title: Effective response evoked by microstimulation of thalamus nuclei in patients with tremor.
abstract: 459 microstimulations were done in 10 patients with tremor. The motor evoked response with reduction tremor drive was observed at 38 sites, of which 30 (79%) were noted in ventrointermedialis (vim) nuclei, and 5 (13.2%) in ventrocaudalis (vc) nuclei, 2 in ventroralis posterior (vop) nuclei, 1 in dorsal thalamus (dth). No increased tremor drive response was noted in all the sites. Paresthesia was the most common response (47.1%). Except pain at 1 site in vc nuclei, warm/cold and vertigo were noted in vop, vim, vc nuclei. No responses accounted for 43.8%.
