What are the basic modules, what information needs to be passed between those modules in order to make the code work.
基本的模块是哪些,为了让整个程序正常运行,这些模块之间需要传递的信息有哪些。
We've then talked about how neurons can communicate to one another; then, turned to how neurons are wired up together.
接着我们还讲了,神经元之间是如何进行信息传递的,之后,我们又谈到了,神经元是如何连结在一起的
Well, if you're implementing a computer that needs to represent information now all you need is something like electricity which can be on or off, on or off.
好吧,如果你正用一个电脑,来表现表达传递信息的功能,你就需要,像电开关一样的物体。
That just allows information to move more quickly from one end of the cell to the other.
鞘磷脂使信息更快地,从细胞一端传递到另一端
And there is Owen, in uniform, a handsome young man. This is all, as I say, very much part of the transmission of Owen's poetry.
这是欧文,穿着制服,这样一个帅气的年轻小伙,我说过,这都是欧文诗篇中传递出的信息。
Now because it is so important to understand how the neurons present the information, ? let me go into a bit more detail. Ok?
既然要理解,神经元传递信息是如此重要,我来更加详细地解释一下,好吧?
In addition, in terms of conveying content, we prepared a notebook, where we had all the teaching materials that Professor Low used in this lecture on paper.
另外,从传递信息而言,我们准备了一个笔记本,其中包括Low教授课上,用到的所有教学资料。
Then that information - that integrated information is passed onto another cell through the axon.
然后信息 - 整合好的信息,通过轴突传递给下一个细胞
The ligands are bringing some message, they transmit the message by binding to the receptor.
配体带有一些信息,它们通过与受体结合来传递这些信息
And you're going to deliver this now.
你将传递这样一个信息。
If you hear about signal transduction in biology, people that study signal transduction are studying just these things we talked about, how biochemical messages get transferred into cells and through cells.
如果你在生物学领域听到信号转导这个词,那么研究信号转导的人就是,在研究我刚才讲过的那些东西,生化信息如何传入细胞并传递至细胞各处
So, neurons communicate to one another chemically.
这样,神经元之间便通过化学方式,进行信息的传递
Because these molecules can span across the membrane from outside to inside, they're in just the right position to take messages that they receive from outside the cell and transmit them through the membrane into the cells internal apparatus, and that's what they do.
因为这些分子能穿过细胞膜,连通细胞内外,它们所在的位置非常适于接受信息,它们能将外界获得的信息,通过细胞膜传递给细胞器,这正是它们的功能
Now, neurons are connected and they talk to one another and it used to be thought they were tied to one another like a computer, like you take wires and you connect wires to each other, you wrap them around and connect them.
神经元之间是相互联系的,它们彼此间存在信息的传递,人们曾经以为它们是被绑在一起的,就像计算机,就像是你要把所有的电线接在一起一样,你把电线缠起来,连在一起
It doesn't work that way for a variety of reasons, but the main reason is that you want some decisions to be made at each space between two cells.
这出于很多原因,但主要的原因是,在每个细胞间隙,都需要决定信息是否继续传递
The way that they communicate with each other is by physically touching each other, and the way that they connect across distances is by having these process that extend from one place to another.
它们通过物理接触,来交换信息,神经之所以能跨距离传递信息,就是靠细胞间互相延伸的突起
Well, the mechanism that the cell uses to transmit information along itself, along this process which goes from my brain to my fingers, for example, is through an electrical signal called an action potential.
神经细胞沿突起,将信息从我的大脑传递到,手指的机制是,举例来说,是通过一种称为动作电位的电信号的作用
We look out, we see where we like to go, we know where our arms are at, we take that information to the rear part of the brain, they were within visual, which start forming initial plans to move our arms, we elaborate those plans.
我们去看外界,我们看到自己想去的地方,我们知道自己胳膊的所在,我们将这一信息传递给大脑后面,负责视觉的部分,该部分开始为我们移动胳膊制定最初的计划,我们详细描述这些计划。
It indicates how information flows in cells and indicates a lot about the work that a cell does in maintaining and recreating itself, and maintaining its environment.
这个图展示了信息如何在细胞内传递,以及细胞,在维持 复制自身,和维持其周围环境所需起的作用
One class of them is beta-blockers, they bind to beta-adrenergic receptors, which are receptors that exchange information between your nervous system and the contractile system that beats your heart and that causes the heartbeat.
一类药物是β阻断剂,它们与β肾上腺素受体结合,这种受体能够在神经系统和,控制心跳的心肌收缩系统之间传递信息,从而产生心跳
We're going to talk in some detail, not a very high level of detail, but in some detail about how this communication takes place between cells and how the information is passed down one of these cells today.
我们还要讨论些细节问题,但不是太深,今天只讲细胞间通讯的发生原理,和信息怎样从一个细胞传递到另一个细胞
