Abstract

We have examined the information contained in the coordination of groups of cells in the primary visual cortex of the cat recorded with a 5 × 5 microelectrode array. When testing small differences (10°) are discriminated easily on the basis of the independent spike counts. We conclude that synchrony provides a reliable mechanism to transmit fine structure of visual information and offers an efficient cooperative neural code that we have only begun to explore.
