T1-weighted spoiled gradient (SPGR) brain MRI scans in the stereotactic coronal plane in four rhesus monkeys after surgical placement of electrolytic lesions (the focal areas of hypointensity) targeting the ventral part of the dentate nuclei in each cerebellar hemisphere. Rostral planes of section in the four Cases are on the left, and caudal planes are on the right. The right cerebellum is shown on the right. Slice thickness is 1 mm.
