Network construction identifies distinct modules of co-expressed genes.

<p>The network was constructed using gene expression data of 92 medicated schizophrenia cases and 78 controls (dataset 1). The dendrogram was produced by average linkage hierarchical clustering of genes using 1-topological overlap as dissimilarity measure (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0039498#s4" target="_blank">methods</a> section). Modules of co-expressed genes were assigned colors corresponding to the branches indicated by the horizontal bar beneath the dendrogram.
