Cortical-Basal Ganglia Speech Networks
Cortical-Basal Ganglia Speech Networks
In this research study the researchers want to learn more about brain activity related to
 speech perception and production.
Speech production is disrupted in a number of neurological diseases that involve the basal
 ganglia, including Parkinson's disease (PD) and dystonia. The investigators will use a novel
 experimental approach and combination of analytic techniques to elucidate the contribution of
 neural activity in cortical-basal ganglia circuits to the hierarchical control of speech
 production, in subjects undergoing deep brain stimulation surgery.
Inclusion Criteria:

 1. Subjects scheduled for DBS implantation, as determined by the clinical
 multidisciplinary movement disorders board with definitive diagnosis of Parkinson's
 disease, essential tremor or dystonia.

 2. Subjects able to provide informed consent and comply with task instructions.

 3. Subjects 18-85 years old

 Exclusion Criteria:

 1. Subjects with reported hearing loss.

 2. Non-English-speaking subjects
