Fig. 2S – Behavioral phenotype of NOP(+/+) and NOP(−/−) mice exposed to repeated forced swimming sessions. Data are presented as mean ± SEM of the immobility time in the training and test sessions of 9 NOP(+/+) or 10 NOP(−/−) mice/group and retest session of 6 NOP(+/+) or 7 NOP(−/−) mice/group. *P < 0.05 vs. training; ^#P < 0.05 vs. NOP(−/−) mice. Repeated measure two-way ANOVA followed by Tukey's multiple comparisons test.
