A target-specific electrode and lead design for internal globus pallidus deep brain stimulation.

abstract：BACKGROUND:Deep brain stimulation (DBS) is widely used to treat advanced Parkinson's disease, other movement and psychiatric disorders. DBS implantation requires application of a stereotactic frame throughout a lengthy procedure, making it uncomfortable and tiring. We designed a stereotactic cube to stage the operation...
