标题： Role of correlations in population coding

摘要： 神经元内部以及神经元之间的尖峰相关性在大脑中是普遍存在的。 例如，交叉相关图在周围区域可能有较大的峰值，在皮层中的峰值较小——但仍然不可忽略——而自相关图几乎总是在多种时间尺度上表现出非平凡的时间结构。 尽管这一点已经为人所知超过四十年，但这些相关性在大脑中起到什么作用仍然不清楚——甚至是否真的起作用也还不清楚。 本章的目标是通过回顾这一主题的一些研究来阐明这个问题。 显示英文摘要

摘要： Correlations among spikes, both on the same neuron and across neurons, are ubiquitous in the brain. For example cross-correlograms can have large peaks, at least in the periphery, and smaller -- but still non-negligible -- ones in cortex, and auto-correlograms almost always exhibit non-trivial temporal structure at a range of timescales. Although this has been known for over forty years, it's still not clear what role these correlations play in the brain -- and, indeed, whether they play any role at all. The goal of this chapter is to shed light on this issue by reviewing some of the work on this subject.
