Fig. 1From: Cross-Correlations and Joint Gaussianity in Multivariate Level Crossing ModelsCross-correlations in the Gaussian variables lead to correlations of coincident level crossings. a Spike correlations can arise from common input in a neuronal network. b We consider coincident level crossings arising from two Gaussian processes that share a common latent source. Whenever the voltage crosses a threshold ψ from below a spike is emitted. Spikes are indicated by vertical solid lines. The vertical dotted lines indicate the width of a time bin T used to compute spike counts U [ 0 , T ] V i (ψ), i=1,2Back to article page
