Note[edit]

It seems like two different procedures are described Pallidotomy is a procedure where a tiny electrical probe is placed in the globus pallidus (one of the basal ganglia of the brain), which is then heated to 80 degrees celsius for 60 s, to destroy a small area of brain cells.

and

Liquid nitrogen is then circulated inside the probe. The cold probe destroys the targeted brain tissue.

If I am right, it should be made more clearly that the treatment can be EITHER heating OR cooling. --Algotr (talk) 20:58, 25 March 2009 (UTC)[reply]

Virtually all pallidotomies were performed with RF ablation, with the workhorse instrument from Radionics. Liquid nitrogen cooling is virtually nonexistent. While imaging (both CT and MRI) help to localize the appropriate site for either a lesion or a DBS electrode implant, these techniques do not have the spacial resolution to find the grain-of-rice sized target. This is why the patient is awake: so he or she can communicate with the surgeon or more usually neurologist who is continually monitoring the patient for motor or vision issues. These responses allow the surgeon to hit the right target without off-target effects. Electrophysiological recording and stimulation are also employed to enhance target identification.

Focused ultrasound[edit]

I know that the Focused Ultrasound Foundation is doing pallidotomies to treat Parkinson's disease. https://fusfoundation.org Pigkeeper (talk) 12:19, 17 August 2019 (UTC)[reply]

Removed information[edit]

The article mentioned the following unreferenced detail regarding heating the globus pallidus:

This is heated to 80 °C (176 °F) for 60 seconds

This has been removed from the article for fluency (it is probably too detailed a description), but may be readded if a reference can be found. Thanks! Bibeyjj (talk) 21:40, 2 February 2022 (UTC)[reply]
