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 ...

The subthalamic nucleus (STN) and external globus pallidus (GP) form a recurrent excitatory-inhibitory interaction within the basal ganglia. Through a computational model of these interactions we show ...

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 ...

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 ...

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.

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 ...

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 ...

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 ...

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 ...
