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.

Basal Ganglia (Putamen) Intracerebral Hemorrhage: Axial CT scans. Note the large intracerebral hemorrhage originating in the area of the basal ganglia on the left. The basal ganglia is a common ...

Smooth movements require coordinated control of muscles. Even a simple reaching movement involves coordinated movements of his/her shoulder, arm, wrist and fingers, which are controlled by temporally ...

Basal ganglia calcification is when calcium deposits form in your brain. It can potentially cause a variety of neurological symptoms and can affect mood, perceptions, and behavior. The basal ganglia ...

Dystonia is a neurological disorder characterized by involuntary abnormal muscle constrictions. More than 300,000 people in North America are affected, but the mechanism of abnormal muscle ...

The arthropod central complex and vertebrate basal ganglia derive from embryonic basal forebrain lineages that are specified by an evolutionarily conserved genetic program leading to interconnected ...

Certain diseases, like Parkinson's and Huntingdon's disease, are associated with damage to the pathways between the brain's basal ganglia regions. The basal ganglia sits at the base of the brain and ...

Researchers have applied a chemogenetic tool in macaque monkeys and suppressed the subthalamic nucleus, a part of the basal ganglia circuitry. The chemogenetic suppression induced unstable movements.

This study aims to elucidate the neural mechanisms that underlie voluntary motor control driven by networks linking the motor-related areas in the cerebral cortex, cerebellum, and basal ganglia. To ...
