The structures and functions of correlations in neural population codes

The collective activity of a population of neurons, beyond the properties of individual cells, is crucial for many brain functions.

In this Review, Panzeri, Moroni, Safaai and Harvey explain how the levels and structures of correlations among the activity of neurons in a population shape ...

Role of correlations in population coding 1 Introduction

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.

Correlations between spike times can also contribute to population codes, for example by facilitating the readout of temporal response patterns in a relative ...

Stimulus-Dependent Correlations and Population Codes

Correlations in the neural response have the potential to both positively and negatively affect the ability of a population to carry information about stimuli.

Information-Limiting Correlations in Large Neural Populations

Understanding the neural code requires understanding how populations of neurons code information. Theoretical models predict that information ...
