2.4. Novelty-Suppressed Feeding Test

The Novelty-Suppressed Feeding (NSF) test was performed as previously described [40]. Briefly, in the center of a large rectangular arena (60 × 40 × 15 cm), filled with the wooden bedding, a regular food pellet was placed on a white paper platform. Before of the test, mice were food deprived for 24 h. An individual mouse was positioned in a corner and the latency to eat the pellet was scored. Immediately after the first bite, mice were transferred to their home cage and the quantity of food eaten during 5 min was weighed (home cage food consumption).
