Oscar Jenni led this work when he was doing post-doctoral with Mary Chriskaton
奧斯卡詹尼領(lǐng)導(dǎo)了這項研究 他當(dāng)時和瑪麗克里斯坎頓一道完成博士后論文
they've done some more work back in the University of Zurich looking at this lounge toodling
他們在蘇黎世大學(xué)開展了很多研究工作 他們觀察了這部分的變化情況
This just highlights at the simplest visual level
他們突出強調(diào)了最簡單的可視部分的變化
if you look at these different sleep about the amount of the slow waves
大家可以看看這些不同睡眠階段的 慢波變化情況
in the same individual at age 12, 10 and 1 and age 14.5 of teen of 5
同樣的試驗對象12歲 10歲和1歲時 14.5歲時
the intensity of slow wave sleep has really diminished a lot
睡眠的慢波強度減弱了很多
The more interesting issue that has been highlighted is that if you model this work
他們還提出了一個更有趣的問題 如果將這個研究結(jié)論做成模型
and Peter Achemann working with this group
彼得艾奇曼和他的團隊
has done some really elegant mathematical work
就做了大量的數(shù)學(xué)模型
That it's actually not the decay or the expression of these slow waves during sleep
青春期 功能發(fā)生變化的 并不是睡眠期間
that changes the function in puberty but in fact the process of building up the pressure
慢波出現(xiàn)了明顯的減少 而是壓力變得越來越大
is this building-up process as...
這是一個逐漸變大的累積過程
the time constant of these that have really changed
它們的時間常量發(fā)生了變化
I'm not gonna go over some complicated things but if you look at the decay time constant
我不打算詳細講解這些復(fù)雜的問題 大家可以看看時間常量的減少情況
it's really the same 2.8 hours and 2.7 hours during sleep
其實沒有多大的區(qū)別 分別是2.8小時和2.7小時
it's the rise time of the wakefulness as the wave of wakefulness builds up
正是蘇醒過程的時間 蘇醒期間的腦電波逐漸發(fā)生變化
that this homeostatic process that seems to change
是這個自我平衡過程發(fā)生了變化
which has some really interesting implications
這產(chǎn)生了一些有趣的后果
LeBourgeois who's also working and collaborating with that group
雷波吉亞 也參與了這項研究
has been looking at the even younger children
他研究的對象是年齡更小的孩子
thinking and modeling how some of these changes are occurring including the shift in puberty
他對他們的變化情況進行了模型分析 包括他們在進入青春期發(fā)生的變化情況
I'm gonna set this aside for a moment
我先把這個問題放一放
and just talk for a minute about the circadian system that has been alluded already
花幾分鐘時間講講作息規(guī)律系統(tǒng) 剛才我們其實已經(jīng)提到了這個問題
as part of the problem for this perfect storm
這個問題也是青春期變化風(fēng)暴的一部分
