Journal of Neuroscience: Art Work asTitle Page

The title page shows immunomicrographs from decreasingly clustered neuronal networks projected onto globes. Together they symbolize the transition from modular to global connectivity and from “insular” to comprehensive activation of the network as modularity decreases.

 In the corresponding article in the same issue, Samora Okujeni and Ulrich Egert demonstrate that scale-free dynamics preferentially emerges in networks with moderate modularity, which provides first experimental support for theoretical predictions that such network structures facilitate self-organized criticality in neuronal networks.
