Abstract

It might be imagined that the recently observed synchronizations among neurons of cat visual cortex are epiphenomena or side products of cellular properties with no causal significance for visual signal processing. Our working hypothesis, on the contrary, assumes that synchronization of neural activities forms the basis of a flexible mechanism for feature linking in sensory systems. Specified for the visual system, the hypothesis states that the receptive field properties of visual neurons in different parts ol the visual system can be linked into a perceptual whole by synchronizing the activities of those neurons that are activated by a coherent visual stimulus. We further assume that synchronization among the activities in distributed neural assemblies is internally enhanced or even generated via a specific linking (association) network that connects corresponding and noncorresponding locations of the cortical representations of visual space.
