The basal ganglia are a set of subcortical structures that interact with the cerebral cortex to regulate motor, cognitive and affective function through reinforcement learning and action selection.

Researchers at Karolinska Institutet, Columbia University and the University of San Francisco, have uncovered a previously ...

Neurons deep in the brain not only help to initiate movement-they also actively suppress it, and with astonishing precision. This is the conclusion of a new study by researchers at the University of ...

Dystonia is a neurological disorder characterized by involuntary abnormal muscle constrictions. The mechanism has not been well understood. Now, a Japanese research team has found that the decreased ...

Basal ganglia calcification is a very rare condition that happens when calcium builds up in your brain, usually in the basal ganglia, the part of your brain that helps control movement. Other parts of ...

Corticobasal degeneration is a progressive neurological disorder. When you have this disorder, you lose nerve cells and multiple areas of your brain shrink. This includes the cerebral cortex and the ...

‌Chorea is a movement disorder that stems from something wrong with the basal ganglia nerve structure deep in your brain. It causes involuntary movements of the hands, feet, and face. These movements ...

Watershed Infarction: Axial CT scan. Note the large hypodensity in the left basal ganglia and internal capsule. Although watershed infarcts are most often thought of as areas between two major blood ...

Deep within each half of the brain lies the caudate nucleus. It’s responsible for processing visual information, movement, and memory. Dysfunction may cause conditions like dementia or Parkinson’s ...

Watershed Infarction: Flair axial MRI scans. Note the large bright signal in the right basal ganglia and internal capsule. Although watershed infarcts are most often thought of as areas between two ...
