Materials and Methods: For this study, 24
rats were taken and divided into four groups (six in each). First group served as the control
group, second and the third group as BG treated groups (400 and 800 mg/kg, p. o.) and
the fourth group as standard drug (piracetam) 500 mg/kg, p.o. treated group. Learning and
memory, activity of BG was evaluated in normal rats, using elevated maze plus and passive
