A region of the brain called the amygdala is responsible for powerful emotions like fear. Now, researchers have found the amygdala may also be to blame for overeating. Cold Spring Harbor Laboratory (CSHL) Professor Bo Li has discovered a group of neurons in the amygdala that drives mice to eat fatty or sugary foods—even when they’re not hungry. Therapeutics targeting these neurons could lead to new treatments for obesity with minimal side effects.
