神经突

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

Results In 84 cases of nerve root type,stenosis was found in 438 intervertebral foramen,of which C6～7 and C5～6 intervertebral foramen stenosis accounted for 79.6%.The causes of intervertebral foramen stenosis were uncinate process articulation hyperosteogeny,intervenebral disc protrusion,vertebral body hypertrophy,zygapophysis hyperosteogeny and dislocation etc.40 cases of vertbral artery type manifested that vertbral artery became slim and deviousness as a result of the compression of vertbral artery （20.7%） by osteophyte.22 cases of myeloid type manifested with cervical spinal canal stenosis,hyperosteogeny of posterior vertebral body edge,posterior longitudinal ligament calcification and cervical intervertebral disc protrusion etc.

结果 84例神经根型中，发现椎间孔狭窄438处，其中C5～6和C6～7椎间孔狭窄占79.6%，椎间孔狭窄的成因有钩突关节骨质增生、椎间盘突出、椎体肥大、小关节突骨质增生、错位等；40例椎动脉型表现为骨赘压迫椎动脉（52.5%），导致椎动脉变细、粗细不均和椎动脉迂曲。22例脊髓型表现为颈椎椎管狭窄、椎体后缘骨质增生、后纵韧带钙化、椎间隙狭窄和颈椎间盘突出等。

An enriched PCR fragments with less complexity were obtained and mainly expressed in the denervated hippoampus After cloning into the plasmid vector, 46 clones were initially screened and subjected to autosequencing By comparison with the EMBO gene databases, 21 gene fragments of different types were obtained with 11 similar to genes of known function and 10 similar to ones of unknown function It is inferable that the altered gene expressions of hippocampus following the entorhinally denervation may underlie the specfic reinnervation and the formation of synapses by transplanted entorhinal neurons with host neuropil within the denervated target areas.

初步挑选出的46个转化后的阳性克隆，经点杂交筛选和基因序列分析，与Gene Database同源性比较后，得到21种基因片段，其中功能已知的有11种，功能未知的有10种。结果表明海马在去内嗅皮层后某些基因表达的改变，这可能是移植胚胎内嗅皮层神经细胞轴突特异支配去神经靶区和重建突触联系有关。

That speed, in turn, depends a great deal on the myelination of the neuron's axons… The more myelin sheathes the axon, the faster the neuron can conduct its charge.

速度，在又取决于了大量关于髓鞘的神经元的神经轴突…更髓鞘sheathes轴突，更快的神经元可以进行收费。

Nerve cell The body of a neuron without its axon and dendrites.

Through immunocytochemistry study, we found that the α3 and/or α5 subunits of nicotinic acetylcholine receptor are predominantly expressed in the oxytocinergic neurons. Our finding is quite different from the conclusion of the British scholar Dr. Mason's work in 1980s. We also found in this study that, the α3 and/or α5 subunits of N-AChR can also be expressed on the axons of oxytocinergic neurons, and these immunoreactive axons could be seen projecting to the median eminence and further to the posterior end of neurohypophysis. In the hypothalamus of the 7-day postnatal pup rats, the expression patterns of α3 and/or α5 subunits of N-AChR are similar to that in adult rats.

我们用免疫组化的方法发现，α3和/或α5型烟碱型乙酰胆碱受体(Nicotinic acetylcholine receptor，N-AChR)亚单位在大鼠下丘脑OT能神经元中呈优势性的表达，这与上世纪八十年代英国学者Mason类似工作的结论不一致；而且我们还发现α3和/或α5型N-AChR亚单位还表达在OT能神经元的轴突，此阳性免疫反应的轴突一直延续到正中隆起和神经垂体的末端；在新生7天大鼠的下丘脑，α3和/或α5型N-AChR亚单位的分布类似成年鼠。

The expression and axonal transport of pituitary adenylate ecelase-activing polypeptide was reported, The number of neurons immunoreactive for PACAP increased markedly within the nodose ganglion during a 24-48h culture period, PACAP was found to axonally transported and accumpulated at the site of a crush injury.

另有一个研究，是调查在体外培养的鼠迷走神经中垂体腺苷酸环化酶激活多肽的表达和轴突输送，提出在24-48小时的培养期，PACAP免疫反应性神经元的数目在结节神经节内显著地增加，PACAP参与轴突输送中并堆积在受损部位，在这部位被释放。

With reference to the theory that only a part of signal from brain cells can reach pallium put forward by Raju Metherate,and the theory that axon signal strength is reduced with distance increment from main body of neural cells raised by Stephen R Williams,axon signal theory-based clustering algorithm of neural network is presented in this paper.

通过借鉴Raju Metherate提出的只有部分脑细胞发出的信号到达了大脑皮层的理论和Stephen R Williams提出的突触信号强度随着离神经细胞主体的距离的加大而减弱的理论，提出了基于轴突信号理论的神经网络聚类算法。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
