A large number of computational models of information processing in the basal ganglia have been developed in recent years. Prominent in these are actor-critic models ...

The basal ganglia constitute a group of subcortical structures, highly interconnected among themselves, as well as with the cerebral cortex, thalamus and other brain areas. These nuclei play a central ...

Brain areas affected by drug use include the basal ganglia, the extended amygdala ... 1, 3 The brain disease model of addiction has contributed greatly to the current view of substance use disorders.

causes loss of motor functions largely due to atrophy in the basal ganglia (BG). Soma and Neurite Density Imaging (SANDI) 1 is a novel biophysical model yielding estimates of soma and neurite density ...

Methods: The authors examined the relation between employment as a welder and all basal ganglia and movement disorders (ICD-10, G20–26) in Sweden using nationwide and population based registers. All ...

Abstract: Dopamine (DA) depletion in the basal ganglia (BG) of Parkinson's patients gives rise to both frontal-like and implicit learning impairments. Dopaminergic medication alleviates some cognitive ...

RESULTS Normal visual behaviour was observed in most infants with large bilateral occipital lesions, but all the infants with associated basal ganglia involvement had abnormal visual function. Visual ...

Widespread abnormalities were seen on neuroimaging. A diagnosis of septic encephalopathy was established on postmortem. We describe the magnetic resonance imaging findings of bilateral basal ganglia, ...

secondary to the loss of midbrain dopamine neurons projecting to the basal ganglia. In addition to the cardinal motor symptoms, PD is accompanied by a wide range of comorbidities, which include ...
