From: Vitamin D mitigates age-related cognitive decline through the modulation of pro-inflammatory state and decrease in amyloid burden

  Novel object preference Object-in-place Temporal order memory
  Sample phase Test phase Test phase Test phase
Young CON 49.7 ± 2.21 47.5 ± 3.01 31.1 ± 3.47 33.3 ± 2.51
Young vitamin D 48.2 ± 2.93 45.9 ± 2.99 34.4 ± 3.72 35.2 ± 1.88
Aged CON 47.8 ± 1.97 46.9 ± 3.15 23.7 ± 4.34a 20.1 ± 2.43a
Aged vitamin D 49.3 ± 2.10 47.5 ± 3.07 29.9 ± 4.40 11.9 ± 2.16b
  1. Mean exploration time expressed in seconds(s) during the sample and test phases in the novelty recognition test, and during the test phases in the object-in-place and temporal order memory tests. No significant differences were seen in exploration time during the novelty recognition and object-in-place tests. Meanwhile, aged CON rats showed significantly decrease exploration time in the object-in-place and temporal order memory tests after a time delay.
  2. a P <0.05 (significantly different from the young animal groups). **p <0.01 (significantly different overall).
  3. b P <0.01 (significantly different overall).
