楔叶

高级组儿童珠心算时激活的脑区少且集中，主要位于枕叶（楔叶及舌回）及顶叶（楔前叶及顶下小叶）。

The brain areas activated in the senior group during the mental abacus calculation were fewer and mainly localized in occipital lobe ( cuneus and infracalcarine gyrus ) and parietal lobe ( precuneus and inferior parietal lobule ) .

两组被试儿童在不同的运算任务中几乎均可见枕叶（双侧楔叶）及顶叶（楔前叶、顶下小叶）激活；不同难度的加法运算中亦可见顶、枕皮质的激活。

Occipital lobe ( bilateral cuneus ) and parietal lobe ( precuneus and inferior parietal lobule ) were activated in both groups during addition and subtraction tasks ; and occipital cortex and parietal cortex were also activated in the three calculation tasks with different difficulty levels .

脑干中脑、延桥交界、右侧楔叶（BA18）、左侧小脑表现为葡萄糖高代谢状态（P<0.01）。

Brain stem midbrain , borderline of medulla oblongata and pons cerebelli , right cuneus ( Brodmann area 18 ) and left cerebellum show hypermetabolism state of glucose ( p < 0.01 ) .

第二层次是楔叶类为代表的林下植物；

The second is subordinate layer of communities represented by Sphenophyllales etc.

楔叶铁线蕨的离体快繁。

电针右侧合谷，信号升高区为：右侧额内侧回，左侧额中回，左侧扣带回前部，右侧扣带回，右侧颞上回；信号降低区为：左侧海马回，左侧下半月小叶，左侧楔叶。

EA Hegu on the right induced signal decreases of left parahippocampal gyrus , left inferior semi-lunar lobule . Signal increases of left anterior cingulated , left middle frontal gyrus , right medial frontal gyrus , right cingulate gyrus , right superior temporal gyrus . 5 .

脑成像结果：汉字词提取过程主要的激活脑区包括前额叶、内侧颞叶、前扣带回、前楔叶、旁海马、岛叶、前中央回、颞上回等区域。

The main findings of functional neuro-imaging results were as follows : retrieval process of Chinese words was associated with increased activity in prefrontal cortex , medial temporal lobe , anterior cingular cortex , precuneus , parahippocampal cortex , insula , superior temporal cortex and so on .

值得注意的是：病人组的楔前叶与后扣带回脑区之间的功能连接显著减弱。

What is noteworthy is that functional connectivity in patient groups between precuneus and posterior cingulate cortex is weaker .

粤语额外激活右额上回、右顶下回和左楔前叶。

The additional areas activated by Cantonese were right superior frontal gyrus , right inferior parietal lobe and the left precuneus .

结果显示粤语与普通话共同激活左额下回、右枕中回和右楔前叶。

The results showed that Cantonese dialect and Mandarin both activated the left inferior frontal gyrus , the right middle occipital gyrus and right 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。

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 .

学习后复杂加法任务所显示的激活区域有：两侧枕叶视区、两侧额中回、左侧额下回、左侧中央前回、两侧辅助运动区、两侧顶上小叶和顶下小叶、两侧楔前叶。

In post-learning task , the activities of bilateral occipital lobe ( visual areas ) and middle frontal gyrus , left inferior frontal gyrus , precentral gyrus and bilateral SMA , superior parietal lobule , inferior parietal lobule and precuneus could be observed .

通过计算网络中心化指标，我们还发现楔前叶和扣带回不仅和许多节点存在广泛连接，而且在节点间最短路径中处于枢纽地位。

By computing the centrality indices of the functional network , we find that the precuneus and cingulate gyrus are connected widely with many other nodes in the network , and acted as the hub areas with shortest paths connecting to other nodes .

新激活的脑区有左侧楔前叶，右侧枕叶梭状回。

New activated brain areas include the left praecuneus , and the gyrus fusiformis of the right occipital lobe . 4 . Compared with non-meridians and non-points group , activated brain areas after electro-acupuncture at Quchi Point ( resting state ) are similar .
