Abstract

Chronic reserpine administration produces persistent oral dyskinesia accompanied by severe dopamine depletion in the caudate-putamen. The present study examined whether these behavioral and neurochemical effects would persist following acute reserpine administration. Acute administration of reserpine (1 mg/kg, s.c.) produced spontaneous oral dyskinesia that persisted above control levels for at least 84 days. Reserpine also produced a 74% depletion of dopamine in the caudate-putamen relative to vehicle treatment at 3 days post-injection, but did not significantly alter dopamine in the caudate-putamen at 84 days post-injection. The finding that reserpine-induced oral dyskinesia persisted despite repletion of dopamine in the caudate-putamen suggests that the persistent neuropathological change underlying this behavior occurs in a neural pathway other than the dopaminergic nigrostriatal pathway.
