Figure 6.

Spike count histograms for five sample populations, all of which share the same heterogeneous lower-order statistics. Panels show the pairwise model (in which G^(m) = 0) and the four different quadrants of triplet interactions (G^(m) = ±0.8). Parameters are taken from the red box in Figure 5 but are reduced from probabilities of spiking patterns to distributions of spike counts. The average pairwise correlation coefficient is ρ = 0.05 and the average difference between the probability of a spike under each stimulus is Δμ = 0.05.
