The basal ganglia is a collective group of structures in the brain. These include the striatum, (composed of the putamen and caudate nucleus), globus pallidus, substantia nigra, and the subthalamic nucleus. Along with other structures, the basal ganglia are part of a neural circuit that is integral to voluntary motor function. [1]
The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates. In humans and other primates , differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum .
Hemiballismus or hemiballism is a basal ganglia syndrome resulting from damage to the subthalamic nucleus in the basal ganglia. [1] It is a rare hyperkinetic movement disorder, [2] that is characterized by pronounced involuntary limb movements [1] [3] on one side of the body [4] and can cause significant disability. [5]

The finding of bilateral periventricular relatively asymmetrical lesions allied with deep white matter involvement, that may also be present in cortical gray-white matter junction, thalami, basal ganglia, cerebellum, and brainstem suggests an acute demyelination process. [22]
Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis. [ 2 ] The word is from Ancient Greek ἐγκέφαλος , enképhalos 'brain', [ 37 ] composed of ἐν , en , 'in' and κεφαλή , kephalé , 'head', and the medical suffix -itis 'inflammation'.
The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement. Substantia nigra is Latin for "black substance", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons.

The name Bagadilico is an acronym formed using the two initial letters from the words Basal Ganglia Disorders Linnaeus Consortium. The group's ultimate goal is to find new therapies for Parkinson's disease and Huntington's disease. These disorders have in common that they are caused by disturbances in the part of the brain called the basal ...
