Abstrakt: Summary Unilateral intranigral administration of the oxidative metabolites of 1-methyl-4-pheny1-1,2,3,6-tetrahydropyridine (MPTP), 1-methyi-4-phenyl-dihydropyridine (MPDP+) or l-methyl-4-phenylpyridine (MPP+) produced dose-dependently a depletion of dopamine in the ipsilateral striatum of rats two weeks following treatment.d- Amphetamine and apomorphine induced circling toward the lesioned side in these unilaterally treated animals. No contralateral circling behavior was observed after challenging with apomorphine. This dopamine lesioning effect of MPP+ was not blocked by pretreatment of animals with a dopamine uptake blocker, GBR 12909.
