During the BDST task, areas showing activation in healthy volunteers include bilateral middle frontal gyrus, left superior frontal gyrus, inferior frontal gyrus, precentral gyrus, superior parietal lobe, suprarnarginal gyrus, Inferior temporal gyrus and occipitotemporalis lateralis gyrus, however, the left superior frontal gyrus, inferior frontal gyrus and bilateral posterior parietal cortex in schizophrenic patients showed significantly less activation.

在＊M河的侧m检查中治疗后，IA亚组的左侧额上回及左侧额下口的激活低下明显改善（P＜O.05），H A亚组的左恻额上回及左侧额下回的激活低下明显改善P＜O刀5），右侧领下回的激活降低（P＜0.05）。结论门）首发精神分裂症患者在发病初期就存在认知缺陷症状，工作记忆等与前额区相关的功能缺陷是普遍而严重的。

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。

Results:The results largely conformed to previous studies and further confirmed the role of hippocampus, precuneus and posterior cingulate cortex in aMCI patients at rest,as well as that of the frontal lobe and medial temporal lobe structures in episodic memory.

在完成情节记忆任务过程中，aMCI患者的额叶、顶下小叶、海马、海马旁回和扣带回的激活较正常人增加；除顶下小叶外，其他区域局部亦表现为较正常人激活降低。

Compared to normal controls, it was found that the hippocampus, temporal pole, frontal lobe, temporal lobe, putamen and precuneus exhibited more significant functional connectivity with posterior cingulate cortex in TLE.

研究发现，与正常对照相比，TLE静息时海马、颞极、额叶、颞叶、壳核及楔前叶等脑区与后扣带回的功能连接增强。

Compared to the controls, the patients exhibited decreased ReHo mainly in the precuneus, medial prefrontal cortex, bilateral middle temporal gyrus and middle frontal gyrus; while the increased ReHo was mainly distributed in the subthalamus.

结果表明：在静息状态下，患者大脑的局域一致性在某些脑区较正常人低，主要集中在楔前叶、内侧前额叶、双侧颞叶、双侧额中回；另外，在某些脑区较正常人高，主要集中在底丘脑等中缝核团。

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。

Result: Compared to normal subjects, some functional regions associated with encoding, maintenance and retrieval process showed increased activation in schizophrenia patients, i.e. right precuneus for encoding process, left PMA, left DLPFC, right precuneus and left VLPFC for maintaince process, left PMA for retrieval process. In addition, subcortical structures, primary motor cortex and some verbal regions in left temporal lobe also showed more activation.

结果：与正常组比较，患者组工作记忆不同认知过程的执行脑区激活程度增加，编码期激活增加脑区为右侧楔前叶，维持期激活增加脑区为左侧PMA、左侧DLPFC、右侧楔前叶及左侧VLPFC，提取期激活增加脑区为左侧PMA，而且患者组还激活了更多皮层下结构、初级运动皮层及左侧颞叶语言相关脑区。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
