Abstract
Intracerebroventricular administration of calcium severely depressed the locomotor activity of unanesthetized mice, producing ataxic gait and motor incoordination. Pretreatment with pentobarbital (30 mg/kg, IP) twice daily for 2 and 6 days partially reversed this effect of calcium, suggesting that calcium and pentobarbital may in part exert their depressant effect by a similar mechanism.
