Is the thalamus part of the basal ganglia? What are cholinergic neurons? What are axons? What is the adrenal cortex? What does the dorsal root ganglia contain? What are multipolar neurons? Where are autonomic ganglia located? Is the basal ganglia the choroid plexus?
The basal ganglia (BG) are known to play a role in motor, cognitive and associative functions (see Sect. 1 of Part I of The Subthalamic Nucleus ). However, the role of the BG in motor control appears to be the dominant one, and will be the emphasis of this research. It is widely ...
The white matter of the cerebrum, which underlies the grey matter, and intervenes between cortical grey matter and the basal ganglia, contains three types of fibers.The association fibers connect the different regions in the same hemisphere. ▼投射纤维,例如放射冠(下图),连接皮层至脑的尾端和脊髓。
In patients with Huntington’ s disease, it’ s the part of the brain called the basal ganglia that’ s destroyed. While these victims have perfectly intact explicit memory systems, they can’ t learn new motor skills. An Alzheimer’ s patient can learn to draw in a mirror but can’ t...
Numerous attempts have been made to describe the functions of the basal ganglia (BG; Divac and Oberg, 1979). The number and variability of proposed concepts reflect different approaches to the study of the BG, the complexity of the organization of the forebrain, as well as the imagination of...

Natural movements are corrected in part by the generation of submovements, occurring early in a movement such that they amend an ongoing action. Submovements are associated with activity of the basal ganglia, implying a role for the structures in error correction. In parallel, the basal ganglia ...
The primate basal ganglia receives information from most of the cerebrum, including the frontal cortex, but projects (via the dorsal thalamus) primarily to the frontal lobe, perhaps in its entirety. As such, the frontal cortex and basal ganglia constitute an integrated, distributed neuronal architect...
