【文章內(nèi)容簡(jiǎn)介】 wer motor neuron out to your muscles here, and that electrical discharge is going to be picked up by these electrodes right here and weamp。39。re going to be able to listen to exactly what your brain is going to be doing. So Iamp。39。m going to turn this on for a second.
其實(shí)，此時(shí)此刻在你的大腦內(nèi)有800億神經(jīng)元，它們?cè)趤砘匕l(fā)送電信號(hào)和化學(xué)信號(hào)。但在這里有一些位于你的運(yùn)動(dòng)皮質(zhì)的神經(jīng)元，你這樣運(yùn)動(dòng)胳膊的時(shí)候會(huì)向下發(fā)送信號(hào)。這些信號(hào)會(huì)向下穿過胼胝體，進(jìn)入你的脊髓，到達(dá)下運(yùn)動(dòng)神經(jīng)元，再到達(dá)你這里的肌肉，這種電信號(hào)釋放會(huì)被這里的電極接收，于是我們就能夠聽到你的大腦到底想要做些什么。我來打開這個(gè)東西。
Have you ever heard what your brain sounds like? SK: No. GG: Letamp。39。s try it out. So go ahead and squeeze your hand. (Rumbling) So what youamp。39。re listening to, so this is your motor units happening right here. Letamp。39。s take a look at it as well. So Iamp。39。m going to stand over here, and Iamp。39。m going to open up our app here. So now I want you to squeeze. (Rumbling)
你有聽過你的大腦的聲音嗎?SK：沒有。GG：來試試吧。來試著抬肘握一下拳。(隆隆聲)你現(xiàn)在聽到的，這就是你的運(yùn)動(dòng)單元正在此處發(fā)揮作用。我們也來看一下好了。我會(huì)站在這里，我需要打開我們的應(yīng)用程序?，F(xiàn)在握一下拳，(隆隆聲)
So right here, these are the motor units that are happening from her spinal cord out to her muscle right here,and as sheamp。39。s doing it, youamp。39。re seeing the electrical activity thatamp。39。s happening here. You can even click here and try to see one of them. So keep doing it really hard. So now weamp。39。ve paused on one motor action potential thatamp。39。s happening right now inside of your brain.
就在這兒，這些就是正在起作用的運(yùn)動(dòng)單元，從她的脊椎延伸到這里的肌肉，伴隨著她的動(dòng)作，你可以看到這里的電信號(hào)活動(dòng)。你甚至可以點(diǎn)進(jìn)去看其中的一個(gè)。繼續(xù)不停地使勁握拳。我們現(xiàn)在暫停在此時(shí)此刻正在你腦內(nèi)的一個(gè)運(yùn)動(dòng)電勢(shì)。
Do you guys want to see some more? (Applause) Thatamp。39。s interesting, but letamp。39。s get it better. I need one more volunteer. What is your name, sir? Miguel Goncalves: Miguel. GG: Miguel, all right. Youamp。39。re going to sta
