这项研究探讨了模拟微重力对大脑血氧饱和度和认知功能的影响。研究招募了65名年轻健康参与者(平均22±6岁,21名女性),让他们先进行30分钟水平仰卧(0°倾斜),随后进行90分钟的-6°头低位倾斜(HDT)测试。研究使用近红外光谱技术监测前额叶皮层的脑氧合水平,并通过电脑版Stroop任务测量认知功能。结果显示,与水平仰卧相比,HDT期间的脑氧合水平显著提高(9.11±1.3 vs 7.51±1.8,p=0.02)。认知测试结果表明,Stroop任务的非执行功能表现在HDT期间保持稳定(652.46±19.3 vs 632.49±14.5,p=0.09),而执行功能任务的反应时间在HDT后显著改善(1058±195 ms降至950±158 ms,p<0.01)。研究发现,特别是在Stroop任务的转换条件下,脑氧合水平增加最为明显,且只有执行功能(转换)部分的认知表现在HDT期间有所改善。这表明短时间的模拟微重力可以增强执行功能,这与研究假设相符,即由于微重力导致的体液向头部重新分布增加了大脑血流和氧合,从而可能提高认知表现。

这两篇文章涉及太空飞行对人类认知和生理功能的影响研究。第一篇《Dynamic ensemble prediction of cognitive performance in spaceflight》(2022)由Tu等人发表在《Scientific Reports》上,研究了太空飞行中认知表现的动态集成预测。第二篇《Molecular and physiological changes in the SpaceX Inspiration4 civilian crew》(2024)由Jones等人发表在《Nature》上,研究了SpaceX Inspiration4平民宇航员的分子和生理变化。这些研究对理解太空环境对人类认知和生理功能的影响具有重要意义,可能涉及头低位倾斜床休息(HDBR)和升高CO2水平等太空模拟条件下的实验。这些研究成果对未来长期太空任务的人员健康管理和任务规划提供了科学依据。
与问题相关的信息提取
从提供的网页内容中,只有两篇研究论文的标题、作者和出版信息,没有详细介绍研究的主要发现、方法或结论。第一篇论文《Dynamic ensemble prediction of cognitive performance in spaceflight》可能与认知功能相关,但网页内容中没有提供关于头低位倾斜床休息(HDBR)和升高CO2对认知功能影响的具体信息。第二篇论文《Molecular and physiological changes in the SpaceX Inspiration4 civilian crew》研究了太空飞行对平民宇航员的分子和生理影响,但同样没有提供与问题相关的具体内容。
