Supplementary Figure 2: The temporal expression pattern of whole genome background genes (WBGs) in BrainSpan data.

WBGs are not differentially expressed across development stages in BrainSpan data (one-sided Wilcoxon rank sum test using medians of expression at prenatal (n = 3) and medians of expression at postnatal (n = 4) stages). The error bar plot shows the median and the 25th and 75th percentiles.
