The effects of CORT on the expression of ALO AIMs and rotations. A within subjects design was used to examine the effects of CORT (1.25 mg/kg, 2.5 mg/kg, or 3.75 mg/kg) and Vehicle (16% EtOH, 44% propylene glycol, 40% phosphate buffer saline) prior to l-DOPA treatment on AIMs and rotations in L-DOPA-primed rats. Each dose of CORT reduced ALO AIMs compared to Vehicle-treated rats. * Significantly different from Vehicle, p<0.05. Data are expressed as the mean ± 1 SEM.
