Number of probe sets that differ between developmental stages. Data were analyzed for the number of significant differences in gene expression levels between pairs of time points. Given the unequal distribution of data collection over developmental time, developmental stages separated by 6–8 d were compared for ages less than P14. Probe sets for which expression was not detectable were excluded. The remaining 6653 probe sets were analyzed by one-way ANOVA for significant differences in expression, with a Benjamini–Hochberg false discovery rate (FDR) correction applied post hoc (Benjamini and Hochberg, 1995). The number of genes that were significantly different between time points (p < 0.05) is presented. CTX, Cortex; HPC, hippocampus; HYP, hypothalamus.
