Assignments of genes to onset-age ranges

Age range	Upregulated	Downregulated
Early	115 (26; 22.6%)	92 (17; 18.5%)
Intermediate	56 (15; 26.8%)	37 (10; 27.0%)
Midlife	95 (33; 34.7%*)	60 (16; 26.7%)
Late	105 (27; 25.7%)	98 (18; 18.4%)

Numbers of ARGs assigned to each onset range (Fig. 1) are shown. Parentheses, Numbers and percentages of ARGs within each age range that were also significantly correlated with MWM performance. Note: Percentage of midlife upregulated genes correlated with behavior (34.7%) was significantly higher (*p < 0.05, binomial test) than the percentages in every other upregulated age range.
