Triplet correlations among similarly tuned cells impact population coding
Which statistical features of spiking activity matter for how stimuli are encoded in neural populations? A vast body of work has explored how firing rates in individual cells and correlations in the spikes of cell pairs impact coding. Recent experiments have shown evidence for the existence of higher-order spiking correlations, which describe simultaneous firing in triplets and larger ensembles...
متن کاملImpact of triplet correlations on neural population codes
Which statistical features of spiking activity matter for how stimuli are encoded in neural populations? A vast body of work has explored how firing rates in individual cells and correlations in the spikes of cell pairs impact coding. But little is known about how higher-order correlations, which describe simultaneous firing in triplets and larger ensembles of cells, impact encoded stimulus inf...
متن کاملPopulation Coding with Motion Energy Filters: The Impact of Correlations
The codes obtained from the responses of large populations of neurons are known as population codes. Several studies have shown that the amount of information conveyed by such codes, and the format of this information, is highly dependent on the pattern of correlations. However, very little is known about the impact of response correlations (as found in actual cortical circuits) on neural codin...
متن کاملRole of correlations in population coding
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 (Rodieck, 1967; Mastronarde, 1983a; Mastronarde, 1983b; Nirenberg et al., 2001; Dan et al., 1998), and smaller – but still non-negligible – ones in cortex (see Cohen and Kohn, 2011 for a review), and auto-correlograms ...
متن کاملCorrelations, feature-binding and population coding in primary visual cortex.
To test the hypothesis that correlated neuronal activity serves as the neuronal code for visual feature binding, we applied information theory techniques to multiunit activity recorded from pairs of V1 recording sites in anaesthetised cats while presenting either single or separate bar stimuli. We quantified the roles of firing rates of individual channels and of cross-correlations between reco...
