Here are three type of lesioning surgery:

1. Thalamotomy involves the lesion being created in the thalamus of the brain. It is the least common type of lesioning surgery, and is only used rarely in current practice.

2. Pallidotomy involves targeting the region of the brain known as the globus pallidus internus. It is the most common type of lesioning surgery and can lead to the relief of tremors, rigidity, bradykinesia, motor fluctuations, dyskinesia and uncoordination.

3. Subthalamotomy targets the region in the subthalamic nucleus in the brain. It is not a common technique in most developed nations, but is a viable option in regions of the world where deep brain stimulation is not available for use in the treatment of Parkinson’s disease.
