Effect of tacrine (TAC; 5 mg/kg po) and rivastigmine (RIVA; 5 mg/kg po) on transfer latency time (TLT) in the PA test to observe the effect on scopolamine (SCO; 3 mg/kg ip) induced impaired (a) acquisition, administered 30 minutes prior to first trial and (b) consolidation, administered five minutes prior to first trial. The maximal time of latency was set at 270s (cutoff time). Values are expressed as mean ± SEM; n = five. *P < 0.05, **P < 0.01 significant increase in TLT on second trial as compared to their respective first trial; student's (paired) ‘t’ test
