The Position and Extent of the Human Dentate Nucleus
There have been several accounts in the literature in recent years of the relief of spasticity and of movement disorders by surgical destruction of all or part of the dentate nucleus (Toth 1961, Heimburger 1967, Zervas et al. 1967, Siegfried et al. 1970). Thalamic lesions have been known to alleviate rigidity and involuntary movement, but in most, if not all cases, a thalamic lesion fails to improve spasticity and some types of involuntary movement, especially choreoathetosis (Gortvai 1964). The failure of thalamotomy in such cases provides one of the driving forces in the search for another neuronal system as the target for therapeutic stereotactic surgery.
