Forecasting Faces in the Cortex: Comment on ‘High-Level Prediction Signals in a Low-Level Area of the Macaque Face-Processing Hierarchy’, by Schwiedrzik and Freiwald, Neuron (2017)

Although theories of predictive coding in the brain abound, we lack key pieces of neuronal data to support these theories. Recently, Schwiedrzik and Freiwald found neurophysiological evidence for predictive codes throughout the face-processing hierarchy in macaque cortex. We highlight how these data enhance our knowledge of cortical information processing, and the impact of this more broadly.
