神经分布

Algorithm application of neural networks.Ⅲ Implementation of neuro-computers. The main contribution of the dissertation can be summarized as follows: 1 Hopf bifurcation of three kind of neural networks are discussed in detail, including type of discrete time delay, type of time delay with weak kernel and strong kernel as well as the proof of existence of bifurcation. Other problems such as asymptotic stability of bifurcation periodic solution, algorithm of determining the bifurcation direction, asymptotic stability and style of periodic solution are also studied. The average time delay is chosen as the bifurcation parameter, phenomena pertinent to system states of the continuous time delay network with strong kernel evolving from stable to oscillating, then back to stable again are observed.

论文的主要创新之处可以归纳如下： 1）针对目前国内外对神经网络的分岔研究较少的情况，论文中详细讨论了带离散时延神经网络、带弱核的连续时延神经网络、带连续分布时延且具有强核的神经网络的Hopf分岔现象，从理论上证明了Hopf分岔的存在性，并研究了分岔周期解的渐近稳定性，得到了确定周期解的渐近稳定性、分岔方向、周期解的渐近形式的算法；用平均时延作为分岔参数，发现带强核的连续时延神经网络中存在着系统的状态由稳定变化到振荡现象，当继续增加平均时延参数时，又从振荡变为稳定这一特殊的动力学现象。

Ota lesions scattered in the trigeminal nerve, two regional, Ito nevus distribution in the post and arm lateral supraclavicular nerve innervation area, according to the characteristics of nerve cells may be derived from melanocytes prompted local nerve tissue.

Throught adaptive algorithm of network, the system constantly revise right values distribute so as to meet goal. Distribute the heuristic knowledge and the experience knowledge to network interconnection and right value.?The reasoning machine carries on reasoning according to the knowledge that involve in knowledge base and fact that users offer.?Through front computation of nerve network, the output port obtains the output vector.?The explanation module of ES is explained to user.At last, this paper has realized grab hydraulic system based on ANNES intelligent diagnosis, it has proven this fault diagnosis method feasibility.

ANNES的工作过程是：①首先建立知识库；②学习系统获取知识时，它只要求专家提供范例及相应的解，通过神经网络学习算法对样本进行学习，经过网络内部自适应算法不断修改权值分布以达到要求，把专家求解实际问题的启发式知识和经验分布到网络的互连及权值分布上；③推理机根据知识库中的知识和用户提供的事实进行推理；④通过神经网络的前向计算，在输出端获得输出矢量：⑤经专家系

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.

结果显示，分类地位相近的三种甲虫脑结构大小相差悬殊：小青花金龟脑结构相对发达，蕈形体结构显著，具有发达的冠和叶，嗅叶发达；马铃薯瓢虫和榆紫叶甲的冠极度退化，嗅叶相对不发达；但榆紫叶甲具有十分发达的网膜后纤维和围咽神经。5-HT阳性纤维在三种甲虫的所有神经纤维网中几乎都有分布，且反应模式相似，但各神经纤维网特别是神经节层染色强度差异显著。5-HT阳性胞体有成群分布现象，且在三种甲虫脑中的空间分布位置基本一致。

Methylene blue-basic magenta staining and electron microscopy Regenerating nerve were arranged in bundles in group A and B, there were minifascicle formation and a large amount of proliferated collagen in between the minifascicled, no cicatrices form, regenerating vasa spread randomly, electron microscopy show a large number of myelinated and unmyelinated fiber arranged in buddies.

亚甲基蓝-碱性品红染色及电镜观察两组均见再生神经纤维呈束状分布，有多个神经束，每一个神经束内见大量密集、粗大的有髓神经纤维，神经束之间充满增生的胶原，未见瘫痕形成，再生血管散在分布。

The results showed an increased mean jitter value, fiber density and abnormal percentage both in EDC and AT muscles in group 1 and II diabetic patients comparing to the normal controls. These findings suggest an impaired or immatured neuromuscular junctions and an evidence of reinnervation through axonal sprouting in the diabetic patients either with or without nerve conduction abnormalities. In conclusion, the changes of axonal degeneration and reinnervation are the main pathophysiological mechanism of diabetic neuropathy, and the SFEMG is more sensitive than routine nerve conduction study in the diagnosis of diabetic neuropathyKeyword Axonal degeneration , diabetes mellitus , neuropathy , single fiber electromyography

结果显示两组糖尿病病患的连续间值差异，肌纤维密度及不正常比率比对照组显著增加(t试验，依序p.01)，在第一组糖尿病患中，伸指总肌的连续波间值差异比第二组高(p.05)，而连续波间值差异与纤维密度之间也成线性相关的增加(伸指总肌，r=0.471，p.01；胫前肌，r=0.386，p.02)，在伸指总肌测得的连续波间值差异上，第一组糖尿病患有75%不正常，第二组有33.3%不正常，而在胫前肌的连续波间值差异上，第一组糖尿病患有83.3%的不正常，第二组有75%不正常，在肌纤维密度的测定中，第一组糖尿病患的伸指总肌有27.8%不正常，胫前肌有58.3%不正常，第二组病患的伸指总肌有25%不正常，胫前肌有41.7%不正常，此结果表示糖尿病神经变造成的神经肌像交接处不稳定及有神经轴再生的重分布现象，因此也证实糖尿病神经病变的主要病理机转为神经的退化所致，而在诊断上单纤维肌电图检查的敏感度也比运动神经传导速度检查为高。

But our study suggested that the innervation of knee joint had two layer groups : the superficial layer group and the profunda layer group.
