Microinjection of muscimol into the superior colliculus of urethane-anesthetized rats mimics the effects of 6-OHDA lesions. A, Each record is the average of 10 rectified OOemg responses to two stimuli delivered to the right cornea (R Cornea) with an interstimulus interval of 400 msec. Theleft traces are from the right OOemg (Direct OOemg), and right traces are from the left OOemg (Consensual OOemg). Top traces are direct and consensual blinks evoked before muscimol microinjection (Pre Muscimol), and the bottom traces are blinks evoked after a 0.01 μg microinjection of muscimol into the left superior colliculus (Post Muscimol). B, Relative direct OOemg amplitude evoked by SO stimulation before (Pre, striped bars) and after (Post, solid bars) muscimol microinjection into the SC contralateral to the corneal stimulus. The bars are means of nine microinjections normalized to the mean preinjection OOemg amplitude of all animals, and the error bars are 1 SEM.
