitry triggers the brain’s freeze-fight-or-flight response, a stream of hormones like cortisol and adrenaline that mobilize us for action. The amygdala also responds to anything important to pay attention to, whether we like or dislike it.
