1
Your nerves are literally everywhere around here.
2
We'll start from the most important ones,
3
which are going through your spine and your brain.
4
This thick cluster of nerves is called the central nervous system, or CNS.
5
It's responsible for everything you do,
6
from breathing to tapping your finger on the side of your smartphone while waiting until I get to the topic already.
7
When a signal gets to the CNS in the brain from any part of the body,
8
it sends back a command to react according to the situation.
9
Pinch yourself now.
10
Yeah, please do it.
11
Ow!
12
The place you've just pinched has a lot of neurons,
13
just like anywhere else.
14
When you pressed the skin,
15
they flared up and sent the information about pain to the brain,
16
which reacted by sending back a message that it hurt.
17
It all happened in less than a millisecond,
18
but the signal traveled several feet there and back.
19
Let's go to the spinal cord now and carry out a little experiment.
20
On the count of one,
21
I'll sever the connections between the neurons here and you'll see what happens.
22
Ready?
23
One.
24
See?
25
You've just become limp from your waist down and can't feel anything in your legs.
26
It's because your CNS can't figure out where they are.
27
Okay, restoring the connections now, don't worry!
28
This is why both your brain and spinal cord are naturally protected by bones,
29
the skull and the vertebrae.
30
Inside the spinal column, there's also cerebrospinal fluid,
31
a liquid substance that protects the nerves,
32
helps better conduct signals, and gets rid of weights.
33
Ok, now let's take a closer look at all the rest of the nerves,
34
starting with the ones at the tips of your fingers.
35
Something that's not the CNS is called peripheral nervous system, or PNS.
36
Will you kindly wave your hand now?
37
Thanks!
38
You've been able to do that because your brain consciously sent several million signals to the peripheral nerves in your shoulder,
39
forearm, wrist, and hand.
40
Together, they made a common effort to lift your arm,
41
fix it in a certain position,
42
and wave the hand from side to side.
43
And responsible for this effort is your voluntary or somatic nervous system.
44
Your eyebrows going up at this fact are also controlled by the same nerves.
45
Did you count how many breaths you took while listening to my ramblings?
46
a beat your heart had made.
47
You shouldn't have.
48
These things are regulated by your vegetative or involuntary nervous system.
49
Your CNS sends signals to the periphery and tells your heart to beat,
50
your respiratory system to let the air in and out,
51
and even your bowels to digest the food you eat.
52
Now, blow all the air out of your lungs and hold your breath for as long as you can.
53
Okay, this will take some time,
54
so fast-forward to the point where you start wanting to breathe in.
55
Letting the air out and holding your breath are your conscious actions,
56
so it's you who tells your brain to send signals to the breathing organs.
57
But when you start lacking oxygen,
58
it's already your brain that tells you to stop fooling around.
59
Oh, I see you're becoming blue in the face.
60
Please inhale already.
61
And now I'll do something you'll have to forgive me for.
62
Ow!
63
Sorry, you dropped the phone because I sent a little shock through it.
64
The point is, you subconsciously let your phone go as soon as you felt the pain.
65
When I asked you to pinch yourself,
66
you activated your voluntary nervous system,
67
so you expected the pain and could continue pinching if you wanted to.
68
This shock came unexpectedly, though,
69
so your involuntary nervous system jolted in and made you move away from the threat ASAP.
70
That said, your self-preservation instinct is something that's regulated by your nerves as well.
71
Your body will try to save itself from harm even without your consent.
72
Hey, what's that itch?
73
You need to scratch it now.
74
Thanks.
75
Itching appears when there's something on or under your skin that doesn't belong there,
76
like an insect or a bite it left.
77
Nerves at the site flare up like beacons,
78
and your brain sends signals to that spot.
79
But when you scratch the itch,
80
you feel two opposite things at once.
81
Consciously, you experience relief because it's not itching anymore.
82
On the subconscious level, though,
83
your brain perceives scratching as pain and shifts your attention from the itch to the scratch instead.
84
Basically, by scratching, you trick your brain into believing there are more important things to do than paying attention to the itch.
85
Hey, is it me or is it a bit too hot here?
86
Yeah, I see droplets of sweat on your forehead.
87
When the outside temperature rises,
88
your CNN reacts to the change.
89
Billions of signals flash through your entire body.
90
Sweat glands receive them in the blink of an eye and start working furiously.
91
Sweat appears on your skin, cooling it down.
92
I recommend going to the AC and turning it higher a bit, thank you.
93
Hey, I said a bit,
94
not all the way up.
95
Ah, great, now you're shivering.
96
Your brain is confused but is still working fast,
97
reacting to the change of circumstances.
98
Once again, it sends billions of signals to all the neurons in your muscles,
99
telling them to start contracting as quickly as they can.
100
By doing so, they create friction, and friction generates heat.
101
Your heart starts beating faster too,
102
by the way, pumping blood to your limbs to keep them from freezing.
103
All this also makes you think sliding that counter up a notch is a good idea.
104
On the topic of thinking,
105
neurons are responsible for that too.
106
For example, this is your first time watching this video video.
107
You can't possibly know what I'm going to do or say next.
108
Maybe I'll do a barrel roll.
109
Or just end the whole video abruptly.
110
Your brain is only now creating the neural connections necessary for you to remember what's coming up next.
111
This is why you're still bearing with me.
112
You want to know.
113
But as soon as you've watched it until the end,
114
the interest is gone, no matter how fascinating I am.
115
Your CNS has created enough connections between the neurons,
116
and if you start over,
117
they will tell you what to expect.
118
Still, the pathways are very basic.
119
A simple example.
120
What did I say exactly 3 minutes and 5 seconds into the video?
121
You can't remember, because your neural connections aren't strong enough yet to give such details.
122
But the more times you watch,
123
the stronger and more numerous they become,
124
and after a number of attempts,
125
you'll be able to repeat the whole text word for word.
126
The same happens when you learn some new skill, like roller skating.
127
At first, you can't move even a single foot.
128
Your brain encounters an unusual task and is all ablaze with signals it's sending every which way.
129
You fall, but then you stand up and try once more.
130
This time, several million neurons are already connected,
131
and your CNS doesn't waste time creating new links.
132
You fall again, and again, and again.
133
But every time you rise and repeat,
134
your brain gets more and more adapted,
135
until finally, on your 5th,
136
10th, or 50th attempt, you skate forward.
137
The brain captures the moment you stop falling and creates strong neural connections to prevent you from repeating your previous mistakes.
138
And soon enough, with more practice and links in your CNS,
139
you'll be skating like a pro,
140
wondering how you could be so clumsy before.
141
Yet, the best thing about these connections is that they never completely go away.
142
Even if you learned skating as a kid and then didn't put on the skates for 10 years,
143
it'll take you just a couple of minutes to recall how it's done.
144
So hey, if you're afraid to take that dusty guitar hanging on the wall for years, don't be.
145
Go strum the strings, it'll all come back to you in a jiffy.
146
Maybe not the calluses.

