Figure 7. Protein-level interactions between song production and learning-related module genes in juvenile Area X.

A protein interaction network plot using the STRING database between genes in learning-related (darkred, green, greenyellow) and song production (black, blue, darkgreen, orange, royalblue) modules. Nodes are scaled by number of connections. Edge width is determined by scaling the STRING protein interaction confidence score for the two nodes by the product of each node’s intramodular connectivity. Interactions within learning or song production modules are omitted for clarity.
