Spatial learning and memory ability in mice via Morris water maze. (a) Escape latency; (b) Average speed; (c) Number of platform-site crossovers; (d) Time in the target quadrant; (e) Distance in the target quadrant; (f) Tracks of probe trial. CON: control; VDD: vitamin D-deficient diet; VDD + FA/VB₁₂: vitamin D-deficient diet plus folic acid/vitamin B₁₂ supplement; VDD + VD: vitamin D-deficient diet plus vitamin D supplement; VDD + VD-FA/VB₁₂: vitamin D-deficient diet plus vitamin D and folic acid/vitamin B₁₂. All data are presented as the mean ± SEM (n = 8). A two-sided p < 0.05 was considered statistically significant.
