Fig 2. Heatmap depicting differentially expressed genes between control (light gray) and corticosterone (dark gray) treatments.

Each column is a set of 9 pooled samples, and each row is a gene. Heatmaps are scaled across rows to allow for comparisons of gene expression across individuals. Color indicates log-transformed normalized counts; blue indicates relatively lower expression and red indicates relatively higher expression. Rows and columns are clustered using Euclidean distance.
