Learn About the Secret Life of the Brain When you feel sad, angry, happy, or anxious, what is really going on inside of you? For centuries, scientists have believed that our emotions come from a part of the brain that is triggered by our environment: the excitement for an upcoming holiday, the fear of losing a loved one, or the anxiety of meeting a deadline for work. These emotions seem uncontrollable and as if they surface automatically from within, eventually finding themselves on the expressions of our faces and in how we carry ourselves. People have long believed this theory about emotions since the days of Plato. But what if everything we know about emotions is wrong? Psychologist and neuroscientist Lisa Feldman Barrett gathers the latest scientific research and evidence to reveal that our common-sense ideas about emotions are long outdated. Instead of emotions being pre-programmed into our brains and bodies, emotions are much more complex than previously thought, and Dr. Barrett aims to prove how our emotions are shaped by our experiences and personal history.
