访谈录[Interview]2007-11-28:睡觉时,你的大脑在干吗?

Speaking of medicine, when you go to sleep at night, think you are getting you a good night, while you sleep your body maybe resting but guess what your brain is really in many ways working overtime 1 as a new study up researchers in airs on that shows, a brain is replaying your days’ activities. Doctor Mark Sable 2 is from the New York university school of medicine to help to understand what does this means for our sleep and our lives, doctor happy thanks giving, thanks for being with us do you believe the study and does it match what we know in the stands that we made in neural 3 science?

Happy thanks giving Greg, it does actually it’s a very exciting study you know neural science has being hidden in this direction, this is the brain in real time, this is what happens when the brain is not encumbered 4 by our daily editor, which says you know during the day we are full of traffic, our brain is full of traffic, we have to go wonder action or another/at night all that ‘s gone, so it’s kindda like going along on highway without a lot of traffic to slow you down, and we get to replay what we were on during the day and we get the consolidate/we get to putting things in a certain order going forward, the old memories with the new, this is very much in keeping with what was the latest neural science have been shown.

We were just looking a moment ago at a image of the brain, how are we able to map this

Well you know we have some very new techniques for this which is very exciting we have a more eye scans now that calls Quantitate, they look at the amount of chemicals on the brains they can measure electrical activity, we are much better at telling what electrical activity is coming from where, the part of the brain we are talking about here is the very front of the brain, the pre-front of the context in a very very/in tip of the brain, this is where/some of the most sophisticated behavior memory and motion go on.

Well what happens doctor when we sleep are we reprocessing information I mean I think that all of us who are in a weak in the middle of the night with the idea or sort of the pithiness 5 of the days event.

Well you know Greg, we like to think of sleep, as in rejuvenating 6 time, a time when we really get our energy, and I don’t want to take it away from that course that’s crucial, but it looks like there is a second thing going on during that time, when we do repress information almost regard to take it go through a different way, we get to access part to the brain that we can’t access when we suppress during the day, we pull over our most exciting and interesting thought together in ways that we can’t do when we do when we distract during the day.

You know I read long ago the deprivation 7 leads to neural our function say got to have sleep you got to have enough, you know it’s individual time table, we leave that for another time doctor Mark Sable , thanks so much again, happy ya thanks giving.

Thanks Greg, thanks having me on. Ok.
