英语翻译
Effect of prolonged stimulation on cerebral hemodynamic:a time-resolved fNIRS study.
PURPOSE:Sustained attention is one of the most important cognitive abilities for the management of everyday life,but it is often studied only at the behavioral level,while functional correlates are scarcely investigated.In this article,the authors address the topic of characterizing the dynamics of cerebral metabolism in the prefrontal cortex during a task of prolonged attention.METHOD:By means of multichannel time-resolved functional near-infrared spectroscopy and generalized linear model based data processing,the authors measured the hemodynamic response of the prefrontal cortex from 19 healthy subjects to a shortened version of a sustained attention task (Conners' Continuous Performance Test),lasting for 10 min.RESULTS:The task elicited significant brain activation,which did not remain constant for the entire task,but showed a drop not correlated with performance decay 4 min after the beginning of the task.Furthermore,oxygenated hemoglobin showed an increasing trend also during the first phase of the recovery,just after the end of the task.CONCLUSION:The results indicate a nontrivial dynamics of neural activation,habituation processes,and hemodynamic/metabolic coupling.These results encourage further studies about continuous stimulation of cognitive functions on both healthy and pathological subjects.
我自己翻译出来的有些怪异,标题和摘要
是healthy management方面的.

延长对大脑血液流动刺激的效果：fNIRS（这个是我查不到是什么 呵呵）time-resolved 时间分辨
PURPOSE:Sustained attention is one of the most important cognitive abilities for the management of everyday life,but it is often studied only at the behavioral level,while functional correlates are scarcely investigated.In this article,the authors address the topic of characterizing the dynamics of cerebral metabolism in the prefrontal cortex during a task of prolonged attention.
目的:长时间集中注意力是日常生活管理的一相重要的认知能力,然而它却常常作为行为范畴来研究,在功能方面却鲜少涉及.在本篇文章里,作者通过延长注意力来阐述了脑代谢动力学在脑额叶皮层时所具有有的特征.
METHOD:By means of multichannel time-resolved functional near-infrared spectroscopy and generalized linear model based data processing,the authors measured the hemodynamic response of the prefrontal cortex from 19 healthy subjects to a shortened version of a sustained attention task (Conners' Continuous Performance Test),lasting for 10 min.
方法：作者通过采用多通道时间分辨功能近红外光谱,广义线性模型的数据处理的模式,对19个健康的受试者进行脑额叶前部皮层的测量实验（测试者的连续性能实验）,发现注意力集中能维持十分钟.
RESULTS:The task elicited significant brain activation,which did not remain constant for the entire task,but showed a drop not correlated with performance decay 4 min after the beginning of the task.Furthermore,oxygenated hemoglobin showed an increasing trend also during the first phase of the recovery,just after the end of the task.
结果：这个实验表明对脑部刺激的重大意义.虽然刺激在整个实验中没有一直维持着,但它显示了那一小滴与实验开始后那四分钟的衰退现象没有联系.不见如此,在实验结束后的第一阶段恢复中,氧合血红蛋白一直呈现上升趋势.
CONCLUSION:The results indicate a nontrivial dynamics of neural activation,habituation processes,and hemodynamic/metabolic coupling.These results encourage further studies about continuous stimulation of cognitive functions on both healthy and pathological subjects.
结论：这个结果显示了一个不平凡的神经活化动力学,习惯化进程和血液动力学代（代谢耦合）.这些成效将进一步激励着我们对感知功能在健康与病理项目中的不断地深入研究.
ps：哎,毕竟不是这个专业,对生物不了解.尽力翻译了这一段.

在脑刺激效果的持续时间分辨fNIRS血流动力学:学习。


目的:持续关注一项最重要的认知能力的日常生活,但是它往往是研究只在行为的水平,而执行功能障碍是几乎没有调查。在这篇文章中,作者说明表征的脑代谢动力学在脑额叶前部皮层在一个任务的注意。方法:采用多功能性近红外光谱分析和概括时间分辨线性模型的数据处理中,作者测量脑额叶前部皮层血流动力学响应来自19个健康的受试者,缩短的版本的持续性注意力的任务(Conners '连续性能测试),持续10分钟。结果:任务时,大脑活性明显不保持不变,整个任务,但是显示下降并不相关,与绩效腐烂4分钟后开始的任务。再者,含氧血红蛋白呈现一种上升趋势还在第一阶段的恢复,就结束后的任务。结论:结果显示一个平凡的神经激活动力学过程,并逐渐充耳不闻,血流动力学/代谢耦合。这些结果鼓励进一步的研究有关的认知功能上不断刺激健康和病理的科目。
