神经突

The storage capacity a0 and addressability of a nonlinear neural network suitable for optical implementation have been studied by means of computer simulation. A Monte Carlo algorithm to improve its synaptic interconnection matrix is proposed.

本文用计算机仿真研究了一种适于光学实现的非线性神经网络模型的存储客量α_c和寻址能力，提出了一个改进其触突互联矩阵的蒙特卡洛学习算法。

In RPE cell culture, Sox2 promoted the expression of retinal ganglion and amacrine markers, and suppressed the expression of genes associated with RPE properties.

在RPE细胞培养中，Sox2促进了视网膜神经节细胞和无长突细胞标记物的表达，并抑制RPE功能相关的基因的表达。

The researchers injected a substance into the retina to eliminate ganglion cells (a type of nerve cell found near the surface of the retina) and amacrine cells.

研究人员注入了实质内容纳入消除视网膜神经节细胞（一种神经细胞附近发现表面的视网膜）和无长突细胞。

Immunohistochemistry was utilized to investigate the light and electron micros- copic localization of neurotensin-like immunoreactive amacrine cells in the chicken retina.

本实验用光镜和电镜免疫组织化学方法研究神经紧张素(neurotensin，NT)样免疫反应无长突细胞在鸡视网膜的定位。

These all show pronounced stratification. There are three kinds of neurons related to the optic lobes: amacrine cells, columnar neurons and tangential neurons, only a few of which are stained.

视叶包含三种神经元：无长突神经元、柱状神经元和切向神经元，其中只有少数被标记，与前脑间的神经通路呈弱阳性反应。

AIM: To observe the changes of tyrosine hydroxylase protein levels and the density of dopaminergic amacrine cells before and after the administering brain derived neurotrophic factor protein into the vitreous cavities of streptozotocin reduced Wistar diabetic rats.

目的：观察玻璃体腔内注射脑源性神经营养因子（Brain derived neurotrophic factor，BDNF）前后STZ糖尿病大鼠视网膜中酪氨酸羟化酶（tyrosine hydroxylase，TH）的水平及多巴胺能无长突细胞数目的变化。

Its role in axon repellent and cell migration were extensively studied in different systems.

Slit2是一个200 kDa分泌型醣蛋白，过去的研究著重於对神经轴突的迁徙上所扮演的抑制性角色。

"Our observations, combined with those of others, suggest that widespread axonal dysfunction is associated with fatigue in MS," write Maria Carmela Tartaglia, BSc, MD, from Montreal Neurological Institute and Hospital in Quebec, Canada, and colleagues."It may be hypothesized that diffuse white matter disease translates into an increase in the central nervous system effort required by a patient with MS to perform the same activity as compared with a disease-free subject, with resultant fatigue."

来自加拿大魁北克医院及蒙特娄神经学学会的Maria Carmela Tartaglia博士和其同僚表示，他们的观察结合了其他人的之后建议，多发性硬化症患者的疲劳症状和广泛性轴突功能障碍和有密切关联，其可被假设为为当多发性硬化症患者在和其他正常人做同一活动时，其弥漫性白质疾病导致中枢神经做功增加，而产生较疲劳的结果。

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。
