Dynamic network inference from monkey V4 data.

<p>In this experiment, a 90° grating on a screen was presented to the monkey for 2s (light gray shaded areas). 1004 trials were recorded, and binary spike trains were constructed with bin width of 10 ms. <b>A</b> Top: Exemplary spiking data (<i>N</i> = 45). Bottom: Empirical probability (black) of observing a spike over time and spike probability of the fitted model (green). <b>B</b> Top: The fitted network at three different time points, before, during, and after stimulation. Edges with significantly non-zero are displayed (as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005309#pcbi.1005309.g001" target="_blank">Fig 1</a>). Bottom: The mean of smoothed MAP estimates for and (dark gray line). The shaded area is the mean ± standard deviation. <b>C</b> Credible intervals of macroscopic measures of the network over time obtained from the smoothed estimates of the model (light color). Dark shaded area corresponds to the credible intervals of the estimates for trial shuffled data.
