Elevated plus maze test. i) Representative tracksheets of elevated plus maze test. Graphs showing alterations in (ii) time spent in open arm, (iii) number of entries in open arm, (iv) time spent in close arm and (v) number of entries in close arm in elevated plus maze following exposure to monotony stress, PCPA administration and novel object intervention during isolation. Values are expressed as mean ± SEM. ‘a’ denotes p ≤ 0.01 when compared to PHNO group, ‘b’ denotes p ≤ 0.01 when compared to PH, ‘c’ denotes p ≤ 0.01 when compared to PHNOPCPA group, ‘d’ denotes p ≤ 0.01 when compared to PHPCPA group and ‘e’ denotes p ≤ 0.01 when compared to SH group and ‘f’ denotes p ≤ 0.01 when compared with SHNO group.
