<p>Schematic depiction of the generative model and proposed Granger sensori-behavioral functional taxonomy.</p>

The spiking activity of networked neurons is influenced by latent endogenous processes (red traces) and an exogenous stimulus (blue traces), with black arrows indicating GC connectivity between neurons.

The blue and green arrows, respectively, show the effects of the stimulus on neurons and neurons on behavior, in the sense of Granger’s temporal predictability. Bottom: our proposed inverse solution and G-taxonomy; following network parameter estimation, statistical testing, and false discovery rate control, we define three categories of neurons, namely Granger Stimulus, Granger Intersection, and Granger Behavior.</p>
