楔前叶

The function of precuneus may reflect the semantic matching process.

5楔前叶可能具有语义匹配加工的功能。

However, relative to the personal risk identification task, the environmental risk identification task resulted in greater transient activity in the posterior cingulate cortex and precuneus.

但是，相对于个人风险任务，环境风险任务导致较强的在后扣带回和楔前叶的短暂神经活动。

Posterior components of the default network, including the precuneus and posterior cingulate, are particularly vulnerable to early deposition of amyloid beta-protein, one of the hallmark pathologies of AD.

默认网络的后组成分，包括楔前叶和后扣带回，特别容易受AD病理学标志之一-淀粉样β蛋白早期沉积的损伤。

Campared among the three match conditions,there are more activation levels of non-matches than identical matches in precuneus,and there are more activation areas for non-matcher than that of the categorical matches in frontal,occipital and medial temporal lobes.

从三种匹配条件之间的差异来看，不匹配和名字匹配相比，在楔前叶的激活显著；而不匹配与类别匹配相比，在额区、枕区和内侧颞区都有激活。

In the results of the fMRI experiment,the activation level of picture-word identical matches condition is less than that of the categorical matches and non-matches conditions in precuneus,frontal and occipital areas,which shows repetition inhibition phenomenon.

4fMRI实验结果中，图-词的名字匹配在楔前叶、额区和枕区的激活比不匹配和类别匹配少，表现出重复抑制。

Previous studies have identified that understanding other's mind engages a neural circuit consisting of the medial prefrontal cortex, temporoparietal junction, superior temporal sulcus, temporal pole, and precuneus/posterior cingulated cortex. However, due to the limitation of experimental paradigms and neuroimaging data analysis approach, the exact neurocognitive mechanisms that underlie the understanding of others' belief remain unclear.

尽管前人的研究已发现内侧前额叶、颞顶联合皮层、后扣带回/楔前叶以及颞上沟等脑区参与他人信念理解，但是，由于实验范式本身和脑成像数据分析方法的局限性，过去的研究工作没有提出准确的认知神经机制来解释相关脑区组成的神经网络如何协同工作、完成视角转换以保证正确理解他人的信念。

Comparison results revealed that there was significantly reduced functional connectivity in the left posterior cingulate cortex, vbilateral anterior cingulate cortex, bilateral medial prefrontal cortex, left parahippocampal cortex in MHE patients, while functional connectivity increased in the right precuneus.

但与正常对照组相比，MHE患者大部分脑缺省模式网络脑区功能连接降低，包括：左侧后扣带回、双侧前扣带回、双侧额中回、左侧海马旁回；而右侧楔前叶的功能连接较正常对照组升高。

On the contrary, more significant activations by English familiar voices were observed in the left precuneus, middle frontal gyrus and left posterior cingulate cortex as compared with Chinese familiar voices; For Chinese unfamiliar voices, more significant activations were observed in the right middle temporal gyrus and right medial frontal gyrus than for English unfamiliar voices.

结果： 汉语熟悉声音较英语熟悉声音显著激活脑区位于右颞上回；英语熟悉声音较汉语熟悉声音显著激活脑区位于左楔前叶、额中回和左后扣带回；汉语不熟悉声音较英语不熟悉声音显著激活脑区位于右颞中回和右额叶；英语不熟悉声音较汉语不熟悉声音位于右额下回、额中回和左颞中回。

A significant negative linear correlation between clonidine concentration and rCBF or spindle activity was observed in the thalamus, prefrontal, orbital and parietal association cortex, posterior cingulate cortex, and precuneus.

统计学分析后，发现在丘脑区、前额叶、眶上回及顶叶联合脑区大脑皮质、背扣带回大脑皮质、楔前叶，可乐定浓度与区域脑血流（ rCBF ，即脑电图出现梭形波）呈统计学意义的负线性相关关系。

Results①Compared to NC,PD patients showed decreased positive functionalconnectivity in right dorsolateral prefrontal cortex and bilateral posteriorcingulate cortex related to bilateral STR.In addition,left parietal posteriorcortex (including precuneus,inferior parietal lobule,supramarginal gyrus) showeddecreased positive functional connectivity with L-STR.

结果①PD患者与双侧STR正连接减弱的区域主要位于右侧前额叶背外侧部(dors-olateral prefrontal cortex，DLPFC)和双侧后扣带回皮质(posteriorcingulate cortex，PCC)，此外，左顶叶后部皮层(左侧楔前叶、顶下小叶、左侧缘上回)显示与L-STR正连接减弱。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
