Figure 5: A. Performance of mice (n=26) during the MGT in a maze expressed as mean percentage of advantageous choices ± SEM,. Significant difference from chance level: # p<0.05. Significant difference between sessions:* p<0.02. B. Performance of the three subgroups in the MGT (mean percentage of advantageous choices ± SEM). Statistical difference with chance level:* p<0.05. Statistical difference between the subgroups: # p<0.05 (Kruskal Wallis).
