basal ganglia circuit

The basal ganglia are a group of brain structures that help control movement, motivation, and learning. They work like a command center, receiving information from the brain's cortex, processing it, and then sending signals to start, stop, or adjust movements. This system ensures movements are smooth, coordinated, and purposeful. It also plays a role in habits and decision-making. When the basal ganglia malfunction, it can lead to movement disorders like Parkinson’s or Huntington’s disease, affecting how a person moves or controls their actions.
