突触

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。

Objective To investigate the effects of pentylenetetrazol and nuclear factor kappa B decoy oligodeoxynucleotides on the expression of synaptophysin in neuron-like PC12 cells and explore the epileptogenesis.

目的 通过观测戊四氮(pentylenetetrazol，PTZ)及NP-кB圈套寡核苷酸结构对神经元样PC12细胞突触素(synaptophysin，P38)表达的影响，进一步探讨癫痫的发病机制。

The aim of this study is to investigate the EEG characteristics in frequency domain in frontal lobe, occipital lobe and hippocampus, i.e. cognition-related cortex of synaptic dysfunction model rat.

本文旨在探讨突触功能障碍大鼠模型在额叶、颞叶和海马这些与认知功能有关的脑区EEG频域特征。

① Synaptic density was found to decrease in frontal lobe, occipital lobe, CA3 area of hippocampus and putamen with age; the changes had significant correlation with age.

①脑老化过程中额叶、枕叶及脑海马CA3区与壳核突触密度随年龄增加而下降，尤其是脑额叶、枕叶及脑海马CA3区的这种变化与年龄的相关性更为显著。

We further assume that the total synaptic area that a neuron can support is metabolically constrained by its activity level and size.

我们进一步假设一个神经元可以支持的总突触面积，是由其活动水准和大小来代谢地制约的。

There was no modification of contractility in aging strips thatinduced by carbochol and noradrenalin, as well as the contractility inhibition by atropine.

超微结构中，存在逼尿肌不稳定的结构基础，即突触连接增加；2。老龄大鼠膀胱逼尿肌顺应性增强，弹性回缩力下降。

The three patches of receptive field existed a few overlapping areas and also had separate area. When the intensity of mechanical stimulation was controlled to evoke only one T cell excited, the simultaneous intracellular recordings with four microelectrodes (one in AP cell and the other three in three T cells respectively) could shown that under natural conditions AP cells can positionally discriminate the area of the mechanical stimulation on a single annulus with the postsynaptic potential.

将机械刺激强度控制在只激活一个T细胞时，利用四根胞内微电极同时记录（三根电极在三个T细胞内，第四根电极在AP细胞内），结果表明AP细胞在自然条件下对单个体环上的机械刺激区域确实具有突触后电位的部位分辨功能。

It is fuether demanded to confirm whether there is a synapse between SP-ergic and cholinergic neuron in the ENS.

在肠神经系统中，SP能神经是否与胆碱能神经元之间存在突触联系有待进一步证实。

慢性复合应激性学习记忆增强大鼠海马神经细胞增殖和突触后酪氨酸激酶表达的变化［J］。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
