Motifs in the wiring diagram. (A) These four subgraphs that appear in the connectome have specific biological functions. Although the biological significance of these motifs was previously hypothesized, enumerating all subgraphs can identify additional essential motifs. (B) Here, we see six isomorphic subgraphs of size 3. The node colors do not represent labels but rather correspond to the bijection that preserves edges. The boxed subgraph is the canonical form where the string (bottom right) corresponding to the adjacency matrix (bottom left) is minimized.
