The substantia nigra is a small motor nucleus, within the anterior part of the midbrain, between the cerebral peduncle and tegmentum of the midbrain. Despite its location in the midbrain, function-wise it is considered part of basal ganglia. The substantia nigra consists of two parts with ...

because she fears her body will slip down the drain, a man who is convinced he is a cat, a woman who compulsively snacks on cigarette ashes, and many other unusual cases. As uncommon as they are, each of these cases has something important to teach us about everyday brain function. ...
these nuclei were collectively identified as a conduit for information to pass from cortical association regions to motor cortex for the initiation and control of movement. Today, the function of the basal ganglia is thought to include not only the shaping of motor...
The role of cholinergic systems in basal ganglia function is also under-researched. The presence of cholinergicinterneuronsin the striatum has been known for many years, and there is clearly a functional interaction between these cells and the dopaminergic input to the striatum as well as with GABA...
Functional Aspects of the Basal Ganglia However, several major gaps remain in our understanding of basal ganglia anatomy and function, specifically with regard to their descending (brainstem) projections, and their interactions with other brain regions, such as thalamus or ... T Wichmann 被引量: ...
Damage to its basal ganglia part, Area X, in adult zebra finches has been noted to have no strong effects on song and its function is unclear. Here we report that neurotoxic damage to adult Area X induced changes in singing tempo and global syllable sequencing in all animals, and ...
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. Its input structure, the striatum, receives a dense dopaminergic input that is critical for reinforcement ...
Detailed Description Reinforcement Learning and the Basal Ganglia For nearly a century, a certain “mysteriousness” has been attributed to the function of the basal ganglia (BG) system – a deep brain circuit of multiple interconnected nuclei, with rich connections to large parts of the cortex (...
