We spend nearly a third of our lives asleep. It's vital for our physical and mental health. But, we’re getting less sleep than ever. British neuroscientist Adrian Owen based in Ontario, believes this may be having a serious effect on our brainpower. I joined volunteers at Western University, Ontario, trying out his online test designed to assess reasoning, memory and decision making. To demonstrate how tiredness may affect those, we stayed up until 4am and then had just four hours’ sleep. Most of our scores went down compared to the night before. After a normal night’s sleep my brain was functioning well. The bright orange blobs are areas of increased activity. And this is the scan done after four hours’ sleep. This study should reveal how much sleep we need for our brains to be at their best.
我們生命中近三分之一的時(shí)間都在睡覺(jué)。睡眠對(duì)于我們的身心健康來(lái)說(shuō)至關(guān)重要。但是,我們的睡眠時(shí)間比以往任何時(shí)候都要少。在加拿大安大略省工作的英國(guó)神經(jīng)科學(xué)家阿德里安·歐文認(rèn)為,這一現(xiàn)狀可能正嚴(yán)重影響我們的智力。我加入了安大略省韋仕敦大學(xué)(Western University)的志愿者團(tuán)隊(duì),并試做了這位科學(xué)家設(shè)計(jì)的旨在評(píng)估推理、記憶和決策水平的在線測(cè)試。為了展示疲勞是怎樣影響上述能力的,志愿者們熬夜至清晨四點(diǎn),接著只睡了四小時(shí)。與前一晚相比,大多數(shù)人的分?jǐn)?shù)都有所降低。經(jīng)過(guò)一宿正常的睡眠之后,我的大腦又開(kāi)始有效地運(yùn)轉(zhuǎn)了。這一團(tuán)亮橙色顯示的是大腦活躍度增加的區(qū)域。而這個(gè)圖像是在我們睡了四小時(shí)后掃描的。該研究將給我們揭示要使大腦達(dá)到最佳工作狀態(tài)所需的睡眠時(shí)間。
This Neapolitan mastiff called Martha has been crowned as the World's Ugliest Dog 2017 in California. Martha and her owner Shirley Zindler picked up the $1, 500 prize. The big-jowled crowd-pleaser will now be flown to New York for media appearances. It's the 29th year of the competition, which typically includes lots of dogs that have been rescued from shelters. The contest aims to raise awareness of the adoption of dogs. The animals are loving companions and seem to enjoy the adoration of the fans.
