Diazepam was anxiolytic. (A) 2 mg/kg dose of diazepam increased center time during open field testing and (B) increased the percentage of time spent in the open arms of the elevated plus maze relative to vehicle. No significant changes were observed at the 1 mg/kg dose in either open field or elevated plus maze testing (p>0.05). *p<0.05, **p<0.01. Bar graphs and error bars indicate mean ± SEM.
