Face Values

Understanding vision remains one of the grand challenges that neuroscientists confront. One key aspect of this problem relates to the way the brain identifies faces, the most important social emblem. Neurons in defined sections of the cerebral cortex, called face patches, are dedicated to recognizing faces. Uncovering the organization of the face-patch system served as a prelude to deducing the underlying computations that the brain makes to identify faces. This neural code may serve as a Rosetta stone for representing other objects besides faces.
