Description
Yuriria Vázquez and co-authors show that the brain's face movement areas work as one network, not two separate circuits, in a 2025 study in macaque monkeys. Textbook teaching splits emotional expressions, run from a medial frontal area, from voluntary movements run by lateral motor areas. Guided by MRI, the team stimulated and recorded from four areas at once while the animals made faces and chewed.
Stimulating one area stirred responses in the others, and during expressions the medial and lateral areas synchronized in the alpha and beta bands. Chewing coupled them at lower frequencies instead. The authors conclude facial control emerges from an interacting sensorimotor network whose coupling shifts with the movement type.
