SNr neurons in the midbrain send precise signals to control movement. Their activity determines which movements actions are initiated or inhibited. Neurons deep in the brain not only help to initiate ...

Using a novel system, researchers found that a part of the basal ganglia called the striatum is not involved in action selection as previously thought. Instead, the striatum and the motor cortex work ...

The basal ganglia are a group of interconnected structures, located in the midbrain below the cerebral cortex, that play a crucial role in motor control, reward processing, and cognition. This region ...

Located in the midbrain below the cerebral cortex, the basal ganglia are involved in reward, emotion, and motor control. This region is also the site of some of our most infamous movement disorders: ...

Among the many wonders of the brain is its ability to master learned movements—a dance step, piano sonata, or tying our shoes—acquired through trial-and-error ...

Athetosis and chorea are two types of involuntary movements that can occur in children and adults with neurological conditions, such as cerebral palsy. The movements have different features, and the ...

Neurons deep in the brain not only help to initiate movement -- they also actively suppress it, and with astonishing precision. The findings are especially relevant for better understanding ...
