Posterior subthalamic area
Posterior subthalamic area deep brain stimulation.
The posterior subthalamic area (PSA) includes the zona incerta (ZI) and the prelemniscal radiation (RaprL), which itself consists of the cerebellothalamic fascicle (fct) (or dentato-rubro-thalamic tract [DRTT]) and pallidothalamic fibers, and was targeted for lesioning as early as 1960 by Wertheimer et al. 1).
