basil ganglia

The basal ganglia are a group of interconnected structures deep within the brain that help coordinate movement, support motor control, and facilitate learning and habits. They work by processing information from the brain's cortex and communicating with other areas to regulate the initiation, tone, and smoothness of movements, as well as reward-related behaviors. When functioning properly, they ensure movements are purposeful and coordinated. Disorders of the basal ganglia can lead to movement problems such as tremors, rigidity, or difficulties with voluntary actions, as seen in conditions like Parkinson's disease or Huntington's disease.
