Actions are not mediated solely by cortical processes but rely on communication within basal ganglia-thalamocortical loops. Speech is one example, although how the basal ganglia participate in this ...

Most neuroscience studies investigating motor skills are carried out on rodents. In these experiments, rodents are typically tested on simple motor tasks that they can easily complete using motor ...

For decades, neuroscientists have thought about communication between the cerebral cortex and the basal ganglia in a fairly ...

This study aims to (i) compare volumes of individual basal ganglia nuclei (caudate nucleus, pallidum, and putamen) and the thalamus between very preterm (VP) and term-born infants at term-equivalent ...

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 ...

Researchers have found new evidence that the basal ganglia and the cerebellum, two important areas in the central nervous system, are linked together to form an integrated functional network.

Thousands of our daily activities, from making coffee to taking a walk to saying hello to a neighbor, are made possible through an ancient collection of brain structures tucked away near the center of ...

The substantia nigra is a motor nucleus located in the basal ganglia of the midbrain. This brain structure contributes to the body's cognitive and motor functions by sending signals to initiate or ...

Although dystonias are a common group of movement disorders, the mechanisms by which brain dysfunction results in dystonia are not understood. Rapid-onset Dystonia-Parkinsonism (RDP) is a hereditary ...

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 ...

A brain imaging study showed differences in the basal ganglia when chronic fatigue syndrome patients (CFS) vs. healthy controls played a card game. The findings suggest that chronic fatigue syndrome ...

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 ...
