FIGURE 1. Contralateral rotations (lesion opposite side) induced by apomorphine (3 mg/kg) 13 days after surgery to induce neurodegeneration. In the graph, the white bar (□) represents the number of contralateral rotations of the animals in the control group (NaCl, 0.9%) and the black bar (■) represents the experimental group (6-OHDA). The vertical lines above each bar indicate the standard error of the mean. The animals whose contralateral rotations were >150 in 60 min were considered sensitive to the neurodegeneration induction model.
