Effect of gabapentin (GBP) on novel object recognition in normal rats. At Day2 of novel object recognition test, animals received an intraperitoneal injection of either saline, GBP (30-100 mg/kg), prazosin (PZS, 1 mg/kg), or their combination 1 hr prior to the test and explored the familiar and novel objects. A) Total exploration time of the two objects. *p<0.05 vs saline only. B) Preference index values are presented as the ratio of the exploration time of the novel object over the total exploration time. *p<0.05 vs saline only. #p<0.05 vs GBP 100 mg/kg only.
