An adaptive PID controller for thrust speed of a hydraulic thrust system in shield machine based on the single neuron structure was designed on the basis of the fact that the single neuron features the PID characteristics.

在分析单神经元PID特性的基础上，设计了基于单神经元的盾构推进液压系统速度自适应PID控制器。

These observation have prompted the close relationship between the hyperexcitability of the neurons and the mechanism involved in the common illnesses such as sciatica and low back pain.

这与临床上常见的坐骨神经痛、下腰痛等病征的产生有密切关系。了解DRG神经元的生理特性，将为进一步阐明病理条件下，神经元兴奋性异常增高的机理奠定基础。

Results After oral administration of ST pinocytosis vesicles began to increase in endothelial cells of blood vessel in 1 hour,apocrine of ependymal cells began to increase and myelin sheath degeneration appeared in 2 hours,extensive myelin sheath degeneration and mitochondrion degeneration and incisure and vacuoles in nucleus of neuron were found in 4 and 8 hours.

结果 ST灌胃后1 h血管内皮细胞吞饮囊泡开始增多，2 h组室管膜细胞的顶浆分泌增多，部分神经髓鞘变性；4 h和8 h组神经纤维广泛变性，神经元线粒体变性、核切迹和空泡出现；16 h组神经元胞浆内线粒体变性更加明显，并出现脂褐素。

The resting membrane potential and input resistance of DCN neurons were -60±6 mV (range -53 to-70 mV, n=19) and 484±298 MΩ(range 88-1635 MΩ, n=70), respectively.

DCN神经元的静息膜电位和输入阻抗分别为-60±6 mV（n=19）和484±298 MΩ（n=70）。大部分神经元的电流电压曲线呈现内向整流。

Alpha motor neurons send collateral axons to internuncial Renshaw cells that normally act to inhibit the motor neuron pool (feedback or recurrent inhibition).

运动神经元向闰绍氏细胞发出轴突，通常是为了抑制运动神经元池，运动传出通路能特别激活闰绍氏细胞。

The former, intracranially complements patients some factors, most frequently with TH gene to compensate scanty of intrastriatal DA and improve the symptoms of the patients, while have little resistance to the progressive degeneration of dopaminergic neurons; The latter provide variety of neurotrophic factors, most specific being the glial cell-line derived neurotrophic factor , to protect the residual DA neurons in the nigrostriatal system from further pathogenic injuries, while have little benefit to those DA neurons with irreversible damage, and them cannot offset the already-existing symptoms.

前者是给宿主脑内补充某些因子，主要是DA合成过程中的限速酶TH基因，以补充纹状体内DA含量的不足，减轻患者的症状，但对DA能神经元的进行性退变没有治疗效果；后者则是提供各种神经营养因子其中最具特异性的为GDNF，以保护黑质一纹状体系统内剩余的DA能经元免受病因的继续损害但对已发生不可逆性损害的DA能神经元并无拯救作用，无法消除已出现的症状。

The pathologic phenotype in all cases has thus far included ubiquitinated neuronal intranuclear inclusions and neuronal cytoplasmic inclusions.

其病理表现包括泛素化的神经元的核内包涵体和神经元的胞浆包涵体。

Among 461 neurons, 176 were stimulus relative and 285 stimulus irrelative.

在被观察的神经元中，176个为刺激相关神经元。

Astric vagal and cerebellar fastigial nuclear afferents have been implicated in the regulation of food intake by their communication with lateral hypothalamic area, which is generally referred to be the feeding center.

我们和其他作者先前的研究表明，胃迷走神经和小脑顶核的传入均可到达LHA。本研究旨在观察胃迷走和小脑顶核的传入是否在LHA神经元，尤其是那些血糖敏感神经元上发生会聚，从而参予摄食活动的调节。

A way of blocking the activity of specific pain-sensing neurons without affecting other sensory or motor neurons could be used to create a more targeted form of local anaesthesia, and that is the prospect held out by Binshtok et al. in this issue.

一种阻断特定痛觉神经元的这种活性而又不影响其他感觉或运动神经元的方法，也许可用来创建一种目标性更强的局部麻醉方法，而这正是Binshtok等人在本期Nature上提出的一个观点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

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。
