Neural Synchrony Links Sensorimotor Cortices in a Network for Facial Motor Control.

Summary: Have you ever wondered how your brain controls your facial expressions? For a long time, scientists thought we had two completely separate brain paths for this: one for emotional faces (like smiling when you are happy) and one for faces we make on purpose (like winking). But a new study using monkeys shows this old idea is wrong! By looking at brain waves and scanning the monkeys' brains, researchers found that these two areas actually talk to each other a lot. They work together as one big team to help us make all kinds of facial expressions.
