Following creation of a unilateral circumscribed lesion in a portion of a cat substantia nigra pars reticulata by microinfusion of ibotenic acid, circling movements toward the contralateral side of the lesion appeared within 2 days and disappeared a few days later. After recovery, the circling movements reappeared when the cats were decerebrated at the premammillary and precollicular level, suggesting that brain centers rostral to the decerebration participate in compensating the circling movements.
