DWI technique was much better than conventional T1WI, T2WI and FLAIR technique in definding specific cortical and basal ganglionic abnormalities.

DWI对于早期发现特异的皮层和基底节高信号优于传统核磁的T1WI、T2WI及FLAIR技术。

Methods MRI-based area measurements through several special coronal levels(anterior commisure, mamillary body and lateral genicular nucleus)of the hippocampus and entorhinal cortex were measured; the using imaging analyzer, we counted neuronal density of the hippocampus and entorhinal cortex on the same coronal levels.

应用MRI与组织学测量相对照的实验方法， MRI测量20例无明显神经系统疾病的人脑，在通过几个特定冠状层面上（前联合、乳头体及外侧膝状体），测量海马、内嗅区皮层厚度及面积；组织学方面应用图像分析仪进行神经元计数。

This view seems to require revision in views of more recent experimental finding that both relay cells in the lateral geniculate nucleus and the ganglion cells in the retina do show some orientation and direction sensitivities.

近年来大量的实验结果表明，视皮层下的外膝体神经元和视网膜神经节细胞都具一定程度的方位和方向敏感性，这些性质是遗传决定的，不受后天环境的影响。

Methods Differential display reverse transcription polymerase chain reaction was carried out to screen the differentially expressed gene fragments from the lateral geniculate body and the visual cortex.

利用差异显示反转录PCR技术分析大鼠外侧膝状体与视皮层基因差异表达情况，并筛选差异表达基因片段。

When skin is young, the natural repair functions in the germinative layer's mother cells perfectly counterbalance their deterioration, allowing them to reproduce as new, intact, identical daughter cells.

年轻时，肌肤真皮层内的母细胞拥有自然的修护性能，完美平衡皮肤细胞的退化，复制出完美健康的子细胞。

When skin is young, the natural repair functions in the germinative layer's mother cells perfectly counterbalance their deterioration, allowing them to reproduce as new, intact, identical daughter cells.

年轻时，肌肤真皮层内的母细胞拥有天然的修护机能，完美平衡皮肤细胞的退化，复制出完美健康的子细胞。

Recent advances in corticogenesis suggest that neurons migrate from the germinative zones through the white matter to the cortex when the white matter is most vulnerable and perhaps is being injured.

认知领域的新进展认为：当白质易受损伤或正在受损伤时，神经元从出芽区域通过白质向皮层迁移。

Rats of pancephalic ischemia and reperfusion were establ- ished with gyral vessel closing method by pulsinelli. SOD and MDA in cerebral tissue, transmitter content of catecholamine in hippocampal gyrus. striatum and neocortex, and patho- morphism of cerebral tissue of experimental animals were stu- died by piercing Baihui to Qubin of rats with filiform needle.

本课题采用Pulsinelli四血管关闭方法建立大鼠全脑缺血再灌注模型，对比观察了毫针透刺大鼠百会至曲鬓穴区对实验动物脑组织中SOD、MDA，海马、纹状体、新皮层中的儿茶酚胺递质含量及脑病理组织形态等方面进行研究。

Note that both pre- and post- central gyri, where the primary sensori-motor cortices are located, are relatively hyperperfused.

注意中央前回及中央后回区域，也就是主要的感觉运动皮层定位区在图中呈相对高灌注影。

In 15 cases（32.61%）,infarcts also appeared as wedge-shaped areas on CT or MRI,but located at marginal zones between the middle cerebral arteries and posterior cerebral arteries,the patient mailnly showed mild hemiparesis,hemianopia and apathy.

皮层后型15例，占32.61%，病灶在大脑中动脉和大脑后动脉供血的交界区，呈楔型，临床表现为轻偏瘫、偏盲、情感淡漠。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
