ARC and Cognitive impairment: In line with cognitive deficits, both Homer 1a and Arc levels were significantly lower in the brains of OAL SD rats when compared to young animals [Figure 8B, YAL vs. OAL, Two-Way ANOVA, F(1, 20) = 9.63, p = 0.0056, n = 4–8] and LTCR prevented this change [Figure 8B, OAL vs. OCR, Two-Way ANOVA, F(1, 20) = 13.01, p = 0.0018, n = 4–8].
