Music Trying to introduce the study of the brain to a bunch of students,
2
I said if understanding everything you needed to know about the brain is a mile,
3
I asked the students how far had we walked in this mile.
4
I got answers, three quarters of a mile, half a mile, someone said a quarter of a mile, and I said I think about three inches.
5
This is unconventional science.

12
You've got to see the wires.
13
What we're trying to understand is how cells in the brain communicate with each other.
14
Every little object in here is a little wire.
15
To keep track of these cells from one section to another, what you'd like to do is kind of color them in.
16
So every one of these colors have no meaning other than to keep track of each object from section to section.
17
What this allows us to do is to generate a wiring diagram based on this.
18
We now know everything about these wires here and from
19
that we can generate all the connections of every cell in that area.
20
Information forces you into this uncomfortable position where you have to kind of say,
21
okay I don't get it but I know that the real world is more complicated than the way I'm thinking about it.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
