Figure 2.
Anatomical and functional community structure. Figure represents a side-to-side presentation of the community structure of the anatomical and strychnine functional macaque brain network. Left, Community structure of the anatomical SC network. Community detection revealed two main communities, including a community overlapping somatosensory and visual regions (blue) and a community overlapping frontal and temporal cortical regions (green). Using a two-step community detection approach (in which the main first-level communities were subject to community detection themselves; see Materials and Methods) revealed the existence of, respectively, three subclusters (light, medium, and dark blue) and two subclusters (light and dark green). Right, Community structure of the stryFC network. First-level community detection revealed three main communities, including a visual–somatosensory community (blue), a lateral frontal–temporal cluster (green), and a medial frontal–temporal cluster (yellow). Two-step community detection revealed three functional subclusters of the visual–somatosensory network, overlapping a visual (dark blue), motor and sensory network (medium and light). In addition, two-step community detection of the lateral frontal–temporal network revealed two subclusters (light and dark green) and three subclusters in the medial frontal–temporal network (light, medium, and dark yellow). Formal statistical testing of the anatomical and functional community structure revealed significant overlap between the two-step community structures (p < 0.001; see Results).
