1、Neural network correlated with LIFG and RIFG exists in normal subjects in resting-state,which might be the neural foundation in retaining the normal language function;2、The left fusiform gyrus,bilateral medial frontal gyrus and right anterior cingulum in aphasia patients after stroke showed low degree correlation,that might be one of the mechanisms of aphasia;3、The brain regions showed positive correlation with RIFG in aphasia patients only exist in right hemisphere in resting-state as well as which exist in bilateral hemisphere in normal subjects,suggested that RIFG is out of correlation with the left hemisphere in aphasia patients;4、The left thalamus showed positive correlation with RIFG only in normal subjects, inferred that the left thalamus might be an important mesomerism structure in the correlation of bilateral hemisphere;5、Left insula showed stronger positive correlation with RIFG in normal subjects than that in aphasia patients,suggested that dominant hemisphere insula is important in retaining in normal language function.

1、正常人在静息状态下即存在与LIFG和RIFG具有相关性的神经网络，该网络可能是维持正常语言功能的神经基础；2、脑梗死后运动性失语患者左侧梭状回、双侧额叶内侧回、右侧前扣带与LIFG的连接程度的减低可能是运动性失语的发生机制之一；3、与RIFG正相关的脑区在对照组为双侧半球分布，而在患者组仅出现在右侧半球，说明患者组RIFG与左侧半球的连接中断；4、RIFG与左侧丘脑的正相关性仅出现在正常对照组中，推测左侧丘脑可能是联系两侧半球功能区的重要中介结构；5、对照组与RIFG正相关性明显高于患者组的脑区位于左侧岛叶，说明优势半球岛叶对维持正常语言功能具有重要作用；第二部分脑梗死运动性失语患者语言恢复机制的静息态fMRI初步探讨目的：运用fMRI技术，采用种子点方法在静息状态下分析脑梗死运动性失语患者不同的恢复阶段语言功能连接方式。

In the brain of adult rat, the positive immunohistochemical product of lSL-l (ISL-l-positive) was mainly located in the neuronal nucleus and found in discrete regions except to brain cortex, such as the Purkinje cell layer and the granular cell layer of cerebellum, the granular cell layer and the pyramidal cell layer of hippocampus, the mitral cell layer, the internal and external plexiform layer, the granular cell layer and the granular cell layer of olfactory bulb and so on, and several nuclei of the hypothalamus, midbrain and pons, such as claustrum, anterior olfactory nucleus, accumbens nucleus, caudate-ptamen, pallidum, substantia nigra, striatum, islands of Callaje, mammillary nucleus, anterior pretactal nucleus, habenular nucleus, amygdaloid nucleus, cuneate nucleus, rubral nucleus, gigantocellular reticular nucleus and so on.

在正常成年大鼠脑中，同源框基因islet-1表达产物（ISL-1）免疫组织化学阳性物质广泛分布于除大脑皮层外的神经细胞的细胞核内，ISL-1阳性神经元密集分布于小脑Purkinje细胞层和颗粒细胞层、海马的颗粒细胞层和锥体细胞层、嗅球的内丛层、外丛层、颗粒细胞层及僧帽细胞层等，另外在丘脑、中脑和桥脑的一些重要神经元核团均有分布，如，屏状核、前嗅核、伏核、尾壳核、苍白球、黑质、纹状体、Calleja岛、乳头体核、前顶盖前核、缰核、杏仁核、楔束核、红核网状巨细胞核等。

Objective To study the correlation between hypermethylation of the CPG island of p16 gene and its inactivation in gliomas.

目的探讨脑胶质瘤中p16基因CPG岛甲基化与该基因失活的相关性。

Our within-subject analysis also showed activation of brain areas associated with negative emotions, including right insula and putamen (11, 38), during the high-stress relative to the low-stress task. The observed activation in the dorsomedial prefrontal cortex ACC and precuneus parietal cortex may ref lect mental arithmetical performance (39) and assessment of the mental state (40) during the serial-subtraction task, whereas the CBF reduction in pre- and postcentral gyri and temporal cortex may ref lect more frequent verbal movement and greater auditory stimulation during counting backward versus serial subtraction.

我们的在之内主题分析也显示了脑子区域的活化作用与消极情感相关，包括正确的脑岛并且putamen (11， 38)，在期间高注重相对低注重任务在连续减法任务期间，被观察的活化作用在dorsomedial前头叶外皮ACC和precuneus头顶骨外皮可以ref lect精神算术对精神状态(40)的表现(39)和评估，而CBF减少前和中央后回和世俗外皮可以ref lect更加频繁的口头运动和更加伟大的听觉刺激在计数期间落后对连续减法。

In addition, the loss of the gray-white differentiation in the cortical ribbon (particularly at the lateral margins of the insula) or the lentiform nucleus and sulcal effacement can often be detected within 6 hours in up to 82% of patients with large-vessel anterior circulation occlusions.

另外，82％的前循环大动脉闭塞的患者，于发病6小时内，CT即可发现岛带征（岛叶外侧缘皮层灰白质分界消失）、豆状核低信号征、半球脑沟消失征；这些早期CT征象的出现往往提示预后不良。

One-sample t test was used in profoundly congenital hearing loss infants and control group,the activated brain areas were:bilateral transverse temporal gyri, superior temporal gyrus,middle temporal gyrus,bilateral insular lobe,bilateral precentral gyrus,postcentral gyrus,bilateral cingulate gyrus,bilateral inferior parietal lobule,bilateral superior parietal lobule,bilateral superior frontal gyrus.

在对极重度感音神经性耳聋患儿和对照组进行组间比较发现，病人组数据减去对照组数据时可见激活的脑区主要有：双侧颞横回、双侧颞上回、双侧颞中回、双侧岛叶、双侧中央前、后回、双侧扣带回、双侧顶下小叶、双侧顶上小叶、双侧额上回等，提示极重度感音神经性耳聋患儿在接受刺激后动用了更多的脑区而且激活强度明显增加。

Right postcentral gyrus of frontal lobe(BA2,BA1),left inferior frontal gyrus(BA47),postcentral gyrus(BA43),right inferior parietal lobule(BA40),left superior temporal gyrus(BA22) and right insular(BA13) were evoked by twisting Shenmen point;Left inferior parietal lobule(BA40),right inferior frontal gyrus(BA45,BA46),left medial temporal gyrus and medial temporal gyrus(BA37) and left superior frontal gyrus(BA10) were evoked by twisting Yanglao point.

神门穴主要激活了右侧额叶的中央后回BA2、BA1，左侧额下回BA47和中央后回BA43，其次为右侧顶叶的顶下小叶BA40，左侧颞叶的颞上回BA22，右侧脑岛BA40；养老穴主要激活了左顶叶的顶下小叶BA40，右侧额叶的额下回BA45、BA46，其次为左侧颞中回、颞下回BA37，左额上回BA10。

All mammals have insulas that read their body condition, Dr. Craig said.

所有哺乳动物都有感知躯体状态的脑岛。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
