1 .listen to a conversation between a student and a professor.
该句暂无译文！
2 .So John, what can I do for you?
该句暂无译文！
3 .Well, it\'s about the stuff you talked about yesterday, about the research on the brain.
该句暂无译文！
4 .Okay. Well, one thing was that experiment where two groups of people were learning to play a finger exercise on the piano.
该句暂无译文！
5 .If I understood you correctly,
该句暂无译文！
6 .one group actually practiced the exercise on the piano, and the other group, they didn\'t move their hands. They just kind of imagined, visualized
该句暂无译文！
7 .how their fingers would move on the piano.
该句暂无译文！
8 .That\'s right. And each group did that every day for five days,
该句暂无译文！
9 .two hours a day.Okay, so I did understand that part.
该句暂无译文！
10 .I guess what I wasn\'t clear on was the results of the experiment.
该句暂无译文！
11 .I mean, I don\'t think it was like, you know
该句暂无译文！
12 .that at the end, both groups could play the exercise equally well. That\'s right. No,
该句暂无译文！
13 .what the researchers were interested in
该句暂无译文！
14 .were changes in the brain that took place as a result of the practice,
该句暂无译文！
15 .okay And what they found was that a certain part of the brain, the part that controls your fingers when you\'re playing the piano,
该句暂无译文！
16 .that part had expanded as a result of the practice, and it expanded in both groups,
该句暂无译文！
17 .the group that actually practiced on the piano
该句暂无译文！
18 .and the group that just imagined it
该句暂无译文！
19 .this mental practice they were doing
该句暂无译文！
20 .learning the exercise, was changing the physical structure of a portion of the brain,
该句暂无译文！
21 .rewiring it, expanding it.
该句暂无译文！
22 .It\'s amazing that just thinking could do that could affect the brain like that.
该句暂无译文！
23 .I wonder if that\'s true for sports too
该句暂无译文！
24 .well, the idea that you can improve, say, your performance in a sport by
该句暂无译文！
25 .visualizing it has been around for quite a while, but
该句暂无译文！
26 .I don\'t know that anyone suspected that you were actually altering
该句暂无译文！
27 .the physical structure of your brain when you did it.
该句暂无译文！
28 .I wish that men I could skip basketball practice and just lie around and think about practicing tonight.
该句暂无译文！
29 .Good luck with your coach on that one,
该句暂无译文！
30 .it\'ll still require lots of real practice, physical practice,
该句暂无译文！
31 .but maybe with the mental training, it\'ll require less practice,
该句暂无译文！
32 .or maybe you\'d learn to do it better than with the physical practice alone, okay?
该句暂无译文！
33 .And I had just one other question.
该句暂无译文！
34 .You also made some point about meditation?
该句暂无译文！
35 .Yes, I was talking about a researcher who studied brain activity in some people who\'d been practicing meditation for many years,
该句暂无译文！
36 .and he found out that they, too had, apparently to these many years of meditation practice changed their brains,
该句暂无译文！
37 . patterns connections within their brains.
该句暂无译文！
38 .For instance, they gradually enabled themselves to consciously activate
该句暂无译文！
39 .the left prefrontal cortex, the part of the brain that\'s active when we\'re feeling happy.
该句暂无译文！
40 .So they kind of train themselves to be happy, yes
该句暂无译文！
41 .which is interesting, because usually we think we have to have something, you know, or like,
该句暂无译文！
42 .achieve something to feel happy, but they don\'t need that
该句暂无译文！
43 .good point.
