Scientists in the lab of Winrich Freiwald have shed new light on the underpinnings of human speech by identifying neural circuitry in the brains of monkeys that could represent a common evolutionary origin for social communication. As reported in the journal Neuron, these circuits are involved in face recognition, facial expression, and emotion. And they may very well have given rise to our singular capacity for speech.

Working with rhesus macaque monkeys, Freiwald had previously identified neural networks responsible for recognizing faces—networks that closely resemble ones found in the human brain.
