神经细胞

Synapses are the junctions between nerve cells, and their action is central to learning and memory.

神经节是神经细胞之间的结合点，它们对学习和记忆起至关重要的作用。

They are also looking at the number of synaptic connections between nerve cells in the two groups, as this could also provide useful information.

他们还研究了神经细胞间突触连接的数量，这也会提供有用的信息。

In ER-containing spines, we frequently observed synaptically triggered calcium release events of very large amplitudes.

当神经细胞受到刺激时，含有内质网的棘会释放大量的钙，从而引发突触功能的变化。

Here, we describe the isolation, expansion, and in itro characterization of adult mouse tegmental NSCs and their differentiation into functional nere cells, including dopaminergic neurons.

在本文中，我们将展示成体大鼠被盖区NSCs的分离、扩增、体外鉴定及分化为功能性神经细胞的过程。

Results:① Neuroglobin-immunocreactive positive cells were detected in cortex, thalamencephalon, hippocampus, hypothalamus, cerebellum, brain stem and spinal cord;② Ngb-IR positive nerve cells were also detected in peripheral nervous system such as intramural ganglia, myelinated nerve fiber and retina;?Substantial Ngb protein expression was also found in metabolically active endocrine tissues such as the pituitary gland , adrenal gland and testis.?

结果：(1)在所观察的大脑皮质、海马、丘脑、下丘脑、脑干、小脑和脊髓神经细胞都出现Ngb蛋白免疫阳性反应，不同区域表达强度不同：(2)在外周神经系统的神经节、有髓神经纤维和视网膜也观察到Ngb免疫阳性反应；(3)垂体、肾上腺、睾丸也可见到Ngb-IR阳性细胞。

Apoptosis may be also involved in the pathogenesis of neuronal death induced by this thrombotic ischemic lesion.

血栓性脑缺血损伤中存在细胞凋亡现象及凋亡相关基因Bc1-2、Bax的表达，细胞凋亡也参与了血栓性脑缺血所致的神经细胞死亡过程。

Though can not accurate induce neural stem cells specific orientation differentiation yet,to accompany the unceasing deepen recognize of convection mechanisms in cells' signal convection and discovery of new cell facter,new chemo-signal, Homo sapiens would solve the question of orientation differentiation from totipotential stem cell,multipotential stem cell to neural stem cell, orientation nerver ancestor cell then special tipe neural cell, implementation functional reconstruction betwen neural cell,for ultimate solve the proble of neural regeneration developing the way.

尽管目前尚不能准确有效的诱导神经干细胞特异性定向分化为某种特定的神经元，但随着人们对细胞间信号传递机制认识的不断加深和新的细胞因子、化学信号的不断发现，人类将能够解决从全能干细胞、多能干细胞到神经干细胞、定向神经祖细胞直至特异类型神经细胞的定向分化，完成神经元之间的功能重建，为最终解决中枢神经再生这一难题而开辟道路。

It was found that SO2 derivatives increase the amplitude of IA in CA3 neurons, and inhibit the inactivation of IA. After SO2 derivatives application, normal sensory physiology of hippocampal neurons was affected. This variation caused by SO2 could underlie the toxical modulation of sensory input to the central nervous system.

说明SO2代谢衍生物可增大大鼠海马CA3区神经元IA电流，延长A-电流的失活时间，从而影响海马神经元的膜生理感应，这可能是SO2影响神经细胞功能的机理之一。

Cytomorphology changes occurred obviously in cultured neurons such as cell edema, cell atrophy, etc."Jiu Nao Ning"Injection could improve the activity, decrease the transudation rate of LDH and the apoptotic rate. It could also increase the contents of DNA, RNA and improve the pathologic changes in cultured neurons.

救脑宁注射液高、中、低剂量组，在各时间点表现出不同程度地提高细胞代谢率、降低LDH漏出率和凋亡率的作用，与模型组比较p＜0.05；同时也显示出改善细胞形态学异常变化、增加细胞内DNA、RNA含量，保护神经细胞功能与结构免遭损伤等作用，以中剂量效果最好，其与清开灵的药效作用相比，要么相似要么更佳。

A branching,treelike shape or arrangement ,as that of the dendrite of a nerve cell.

树枝状，树枝分枝分枝的、似树的形状或排列，如神经细胞的树状突分布

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
