CPZ and Anxiety: Upon treatment with BHB, the distance moved (total distance and distance traveled in the central area, ***p < 0.001 vs. control group), and time spent in the central area (***p < 0.001 vs. control group) were both increased in BHB + CPZ and CPZ + BHB groups (Figures 3B–D), suggesting that BHB pre-intervention or simultaneous intervention can decrease the anxiety-like behavior of CPZ-fed mice.
