The carotid bifurcation on 8 sides had perforating arteries, and I l sides showed medial lenticulostriate artery of the middle cerebral arteries, with short course and overlapped with another perforating arteries upon entry into the anterior perforated substance.

豆纹动脉绝大部分从大脑中动脉M1段的分叉前段发出，但是大脑中动脉M1段的分叉越早，分叉后发出的穿通动脉越多。22侧半球存在大脑前动脉A1段的穿通动脉，进入前穿质时分支较多。

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。

The left side of the brain is rational, active, and realistic, the right side is emotional, metaphoric, impulsive, and intuitive.

大脑的左半球是理想的，活跃的和现实的，而右半球是感性的，隐晦的，冲动的和直觉的。

Age is an important factor affecting the level of NAA in frontal white matter.

年龄是影响额叶白质区域NAA含量的重要因素，随着年龄的增大，NAA含量会逐渐下降，性别和半球偏侧化对额叶代谢物浓度没有影响。

His review of experimental and clinical studies demonstrated that interactions with brain structures were important for the processing of nociceptive information.

完整成熟的大脑皮质有感受疼痛的基本特点，但是该理论因在有明显皮层损伤或半球切除术的患者存在持续感觉而受到挑战[1]。

"The dissociation between writing (a more common trigger for reflex epilepsy) and drawing emphasizes the presence of anatomically distinctive cognitive modules in the dominant and nondominant hemispheres."

通常能触发癫痫的书写活动和绘画引发的癫痫之间的无关联性揭示了：在占优势和非占优势的两个脑半球中，解剖结构上的思维模式明显不同。

Objective to assess the clinical effects of half-peribulbar injection of triamcinolone acetonide for thyroid related ophthalmopathy.

目的 评价曲安奈德半球后注射治疗甲状腺相关眼病的临床效果。

Cranial MRI showed round foci of signal change of different sizes in the subcortical white matter of the cerebral hemisphere, in the left paramedian portion of the pons and near the fourth ventricle.

脑部MRI见大脑半球皮质下白质的不同部位、左侧脑桥旁正中结构靠近第四脑室处散在许多圆形异常信号病灶。

First, the results revealed that the left middle temporal gyrus (BA 21) showed increased neural activity for phonologically primed irregular pairs consistent with increased semantic involvement in making lexical decisions when the mapping between orthography and phonology is made difficult.

三个主要的实验的结果如下：第一，当英文字对包含不规则字时，由於字形与字音的转换困难导致字义的涉入，在左脑半球的颞叶中区(BA 21)产生大脑神经活动增加的现象。

Regional cortical blood flow of cortex irradiated fell dramatically in the model of focal brain ischemia induced photochemically, to the level about 18% by control during ischemia 6h. But there were no changes in the unirradiated side.

光化学诱导局灶性鼠脑皮质缺血模型的光照区皮质灌流量显著下降，缺血6h时仅为缺血前的18%；而非光照侧半球的皮质灌流量无明显下降。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
