Effect of Psidium guajava Linn leaves extract on time spent and number of entries into bright illuminated part in light and dark model transition test. Group I = control group, group II = positive control group, group III = Psidium guajava Linn low strength group, group IV = Psidium guajava Linn high strength group. *p < 0.05, **p < 0.01, ***p < 0.001 vs group I. TSLB = time spent into lighted box and NELB = number of entries into lighted box
