Feasibility Study of Deep Brain Recordings for Learning and Memory

Background: \- Some people with movement disorders are in another NIH protocol. They will have electrodes placed in deep brain areas. They may do tasks before, during, and after surgery. Researchers want to learn more about how brain cells and networks work while people learn and remember. They want to use the data from the other NIH study to do this. Objective: \- To share data from before and during deep brain stimulation surgery. The data will be used in a study of how the brain learns and remembers. Eligibility: \- People at least 18 years old who are in protocol 11-N-0211 and have certain movement disorders. Design: * As part of protocol 11-N-0211, data on participants brainwave activity is collected. In this protocol, they will have that data stored and shared. * Researchers will access imaging data from deep brain stimulation surgery. * Researchers will access other medical records.
