Neuron pair spatial separation and cortical state correlation. (a) Neuron pair spatial separation for criteria fulfilling correlated clusters (both stationary and ARIMA modelled). Line colour and thickness indicates the number of criteria fulfilling correlated clusters found for pairs of neurons in different layers and barrels and of different E/I-type. Red and blue correspond to E and I neuron types respectively. The numbers in the circles indicate the number of pairs of the same E/I type, layer and barrel. 32 neuron pairs were not added to the plot because at least one of the neurons in the pair lied in a septum (i.e. between barrels). (b) Example of two clusters which do not share a common neuron but have correlated cortical states over trials of a single stimulus. Left and centre: cluster spike times of two clusters coloured by predicted cortical state. Right: predicted cortical states for the two clusters are correlated on trials on which all 4 neurons spike. (c) Top: histograms showing p-values of linear correlation between predicted states of pairs of correlated pairs of neurons, which do not share a common neuron. Inclusion criteria: 15 conjunctive trials. Cases: clustered (redorange), unclustered (green) and clustered and unclustered pooled (blue). Bottom: r-value histograms of linear state correlations (clustered and unclustered pooled). (d) Mean variance explained by each PCA dimension between groups of 4 correlated neurons (on trials that all 4 neurons spiked).
