Deep Brain Stimulation (DBS)
High-frequency neuromodulation for subcortical networks.
Mechanism of Action
DBS typically operates at 130Hz, creating a functional lesion or network regularization effect in targets like the STN (Subthalamic Nucleus) or GPi (Globus Pallidus internus). The transition to directional leads allows current steering to avoid side effects from stimulating adjacent tracts (e.g., corticobulbar).
