* Indicates significant difference from Group I, # indicates significant difference from Group II and $ indicates significant difference from Group III. n = 4 for Group I, 8 for Group II, 10 for Group III, and 66 for Group IV. Pair-wise comparison was performed using Mann-Whitney test. *, #, $ p ≤ 0.05, ## p ≤ 0.01, ***, ###, $$$ p ≤ 0.001. Group I includes rats displaying “high anxiety and low activity”, Group II includes rats showing “low anxiety and medium activity”, Group III includes rats displaying “low anxiety and high activity”, and Group IV includes rats showing “medium anxiety and high activity”.
