lesions of intrastriatal neurons ( using kainic acid local injections ) and of corticostriatal afferent fibers led 2-3 weeks later to large decreases ( 63 and 30 % , respectively ) in striatal [ 3h ] ampa binding , whereas selective lesion of the nigrostriatal dopaminergic pathway ( using nigral injection of 6-hydroxy-dopamine ) was without any influence .
