Fig. 4. Parallel functional subnetworks pervading the face patch system.

Schematic diagram depicting functionally distinct subnetworks operating in parallel within the face processing network. Local cell populations are indicated by neurons within each of the cubes, corresponding to the four face patches recorded in the present study. Coloration indicates functionally distinct classes of neurons. The sharing of distinct functional operations across face patches, and the mixing of these signals locally, were central observations in the present study. The selective long-range connections among functionally similar classes of neurons (colored lines) are hypothesized. An example scene from the movie stimuli is shown at the top.
