NOR test is widely used to test memory, as described previously [36]. Mice were placed in the center of the open field chamber (50 cm × 50 cm × 35 cm). Mice completed an acquisition session in which they were left in an apparatus containing two similar objects. 24 h later, recognition memory was assessed and a different pair of dissimilar objects (a familiar and a novel one, respectively) were presented. Time spent exploring both objects was recorded for 5 min.
