Erythropoietin (EPO) prevents 6-hydroxydopamine (6-OHDA)- induced increases in rotation rates. Data are expressed as the number of net rotations per minute (mean ± SEM) over a 30-min period following apomorphine administration at 21 days after the lesion. *P<0.01 vs. sham-lesion; #P<0.01 vs. 6-OHDA alone, same day (ANOVA); n=7 for each group.
