Decorrelation and efficient coding by retinal ganglion cells

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 c...

Neural Coding Analysis in Retinal Ganglion Cells Using Information Theory

Information Theory is used for analyzing the neural code of retinal ganglion cells. This approximation may quantify the amount of information transmitted by the whole population, versus single cells. The redundancy inherent in the code may be determined by obtaining the information bits of increasing cells datasets and by analyzing the relation between the joint information compared with the ad...

Concerted signaling by retinal ganglion cells.

To analyze the rules that govern communication between eye and brain, visual responses were recorded from an intact salamander retina. Parallel observation of many retinal ganglion cells with a microelectrode array showed that nearby neurons often fired synchronously, with spike delays of less than 10 milliseconds. The frequency of such synchronous spikes exceeded the correlation expected from ...

Retinal Ganglion Cells

Segments from adult fish and rat retinae were explanted on myelinmarker expressing oligodendrocytes derived from the regenerating goldfish optic nerve. Fish axons grew in high density and even rat retinal axons regenerated to considerable length on the surface of the fish oligodendrocytes, suggesting that this type of fish glia has axon-growth promoting surface components that exert their influ...
