楔叶前的

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。

Moreover, during the behavioral judgment task, salient activation of bilateral Precuneus was found when participants judged the actresses' behaviors which were congruent with the gender stereotype rather than the incongruent behaviors.

同时在行为判断阶段，被试对女性模特符合性别刻板印象的行为比违反性别刻板印象的行为显著地激活了双侧顶叶/楔前叶，同样对于男性模特的刻板印象行为判断没有显著区别。

In particular, it is unknown how the relevant neural substrates function as a network to mediate perspective-taking during the task requiring understanding other's belief. The current work first developed a new psychological paradigm that excludes potential confounds such as the processing of language, biological motion, episodic memory and causal coherence in the paradigms used in previous studies. I recorded neural activities associated with mental inference task using functional magnetic resonance imaging and electroencephalography in order to investigate the functional roles of several brain areas (i.e. precuneus, MPFC, etc.) that engage in understanding other's belief. I also proposed a computational model based on the neuroimaging results that simulated the neurocognitive mechanism underlying cortical dynamics in correct judgment of other's belief.

本文首先发展了一个新的心理学实验范式，排除以往常用&错误信念&范式中与语言加工、生物运动、情景记忆及事件连续性和因果性等方面的混淆，采用功能磁共振成像（functional magnetic resonance imaging， fMRI）和脑电（Electroencephalography， EEG）时频分析等脑成像技术，记录与理解他人信念任务相关的神经活动，通过对行为和脑成像数据的分析，研究楔前叶和内侧前额叶等脑区在理解他人信念任务中的功能意义，并根据脑成像结果，提出一个基于自我和他人视角竞争的计算模型，模拟大脑在理解他人信念时做出正确决策时的认知神经机制。

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。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
