神经元

Firstly, we introduce the basic theory and methods for realization of SOFM. Subsequently we improve the arithmetic and implement the feature extraction of raw data using K-L translation, select the eigenvector. Combining C-avarage and ISODATA arithmetic, classify the eigenvector, according to the methods of this dissertation, in lower layer, set nerve cell and unite or delete nerve cells in middle layer, to improve the anti-huise- and robust.

论文首先介绍了SOFM的基本原理和实现方法，接着在其基础上对具体算法进行改进，用K-L变换对原始数据进行特征提取，选取出特征变量，结合C-均值和ISODATA算法对特征变量进行预分类，按照本文中介绍的方法在底层预置神经元，在中间层对神经原进行合并和删除，加强了该网络的抗干扰性和稳定性。

Methods: We divide the rats into 5 groups in random, with Morris method, detect the change of some active oxygen radicals such as super-oxide demitasse, Nitric Oxide Synthase, malondialdehyde etc. Also, we detect the change of cholinesterase, Monoamine Oxidize; using HE,PAS staining, immuno-histochemical technique, detect hippocampus CA1 cerebral pathology slices optical density value of NOS, CHE and lipofuscin of neural cell; detecting apoptosis rate and the expression of P53 , which are neuronal apoptosis related genes.

大鼠随机分为5组，采用"Morris水迷宫"法观察脑缺血性模型大鼠学习记忆功能，检测超氧化物歧化酶、一氧化氮合酶、丙二醛等自由基代谢异常的改变，检测胆碱酯酶、单胺氧化酶等老化相关酶的变化、脑组织神经细胞免疫组织化学技术、检查海马CA1区脑组织的病理切片，检测NOS、CHE光密度值；流式细胞技术：检测细胞凋亡率，及促细胞凋亡基因、P_(53)蛋白表达；病理切片采用HE染色、PAS染色及免疫组化法检查，检测对大鼠海马神经元细胞一般病理变化及脑细胞内脂褐含量。

In summary, age-related changes of GABA metabolism and dendrite on rat visual cortex were observed in the present study.

大鼠初级视皮层神经元的GABA分布、代谢具有明显的年龄相关性的变化。

Soma and dendrite of NOS neurons were similar in each group.

各组大鼠一氧化氮合酶阳性神经元的胞体和树突均相似。

Sympathetic ganglion cells have large Volume, simple shape no dendron and synapses on the cell body.

交感神经节细胞体积大，细胞的形状简单，无树突，突触位于细胞体上，神经节结构简单，但同时又具有中间神经元，在体外易于长时间存活。

However, we observed distinct abnormalities within presynaptic terminals of spinal MNs at the neuromuscular junction, as well as profound denervation.

无论如何，我们观察到神经肌肉接头处的脊髓运动神经元突触前末梢的明显的异常，还有显著的去神经支配。

In the dentate gyrus, many of the newly formed cells differentiated toward a neuronal phenotype.

在齿状回中，许多新近形成的细胞分化成一类神经元表型。

A few PV-IR neurons were seen in CA3 and the dentate gyrus until 38 weeks.

直至38周，CA3和齿状回内才可见到少量PV-IR神经元。

In vitro, these cells release serotonin and dopamine in response to membrane depolarization.

在体外，这些神经元可以释放5-羟色胺和多巴胺。

The subthreshold oscillations were induced by depolarization in 48% of the recorded neurons.

在本实验中，去极化能诱发阈下振荡的细胞占所记录神经元的48%。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
