Assessment of impact of LEV and Sod.Se 0.25 and 0.5 mg/kg alone and in combination on (A) entries in platform zone, (B) time spent in platform zone and (C) total distance travelled during probe session in water maze test. Statistical evaluation was conducted by using one-way ANOVA followed by Tukey’s test and each value in data was represented as mean ± S.E.M (n = 8). **P < 0.01 and ***P < 0.001 control vs PTZ control, #P < 0.05 and ##P < 0.01 diazepam vs PTZ control, aaP < 0.01 LEV vs PTZ control, cP < 0.05 Sod.Se 0.5 vs PTZ control, ddP < 0.01 and dddP < 0.001 LEV + Sod.Se 0.25 vs PTZ, eeeP < 0.001 and eeeeP < 0.0001 LEV + Sod.Se 0.5 vs PTZ control.
