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

A |     本报记者 陈晶涛“东青堡村以现金方式投资温室大棚食用菌项目，投资额为50万元，投资期限10年，截止日期为2030年12月31日……”今年3月，一条财务公开信息出现在南票区大兴乡东青堡村的“阳光三务”平台系统及村里公式栏上。现如今，像这样及时准确的信息公开已经在南票区各村（社区）全面铺开。    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.”。         　　南票区纪委监委将做实“三务”公开作为推进全面从严治党向基层延伸、规范小微权力的有效路径，采取“阳光三务”平台“线上晾”+村（社区）公示栏“线下晒”相结合的方式全方位晾晒基层党务、村务、财务，切实增强各项工作的透明度，让群众心里明明白白、干部心里亮亮堂堂。

B | 自“辽宁阳光三务”上线以来，“谁家因为什么评低保？高龄补贴都是什么评定标准？今年地力补贴和玉米补贴得多少？”这些老百姓最关注的问题都能在“辽宁阳光三务”平台随时查看，充分实现了“人在家中坐，‘三务’指尖来”的转型升级。         　　秉承“三务”公开要与群众急难愁盼、乡村有效治理紧密结合的工作理念，区纪委监委监督推动区财政局和乡村振兴局将2022年以来的民生工程项目和2023年以来乡村振兴项目纳入线上公开并完成村级相关事项录入。此外，为了推进“三务”公开规范化、程序化，区纪委监委还联合区委组织部、区民政局等职能部门组成联合督导组，运用“听、查、看、访”等方式下沉至13个乡镇（街道）查看线上“阳光三务”平台运行及线下公开栏公示情况，现场调度解答疑点难点问题，发现并推动解决问题9个。截至目前，平台审核发布信息50021条，活跃用户达到2395人，反馈处理满意率100%。

C | “下一步，我们将继续创新举措，深化‘三务’公开内容，丰富公开形式，让‘三务’公开真正成为接受群众监督、解决群众诉求的有效‘接口’，不断提升基层治理水平。”区纪委监委主要负责人表示。
