>PACEMAKER FOR PD: There is a surgical procedure which involves implantation of a stimulating electrode into the Thalamus. The stimulator can be turned on and off by the patient using a magnetic switch which is embedded under the skin of the chest. The stimulator provides a high frequency square wave (approx 160 Hz, 11-12V) which helps to alleviate tremor. There are several neurosurgeons who perform this procedure. Itf anyone is interested in literature related to this procedure, please feel free to contact me. ***However, please reply to my personal address rather than the internet list-server.*** [log in to unmask]
