Abstract

Kainate or electrolytic lesions were placed unilaterally in the dorsal mesencephalic reticular formation (MRF) or in the deep layers of the superior colliculus (DLSC) on the same side of a unilateral lesion of the medial forebrain bundle with 6-OHDA. Before the lesions the rats turned contralaterally when challenged with 0.25 mg/kg of apomorphine. After lesions of the MRF most rats turned ipsilaterally in response to the same dose of apomorphine. After lesions of the DLSC apomorphine-induced contralateral turning was significantly reduced but not abolished. The results indicate that the MRF and DLSC play a primary role in the expression of turning originated from the striatum.
