What is the basal ganglia?

The group of brain structures that help control body motions is called the basal ganglia.

As the brain plans and coordinates movements, information-in the form of electrical brain activity-flows between the structures within the basal ganglia.

Each structure within the basal ganglia plays a role in refining and modifying the information to help control muscle movements. When any part of the basal ganglia is impaired, information flow is altered. As a result, widespread movement control problems can occur, as is the case in Parkinson's disease.
