Role of correlations in population coding

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