| Research Abstract |
Our functional imaging study of cases with essential tremor revealed that the ascending motor-related sensory impulses go via the spino-thalamic pathway, pass through the most lateral part of thalamic VIM nucleus and project to the bottom of central sulcus corresponding to cortical 3a and 4 area. Our surgical study showed that the little difference of the location and size of therapeutic thalamic Vim lesion markedly affected the development and change of symptoms. Also that of thalamic CVD lesion in patients with central post-stroke pain accompanying hemiparesis definitely affected the conduction of the ascending motor-related sensory impulses on the thalamus. It was suggested that individual meticulous functional study was needed to undestand the cerebral pathophysiological conditions in applicating the functional reconstruction surgery to the patients and unfortunately there existed a difficult case for applicating this treatment.
