Theory of cortical function.

Proceedings of the National Academy of Sciences of the United States of America Feb 6, 2017
Most models of sensory processing in the brain have a feedforward architecture in which each stage comprises simple linear filtering operations and nonlinearities. Models of this form have been used to explain a wide range of neurophysiological and p...
