Hubs of the small-world network are located in the central SCN. (A) Inferred networks are shown overlaid on SCN tissue shape (gray). Connections between nodes are particularly dense in core regions and individual connections are difficult to distinguish. The third ventricle is oriented at the top of each network. Strong functional connections between halves indicate that the core regions communicate to establish consistent phase to entrain the shell. Cells which have no or few functional connections are preferentially located in the outer SCN shell regions. (B) Heatmaps of node degree [color $\propto \text{log}\left(k\right)$] distribution show that hubs of the small-world network are preferentially located in SCN core regions.