맥락 및 배경

이 비디오는 신경계의 작동 방식을 설명하며, 우리의 몸에서 어떤 일이 일어나는지를 보여줍니다. 강연자는 신경의 기본 구조와 중앙 신경계(CNS)와 말초 신경계(PNS)의 차이점을 설명합니다. 이를 통해 신경 신호가 어떻게 신경망을 통해 전달되고, 우리의 의식과 무의식적인 행동이 어떻게 조절되는지를 자세히 다룹니다.

일상 대화를 위한 5가지 주요 표현

  • 신경이 나에게 신호를 보낸다. (The nerves send signals to me.)
  • 감각을 느끼다. (To feel a sensation.)
  • 내가 꼬집었을 때. (When I pinched myself.)
  • 움직이기 위해 신호를 보내다. (Send signals to move.)
  • 조정이 필요하다. (Adjustment is required.)

단계별 쉐도잉 가이드

비디오의 복잡한 내용을 이해하고, 영어 발음을 교정하기 위해서는 다음과 같은 쉐도잉 기법을 따르는 것이 좋습니다. 영어 쉐도잉을 통해 shadowspeak 기술을 연습하면 발음과 억양을 자연스럽게 개선할 수 있습니다.

  1. 첫 번째 단계: 비디오를 처음부터 끝까지 시청하며 전체적인 내용을 파악합니다. 이 단계에서 신경계의 기본 개념을 이해하는 것이 중요합니다.
  2. 두 번째 단계: 두 번째 시청을 하면서 각 문장을 천천히 따라합니다. 이때 shadow speech 방법을 사용하여 발음을 정확하게 따라하려고 노력합니다.
  3. 세 번째 단계: 복습을 위해 비디오 속 표현을 반복해 보세요. 일상에서 활용할 수 있는 표현들을 통해 자연스럽게 자신의 어휘를 확장할 수 있습니다.
  4. 네 번째 단계: 길고 복잡한 문장은 컷으로 나누어 연습합니다. 이 과정에서 자신의 목소리를 녹음하고 들어보며 개선점을 찾아보세요.
  5. 다섯 번째 단계: 자주 사용하는 말들을 정리해보면서, 자신의 목소리와 발음의 차이를 체크합니다. 영어 발음 교정을 위해 반복적인 연습이 필요합니다.

이와 같은 방법으로 shadowspeaks 기법을 활용해 본다면 영어 회화 실력이 눈에 띄게 향상될 것입니다. 영어 쉐도잉을 지속적으로 연습하여 더욱 유창하게 소통해보세요!

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
