Discrimination ratio in the spontaneous object recognition tasks. Performances in the novelty object test (A) show no significant differences in all groups. However, aged rats showed significant impairment in discriminating between the objects presented in the object-in-place test (B) and temporal order memory test (C) compared to the young animals but vitamin D supplementation ameliorated this cognitive impairment. *P <0.05.
