Table 1.

Total time of exploration of the juveniles and the objects during the training and the testing trial of the social recognition (SRT) and object recognition (ORT) tests, respectively, by TIP39-line mice when previously or not previously exposed to the experiment conditions. Data are presented as Mean ± SEM.
