  • Understanding stress and its signals

    The Boston Globe - 06/12/2015

    Lisa Feldman Barrett thinks we’ve long misunderstood how our brains work — and what’s going on when we’re stressed.

    For decades, scientists have assumed that the brain simply responded to signs from the outside world: See tiger coming; get anxious. But instead, Barrett, a Northeastern University professor, argues in a new paper in Nature Reviews Neuroscience that most of our anxieties are triggered not by danger in front of us but the anticipation or fear of it: Worry tiger might appear; get stressed.

    Such a response makes a lot of sense in a world where you may need to run away from fast-moving tigers.
