Abstract
Evoked potentials were recorded from the forearm area of the anterior cerebellar lobe following stimulation of the following ipsilateral brain stem points: spinal trigeminal tract and nucleus, restiform body, inferior olive, ventrolateral region containing olivocerebellar fibers, lateral reticular nucleus, fasciculus cuneatus, external cuneate nucleus, and the dorsal spinocerebellar tract. Active contralateral brain stem points were the inferior olive, fasciculi gracilis and cuneatus and the dorsal posterior perihypoglossal region. Electrolytic lesions in the ventral spinocerebellar tract, external cuneate nuclei or spino-olivocerebellar system had no effect upon the cerebellar localized forearm response to superficial radial nerve stimulation. Localized destruction of the ipsilateral lateral reticular nucleus completely eliminated this cerebellar response.Keywords
