Abstract

There is substantial neurophysiological evidence from decades of single-cell studies that category and other concept cells exist in both human and animal brains. This indicates that the brain can generalize and create abstract concepts and encode and represent such abstractions using single cells. These single-cell findings cannot be accounted for and explained by the theory of distributed representation and population coding, the dominant theory in the brain sciences. In light of these findings, this paper reexamines the two contending mental representational schemes, localist and distributed, on the basis of computational efficiency, the ability to simultaneously process and activate many different concepts, and the structure for semantic cognition. The evidence for category and concept cells favors localist representation in the brain.
