Or monitor their brain waves while they sleep
來(lái)監(jiān)控他們睡著時(shí)的腦波變化
their brain wave activity
他們的腦波活動(dòng)情況
whether their eyes are moving or not
是否出現(xiàn)眼動(dòng)
whether or not their muscles are moving
他們的肌肉是否運(yùn)動(dòng)
and we can then use that
通過(guò)這些數(shù)據(jù)
to get a better idea of what kind of sleep stage they are in
我們可以更好的了解他們的睡眠進(jìn)入了哪一階段
older people show flatter, smaller waves
老年人的腦波顯得更平 更小
They also show worse memory
表現(xiàn)出的記憶力也更差
Then these are in fact associated with each other
這兩者之間其實(shí)存在相互聯(lián)系
The smaller, the flatter the wave the worse their memory is
腦波越小 越平 他們的記憶力也就越差
Following sleep we bring them to MRI facility
睡覺(jué)之后 我們對(duì)他們進(jìn)行核磁共振檢查
and scan them while they are performing
讓他們一邊回憶前一晚學(xué)習(xí)的詞語(yǔ)
while they are trying to remember the words they studied the night before
一邊檢測(cè)他們的腦部活動(dòng)
Just frontal part of the brain here
只是看大腦前額部分的變化
that I'm circling right now
也就是我畫(huà)圈的地方
We are also interested in the place called hippocampus
我們還對(duì)海馬狀突起部位感興趣
which is the medial part of the temporal lobes down over here
也就是顳葉的中間部位
Those parts of the brain are important for memory
這幾個(gè)部位對(duì)記憶力非常重要
So we are interested to see how they are active
我們希望看到 當(dāng)她回憶這些詞組時(shí)
when she is trying to remember the word pairs
這些部位的活動(dòng)情況
Now that we know that sleep is important factor for memory
現(xiàn)在我們知道睡眠對(duì)記憶力非常重要
we can try to see if we can target it to enhance it, to improve the memory in older people
我們可以嘗試著通過(guò)有針對(duì)性的治療 提高并改善老年人的記憶力
It's a very important problem
這是個(gè)很重要的問(wèn)題
It's starting to affect a larger and larger part of our population
因?yàn)樵絹?lái)越多的人群受到這一問(wèn)題的困擾
So being part of the research
所以能參與到
that's aimed at trying to improve cognition in older people is a very exciting process
針對(duì)改善老年人記憶力的研究中來(lái) 這是一個(gè)激動(dòng)人心的過(guò)程
