大脑半球

Anencephaly, the single most common open neural tube defect, is characterized by the absence of the cerebral hemispheres and the lack of bony calarium aboe the orbits Fig.

无脑畸形，最常见的单一的开放性神经管缺损，其特点是无大脑半球且没有眼眶以上的骨性颅盖（图10-37A-B和图10-37C）。胎儿有正常的中脑和后颅窝，但大脑半球未正常发育。

These speculations have been going on for over a generation. As an example, we may cite Campion and Elliot-Smith (1934) who proposed that thought consisted of corticothalamic circulation of impulses. Penfield has suggested the existence of a centrencephalic integrating system, which he has definedas that central system within the brain stem which is responsible for integration of varied specific functions from different parts of the hemispheres.

这些特性已经有好几十年了，让我们引用Campion and Elliot-Smith (1934)提出的论点为例，他们认为思考是由皮质丘脑的刺激循环所造成，潘菲尔提出中央头部统合系统的存在，他把这个系统定义成脑干的中央系统，负责不同大脑半球中各种特殊功能的整合，潘菲尔的说法使得这个系统的定义更为松散，以潘菲尔的定义来说，这个系统包含所有皮质下的灰色神经组织和其间的连接通道，并负责大脑半球内部的整合。

STG terminations were strongly left lateralized and overlapped with phonological activations in the left but not the right hemisphere, suggesting that only the left hemisphere phonological cortex is directly connected with the frontal lobe via the arcuate fasciculus.

颞上回终结点明显的位于左侧，在左侧大脑半球而不是右侧与音韵激活皮质重叠，这暗示只有在左侧大脑半球音韵皮层通过弓状纤维与额叶联系。

Laterality theory refers to insufficiently established dominance of one cerebral hemisphere over another.

单侧优势理论认为这都是由于一侧大脑半球对另一侧大脑半球建立起了不恰当的优势或统治地位。

Laterality theory refers to insuffi ciently established dominance of one cerebral hemisphere over another.

单侧优势理论认为这都是由於一侧大脑半球对另一侧大脑半球建立起了不恰当的优势或统治地位。

For most subjects with right-handedness, language cognition is dominated by the left hemisphere, which is also concerned by right hemisphere to various degrees and thus two hemispheres work by ways of both dissociation and coordination.

1。对于大多数右利手者，左侧半球主导语言认知功能，右大脑半球不同程度参与该过程，两侧半球分工协作。2。

The analyses confirm 7 cases with agyria, 5 with pachygyria of bilateral cerebral hemisphere and 3 with limited pachygyria of unilateral hemisphere.

结果显示：CT、MRI显示无脑回畸形 7例，双侧全大脑半球的巨脑回畸形 5例，单侧大脑半球的局限性巨脑回畸形 3例。

RESULTS: Compared with patients in the non-AD group, those in the AD group showed decreased cerebral glucose metabolism mainly in the temporal and frontal lobes and the limbic system in the right cerebral hemisphere and the inferior frontal gyrus and precentral gyrus in the left cerebral hemisphere, and increased cerebral glucose metabolism mainly in the temporal and occipital lobes in the right cerebral hemisphere and the parietal and occipital lobes and limbic system in the left cerebral hemisphere.

结果： 抑郁焦虑组与非抑郁焦虑组比较，脑葡萄糖代谢下降的脑区集中于右侧大脑半球，主要位于颞叶、额叶及边缘系统，左侧大脑半球较少，主要位于额下回和中央前回；脑葡萄糖代谢升高的脑区集中于右侧大脑半球的颞叶、枕叶和左侧大脑半球的顶叶，枕叶及边缘系统。

We found late magnetic reaction waves in two hemisphere of these volunteers by hearing animal's names and plant's names and the left hemisphere waves were much differentiate than that of right hemisphere. The results showed that Sensory's area is located at middle temporal gyrus, superior temporal gyrus and supramarginal gyrus.Conclusions: Sensory's area of Chinese people coincidence with the classic language center, that is, Sensory's area of Chinese people is located at middle temporal gyrus,superior temporal gyrus and supramarginal gyrus.

结果：所有受试者听动脉名称、植物名称均在双侧大脑半球诱发出明显的晚发磁反应波，其中左侧大脑半球磁反应波分化较右侧大脑半球好，听觉性语言中枢定位于左侧颞中回、颞上回、缘上回，结论：母语为汉语的正常人听觉性语言中枢与经典的语言中枢基本相符，即听觉性语言中枢定位于左侧颞中回、颞上回、缘上回。

But it also serves as a useful methodological development, which is a nice illustration as to how looking at people who are incredibly unusual, such as this man who had his brain bisected so his left hemisphere and his right hemisphere don't communicate with one another--how looking at such people, such extreme cases, can provide us with some understanding of how we normally do things.

但它也能作为一个有用的方法的发展，这是一个很好的演示如何看着那些不可思议的不寻常的，这样的人，所以他的大脑左半球bisected和他的右大脑半球不互相沟通——如何看待这种人，极端的情况下，可以给我们提供了一些了解我们通常做些事。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
