Microstimulation for stereotactic neurosurgery.
840 microstimulations were done in 21 patients with movement disorders and chronic pain. Paresthesia was the most common response and occurred in 53.3% of cell responses, since the present study was performed mainly in the nucleus ventrocaudalis (Vc). Sensorimotor responses were noted in 8.3%, mainly from the Vc, but they were also noted from the nuclei intermedialis (Vim) and oralis posterior (Vop). Motor responses were noted in 3.6%, mainly from the Vim and Vop nuclei. Pain sensation was elicited in 3.8% and no response was seen in 22.6% of cells after stimulation.
