(a) Module 2 of the weighted gene coexpression network analysis demonstrated similar trends to the a priori ZENK expression analysis with (b) eigengene values being higher in response conspecific, parasite, and predator calls and lower in response to the negative controls and heterospecific alarms. Whiskers and boxplots indicate the 10th, 25th, 50th, 75th, and 90th percentile of the respective data (black dots). (c) Boxplots of genes from Module 2 that are considered markers of the song system according to the Zebra Finch Expression Brain Atlas (http://www.zebrafinchatlas.org/).
