Relationship of structural to functional connectivity networks. We built a demonstration model consisting of a set of 1,600 modeled neural mean field units arranged on a sphere and engaging in noise-driven spontaneous activity. (A) The anatomical connection pattern, shown only for a few randomly selected neural units, consists of a mix of mostly local (clustered) connections and a few connections made over longer distances. (B) A snapshot and an EEG-like recording trace of the dynamical neuronal activity pattern. Neuronal dynamics is characterized by complex spatial and temporal structure across multiple scales [supporting information (SI) Movie 1]. (C) A functional connectivity network obtained from a thresholded correlation matrix calculated from the dynamics shown in B. In this example, both structural and functional connectivity patterns exhibit small-world attributes.
