Rats were anesthetized with a 1.0 ml/kg intramuscular injection of a mixture of ketamine (33 mg/ml), xylazine (1.7 mg/ml), and acepromazine (10 mg/ml) and positioned in a Kopf stereotaxic instrument. A total of 12 μg of 6-OHDA (6 μl volume at a concentration of 2 μg/μl dissolved in 0.9% saline containing 0.2 μg/μl ascorbic acid) were infused at a rate of 1.0 μl/minute and allowed to diffuse for 5 minutes before the infusion cannula was slowly retracted. Infusion coordinates were 4.2 mm posterior to bregma, 1.0 mm lateral from midline, and 7.4 mm ventral to dura.
