Light-dark transition test. GEPR-3s displayed reduced time spent in the light compartment [^*F_{(1, 40)} = 10.1, P = 0.003] and males spend less time in the light than females [F_{(1, 40)} = 22.8, P < 0.0001]. Animals were initially placed in the light side of the apparatus; total test time was 5 min. Pairwise comparisons indicated a sex effect in both strains (Ps < 0.05, Holm-Sidak corrected), and the strain difference was significant for females, but not males (P < 0.05, Holm-Sidak corrected). Figures show mean and standard error of the mean.
