I should be glad to follow Jung in contrasting hysteria and obsessional neurosis as 'transference neuroses' with the paraphrenic affections as 'introversion neuroses', if it were not that such a usage would deprive the concept of 'introversion' of its sole legitimate meaning.

我很高兴依照荣格所说的，将癔症和强迫神经症称为&转移性神经症&，对比于将妄想呆痴病症称为&内向性神经症&，如果它不是说这样一种用法将剥夺它的唯一合法含义的内向性概念。

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.

In fact, case based-reasoning and BP neural network could be combined together to achieve the data fusion on the characteristic level. There is ability of analogizing and concluding in CBR. By using CBR, we are able to accumulate a set of cases.

为了使神经网络和CBR充分发挥各自的优点，互相补充对方的不足，将基于范例推理与并行BP神经网络结合起来共同完成特征级融合处理，提出了基于范例推理与神经网络的结合学习机制。

In this method, wavelet is used to extract fault characteristics and neural network is used to diagnose the faults; the inputs and outputs of the neural network are all memberships concretely, the inputs are the memberships of the crest factor, pulse factor, margin factor, bias factor, kurtosis factor and maximum spectrum on each characteristic domain, and the outputs are memberships of each fault.

即利用小波变换获取特征域，取特征域上的峰值因子、脉冲因子、裕度因子、偏态因子、峭度因子及频谱最大值作为神经网络的输入，并对神经网络的输入、输出进行模糊化处理，以神经网络进行诊断。

According to the afferent code, taste quality, rather than being coded by a single fiber or set of specific fibers depends on the pattern developed across a population of fibers, a cross-fiber patterning.

依照这种输入编码，味觉形式不是由单一神经或一套精确的神经所编码的，而是依赖于一种多神经交叉而发展的，这就是交叉神经系统。

The overall aim of the neural stem cell lab is to understand, at a molecular and cellular level, how endogenous mammalian neural stem cells are generated during development, and how their actions are regulated in the adult CNS, both under normal conditions and following disease or degeneration.
