查询词典 neuron

Keywords: Neural network, Competitive learning, Vector quantization, Neuron underutilization, Algorithm

与传统竞争学习算法只有一个神经元获胜而得到学习不同，PSCL算法按照各神经元的获胜概率并通过对失真距离的调整使每个神经元均得到不同程度的学习，可以有效地克服神经元欠利用问题。

RESULTS: Four hours after operation, rats injected with bletilla particles developed temporary conscious disturbance, and sustained hemiparesis of contralateral limbs with spontaneous circling behavior. Ischemia or infarction was found obviously in the cortex of parietal, frontal lobes and basal nuclei of the right cerebral hemisphere, where the neurons characterized with vague outlines, pyknosis and necrosis of neuron nuclei were recognized as well. But hemiparesis and spontaneous circling behavior only lasted for 12 h after embolization with bletilla gum.

结果：白芨微粒组大鼠术后4 h内呈现意识障碍，持续性对侧肢体轻度偏瘫及环转，TTC染色显示右侧大脑半球额叶、顶叶皮层和基底核附近局灶性缺血或梗塞，光学显微镜下可见缺血区脑组织水肿或坏死，神经元轮廓模糊，核固缩或裂解等；白芨胶组仅在术后术后1 h内有轻度意识障碍，12 h内出现对侧肢体行动障碍，但未见明显病理改变。

Compared to state-of-the-art methods based on Kohonen's adaptive-subspace self-organizing map, our method avoids confusion of data in the manifold representation. Each neuron in the network approximately learns the mean vector and principal subspace of the data in its local region. The data representation is therefore more discernable.

与现有的基于Kohonen的自适应子空间自组织映射网络(Adaptive-subspace self-organizing map， ASSOM)方法相比较，本文方法有效地克服了流形表达中出现的数据混淆现象，网络中各神经元渐近学习各自区域内样本数据的平均向量和主元子空间，数据表达更加清晰可辨。

OECs were cultured in the olfactory bulb of newborn Wistar rat. OECs suspension was infused into the lateral cerebral ventriculus of EAE rats, and the saline with the same quantity was infused in pseudo-operation group. Afterwards, motor-function grade, histo-pathological change and expression of apoptosis of neuron were observed.

In the same neuron, veratridine (1.5～5.0 μmol/L) caused slow wave oscillations of interspike intervals, while aconitine (10～200 μmol/L) caused tonic firing.

结果发现，在同一神经元，藜芦碱(1.5～5.0 μmol/L)可以引起放电峰峰间期的慢波振荡，即峰峰间期由大逐渐减小，然后又逐渐增大，形成重复的振荡波形，每个振荡持续约数十秒至数分钟；而乌头碱(10～200 μmol/L)则引起强直性放电，即峰峰间期逐渐减小，然后维持在一个稳定的水平。

Wiesel found that the visual perception originates from the receptive field of visual neuron.
