title: Acute and chronic behavioural sequelae resulting from intrastriatal injection of an NMDA agonist.
abstract: Unilateral and bilateral injections of cis-2,4-methanoglutamate, a potent and selective NMDA agonist, were made into the striatum of rats. Unilateral injections elicited MK-801-sensitive dose-related increases in contralateral turning, beginning 10-15 min after injection. Bilateral injections elicited typical seizure-like behaviours commencing approximately 80 min postinjection. Forty-eight hours after unilateral injection, and presumably after lesion development, no spontaneous preference for turning was seen. Upon challenge with apomorphine (1 mg/kg SC), ipsilateral turning lasting approximately 60 min was seen. Correlates are drawn between this model and some of the features of Huntington's disease.
