The original version of this article unfortunately contained a mistake. In the second to the last sentence of the Results section of the Abstract, the sentence should read: “The selective A2A antagonist SCH-58261 (2 mg/kg) also increased step** by 13% and enhanced the therapeutic effect of L-DOPA, whereas the selective A1 antagonist 8-cyclopentyltheophylline (3–7 mg/kg) and A1 agonist N 6-cyclopentyladenosine (0.03–0.2 mg/kg) had no effect.”
