Three Chambered Social Preference Test. a In the sociability phase of the three chambered social preference test, sociability was assessed by measuring the cumulative time spent by the test rat in chamber containing the stranger1 vs. empty cup. There were no differences among the CAE, GE, PGE, and ALM rats in exhibiting preference toward stranger1over the empty setup (*p < 0.05, **p < 0.01, ***p < 0.001 Two-way ANOVA with Tukey ̉s test for the multiple comparisons). b In the social novelty test, the cumulative times spent by a test rat in the chamber containing stranger2 vs. stranger1 were compared. The error bars represent the standard error of the mean. (*p < 0.05, **p < 0.01 Two-way ANOVA with Tukey ̉s test for the multiple comparisons). Number of rats per group: CAE = 10, GE = 11, PGE = 9, ALM = 8
