Values are expressed as means±SEMs (n=8 mice per group). Each mouse was placed on a rubber cylinder after drug injection. Latency to step off the rubber cylinder with the hind paw was recorded. Data were analyzed using one-way ANOVA. No significant difference was observed between drug injected mice and vehicle (aCSF) controls.
