Experimental design. Experimental design. Animals were randomized to stimulation groups according to amphetamine rotation results (Amph-Rot) on week 10 after striatal lesion (6-OHDA). The daily 20-min stimulation started on the day of stem cell transplantation after recovery from anesthesia. Amphetamine rotation was retested immediately after the two-week stimulation period and for final assessment three weeks later and was followed by perfusion.
