Abstract

Pallidal discharges of patients with Parkinson's disease have been characterized as slow irregular or bursting discharges for the external pallidal segment (GPe) and fast discharges for the internal pallidal segment (GPi). Tremor-synchronous cells have also been described. Using microrecording techniques on 70 patients who underwent pallidotomy, we have recorded other types of pallidal discharges. In GPe, we recorded cells which fired fast, cells which were silent, and cells which fired tonically. In GPi, we recorded cells which burst following short segments of fast tonic discharges. We will demonstrate these cells and discuss their clinical significance.
