Abstract

Spatiotemporal codes, such as synchronization of neuronal activity, offer significant computational advantages over traditional rate codes, and our recent simulation studies suggest a role for synchronization in a broad range of cognitive processes, from contour detection to associative memory. We suggest that synchronization mediates Gestalt-based perceptual organization in striate cortex, and that the degree of synchronization represents the perceptual salience of an object. Spatiotemporal coding provides an efficient representation for recognition, and we propose a medial point hypercolumn representation of object shape. Finally, we consider the effects of neuromodulation on synchronization and temporal dynamics in the hippocampal memory system. Together, these processes suggest that the control and coordination of synchronization may be a basic component of many cognitive processes.
