Basal ganglia: Gross anatomy and function - Kenhub
2023年10月30日 · The basal ganglia, or basal nuclei, are a group of subcortical structures found deep within the white matter of the brain. They form a part of the extrapyramidal motor system and work in tandem with the pyramidal and limbic systems .
Basal ganglia - Wikipedia
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.

2020年6月30日 · In simple terms, the basal ganglia provide a feedback mechanism to the cerebral cortex, modulating and refining cortical activation. Its main function is related to motor refinement, acting as a tonically active break, preventing unwanted movements to start. Much of this involves reducing the excitatory input to the cerebral cortex. This ...

所谓基底核( basal ganglia ) ，是指位于大脑半球下部的一些皮质下核团，这些核团与内囊相互贴邻，关系密切。 传统意义的基底核包括纹状体(corpus striatum ) 、屏状核(claustrum ) 和杏仁复合体(armygdaloid complex) 等结构。 现在，有些学者认为基底核主要由纹状体和与其联系密切的一些间脑和中脑的核团（主要是底丘脑核、黑质和脑桥核），集合形成对随意运动和行为动机进行调控的功能复合体。 至于 屏状核 的功能目前尚不清楚，由于杏仁体与边缘系统的关系更加密切， …

2022年9月26日 · The basal nuclei (or ganglia) are collections of subcortical nuclei (or gray matter) in each hemisphere that help regulate voluntary movements that are selected, planned, and executed elsewhere in the brain. Each basal nucleus basically consists of four masses: the caudate nucleus, the putamen, the globus pallidus, and the substantia nigra.
