Posterior stimulus distributions generated using models that included correlations among the ganglion cells and models that treated the ganglion cells as independent.

<p>The posterior stimulus distributions (matrices) were calculated using three populations of cells: a patch of transient ON cells (<i>n = </i>10 cells), a patch of transient OFF cells (<i>n = </i>11 cells), and a patch that included all the cells recorded in a local region of the retina (<i>n = </i>12 cells). For each population, models were built without correlations (<i>left</i>) and with correlations (<i>right</i>) included. Distances between coupled and uncoupled posteriors were very low: MSE α values were below 0.05, and K-L α values were below 0.1 bits. To avoid data limitation, response distributions for the population were taken directly from the analytical form of the model, as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0053363#pone.0053363-Pillow1" target="_blank">[22]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0053363#pone.0053363-Paninski1" target="_blank">[23]</a>.
