their brain wave activity

and we can then use that
通过这些数据
to get a better idea of what kind of sleep stage they are in

这两者之间其实存在相互联系
The smaller, the flatter the wave the worse their memory is

Following sleep we bring them to MRI facility
睡觉之后 我们对他们进行核磁共振检查
and scan them while they are performing

一边检测他们的脑部活动
Just frontal part of the brain here

So we are interested to see how they are active
我们希望看到 当她回忆这些词组时
when she is trying to remember the word pairs

Now that we know that sleep is important factor for memory

we can try to see if we can target it to enhance it, to improve the memory in older people

It's starting to affect a larger and larger part of our population

that's aimed at trying to improve cognition in older people is a very exciting process
