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

A |     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.”。    本篇评级为★★★，主要围绕以下内容展开：                    1、日本事件引发水产板块行情，谨慎操作的抓手或许还是在消费；          2、谷歌迭代大模型，哪些板块受益？                    如有疑问请以音频内容为准，添加妙投小虎哥微信：miaotou515，入群有机会与董小姐进一步交流。

B |                    新闻解读评级说明：五星重磅，四星重要，三星级以下大家选择听。                   1、日本事件引发水产板块行情，谨慎操作的抓手或许还是在消费          今天三大指数基本收平，市场缺少兴奋点，唯一的话题来自“日本冲突事件”：中方宣布暂停进口日本水产品，A股渔业、水产养殖板块瞬间拔地而起，多股拉至涨停。类似戏码历史上演过多次——中日关系一紧张，水产就被制裁，A股便出现“快闪”行情。但持续性永远要打问号：日本对华水产品出口量占中国总消费比重极低，实质替代效应有限，更多只是资金借题短炒，属于“艺高人胆大”或“火中取栗”行情。

C |                    中日短期缓和概率仍在降低。昨日日方代表来华商谈，双方连握手都未成行，中方随即亮出“水产牌”。此举精准打击对方且几无自伤，资本市场立刻发酵。游资追逐之下，普通投资者宜保持警惕。下一步值得想象：中国会否把制裁扩大到日本水果及其他农产品？资本向来喜欢“抢跑”，水果、畜牧、水产等日常消费细分已纳入视野。

D |                    消费大类本就处于“预热期”：          第一，政策有期待——明年或将出台“居民消费率”量化指标；          第二，节日加持——春节旺季只剩一两个月；          第三，价格信号触底——10月CPI分项回暖，日常服务价格抬头，趴地板已久的消费股财报有望修复。                   本文为妙投付费内容，上述仅为摘要，购买本专栏即可解锁完整内容。新用户可免费领本专栏7天阅读体验机会，在妙投APP-我的-权益兑换 输入“妙投888”即可领取。
