Effects of gabapentin on preference index with the object on the short route and withdrawal thresholds after sham surgery. a Normal and sham rats 2 weeks after surgery received an oral administration of vehicle or gabapentin (GBP, 100 mg/kg) 2 h prior to shuttle maze measurement with the object on the short route. Preference index values are presented as the percentage of counts that animals chose the short route over the total counts. b Withdrawal thresholds in the hind paw ipsilateral to sham surgery were measured prior to the drug administration (baseline) and just after the shuttle maze measurement in normal and sham rats. Data are presented as changes from the baseline
