摘要

在脊椎动物的视觉系统中，信息的初级处理发生在视网膜。随着多电极记录技术的发展，视网膜神经节细胞的协同活动在不同物种中被广泛地观察到。然而，协同活动在视觉信息处理中的作用还不清楚，并且存在一定的争议。本文回顾了近些年关于视网膜神经节细胞协同活动的相关研究，对协同活动的分类、检测以及生理功能进行讨论。

Abstract

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.

Key words: retinal ganglion cells; concerted activity; category; cross-correlation; information coding
