Fig. 4. Effects of moxonidine in spontaneous alternation rodent assay.

A significant difference was found between mice exposed to scopolamine and naïve mice (saline) in which scopolamine-exposed mice showed decrease in spontaneous alterations. Treatment with donepezil and atomoxetine rescued this effect. Moxonidine also rescued this effect in mice in a dose-dependent manner, showing significantly higher spontaneous alterations in mice treated with 0.3 mg/kg and 1 mg/kg treatment but no significant differences were observed between mice treated with 0.1 mg/kg moxonidine compared to scopolamine treated mice. * denote significant differences.
