Scientists Explain Why Taxing Mental Work Wears You Out_我的网站

A |     11月1日，市委书记高键到新宾满族自治县第一中学调研教育工作。    A team of scientists has discovered a likely explanation for why one may feel exhausted after engaging in intense cognitive work.,In their study, published in the Current Biology last week, the researchers argue that intense cognitive work, when it lasts for several hours, results in the buildup of potentially toxic byproducts in the prefrontal cortex part of the human brain, which then affects a person’s behavior.,“Influential theories suggested that fatigue is a sort of illusion cooked up by the brain to make us stop whatever we are doing and turn to a more gratifying activity,” Mathias Pessiglione of Pitié-Salpêtrière University in Paris, said as quoted in a news release by Cell Press. “But our findings show that cognitive work results in a true functional alteration—accumulation of noxious substances—so fatigue would indeed be a signal that makes us stop working but for a different purpose: to preserve the integrity of brain functioning.”,During the course of their research, the team employed magnetic resonance spectroscopy to monitor the brain chemistry of two groups of people during a workday, with one group performing easy cognitive tasks while the other engaged in more complex mental activities.,Only the latter group ended up exhibiting signs of fatigue, as well as a tendency to favor “options proposing rewards at short delay with little effort,” as the news release put it.,AmericasChild Survives After 7 Minutes Without Blood Flow to Brain During Surgery, US Cardiologist Reveals11 August, 16:41 GMT,Furthermore, members of that group had higher levels of glutamate in the synapses of the prefrontal cortex, leading the researchers to suggest that the accumulation of glutamate “makes further activation of the prefrontal cortex more costly,” and thus a mentally exhaustive workday makes cognitive control more difficult.,Unfortunately, there seems to be no fancy way to deal with this problem other than the tried and tested method that is probably as old as history itself.,“I would employ good old recipes: rest and sleep!” Pessiglione remarked. “There is good evidence that glutamate is eliminated from synapses during sleep.”。他强调，要深入学习贯彻习近平总书记关于教育的重要论述和党的二十届三中全会精神，聚焦教育强市目标，补短板、强弱项、提质量，用心用情办好人民满意教育，为实现抚顺全面振兴新突破提供有力支撑。         　　在新宾满族自治县第一中学，高键实地查看校园基础设施建设，详细了解学校办学理念、师资建设、教学质量和校园安全等情况，随机走进教室，与师生进行互动交流。他勉励学生，要树立远大理想，刻苦努力学习，培养优良品德，锻炼强健体魄，努力成为堪当民族复兴大任的栋梁之材。叮嘱教师，要落实立德树人根本任务，时刻以教育家精神为标尺，坚持教书与育人相统一、言传与身教相统一，注重因材施教，努力培养更多全面发展的高素质学生。         　　在调研中，高键围绕教育强市建设，认真倾听大家意见建议。他强调，要深入学习贯彻习近平总书记在全国教育大会上的重要讲话精神，牢牢把握教育的政治属性、人民属性、战略属性，更加重视和优先发展教育事业，充分发挥教育在服务抚顺产业升级、社会转型、城市发展中的先导作用，用高水平教育吸引人、留住人、发展人。要坚持办好人民满意教育，以人民为中心、以问题为导向，持续深化教育领域综合改革，优化区域教育资源配置，扩大优质教育资源供给，加强学校设施建设，建强师资队伍，全面激发学校活力动力，不断提升办学质量和水平。要高度重视校园安全管理，扎实抓好食品安全、消防安全、校车安全等工作，加强校园周边环境治理，确保广大师生人身安全，营造平安有序的教育环境。         　　新宾满族自治县相关负责人参加调研。                   责任编辑：刘春阳。
