title: Intranigral methionine sulfoximine induces turning behaviour in the rat.
abstract: Unilateral infusion of methionine sulfoximine (MSO) into the substantia nigra of the rat induced contralateral rotations appearing progressively after a delay of about 100 min. The rotations were maximally antagonized by picrotoxin and bicuculline intraperitoneally injected at approximately 50-80 min after the intranigral infusion of MSO. Contraversive turning behaviour was absent after intranigral infusion of MSO in unilaterally 6-hydroxydopamine-lesioned rats.
