Concerted activity and information coding in the retinal ganglion cells.

In vertebrate visual system, information is firstly processed in retina. With the development of the multi-electrode recording technique, concerted activity has been extensively observed in retinal ganglion cells of different species. However, the role of concerted activity in visual information processing is still unclear and under debating. This article reviews the recent studies focused on concerted activity among retinal ganglion cells, discussing the issues about its category, detection and physiological function.
