neural nucleus 神经核 A spatially aggregated collection of nerve cell bodies in the CNS, consisting of one or more subpopulations that share cell type, chemical phenotype, and connections, and including nearby cells that share the same cell type, chemical phenotype, and connections. (CUMBO) AEO:0000136 Anatomical structure consisting of a discrete aggregate of neuronal soma[GO][GO_REF:0000021]. FMA:83686 Proposed CUMBO def from MM: A subcortical part of the nervous system consisting of a relatively compact group of cells that is distinguishable histologically that share a commonality of cytoarchitecture, chemoarchitecturel and connectivity. (comments: I put in 'subcortical' because I don't think we consider either the cerebellar cortex or cerebral cortex to be nuclei. Some people distinguish between a nucleus and a laminar structure (see Wikipedia definition). However, there are structures identified as nuclei that are laminar, e.g., lateral geniculate nucleus, although they are not laminated in all species. Also, I put in 'relatively compact' and 'distiguishable by histology' because we have groups of cells, e.g., cholinergic cell groups, doparminergic cell groups that are related on the 3 criteria but which we don't tend to consider nuclei because they don't occupy an easily defined territory. But all is open to debate. UBERON:0000125 nervous system nucleus neuraxis nucleus neuronal nucleus nucleus nucleus of CNS nucleus of neuraxis uberon CNS核 中枢神经系统中神经细胞体的空间集合，由相同细胞类型、化学表型和连接的一个或多个亚群组成，并且包括具有相同细胞类型、化学表型和连接的邻近细胞。 （CUMBO） 推荐的Cumbo def来自MM：神经系统的皮层下部分，由相对致密的一组细胞组成，这组细胞在组织学上可区分，具有细胞结构、化学结构和连通性的共性。（评论：我加入了"皮层下"因为我不认为我们将小脑皮质或大脑皮层认成细胞核。有些人区分细胞核和层状结构（参见Wikipedia定义）。然而，存在鉴定为层状核(例如，外侧膝状体核)的结构，尽管它们并非在所有物种中都是层状的。同样，我把"相对紧凑的"和"组织学上的不可逆"放在里面，因为我们有细胞群，例如胆碱能细胞群、多巴胺细胞群，它们在3个标准上是相关的，但我们不倾向于考虑核，因为其并不占领一个容易界定的区域；但所有的问题都有待讨论。 核 由神经元胞体离散集合体组成的解剖结构[GO][GO_REF:0000021]。 神经元核 神经系统核 神经轴核(neuraxis nucleus) 神经轴核(nucleus of neuraxis) central nervous system cell part cluster 中枢神经系统细胞部分群体
