Outcome Measures
Primary Outcomes (1)
Neuronal differentiation into dopaminergic neurons
Differentiation of at least 10% of dopaminergic neurons is targeted as the primary outcome measure
6 months
Study Arms (1)
Neural stem cells
Interventions
During neurosurgical procedures, tissue samples are obtained along trajectory of implanted electrodes or removal of stimulators previously implanted.
