Figure 1.

Ability of i.p. administration of I₂-site ligands (2-BFI and BU224) and MAO inhibitors (moclobemide, lazabemide and deprenyl) to elicit ipsiversive rotations in rats bearing a unilateral 6-OHDA lesion. Rotational behaviour was measured for 30 or 60 min post drug or vehicle administration. Data are mean±s.e.m. (n=7). ^*P<0.05 and ^**P<0.01 indicate a statistically significant difference from vehicle using either the Student–Newman–Keuls test after a significant one-way ANOVA or a paired t-test (deprenyl alone).
