1
On a fateful day in 1848,
2
Phineas Gage, a 25-year-old American construction worker,
3
was supervising a controlled explosion on a railroad track when an iron rod shot up,
4
going right through his skull.
5
Although he was unconscious for a minute or so,
6
he woke up and was soon sitting upright and talking.
7
How did he survive this traumatic brain injury?
8
How did it change his life and his personality?
9
And what did Gage teach us about the brain's remarkable ability to adapt and recover?
10
Our brain is incredibly powerful.
11
Billions of neurons form trillions of connections,
12
carrying our thoughts as tiny electrical signals.
13
And when those connections get disrupted as a result of an injury,
14
the brain can sometimes, to an extent,
15
rewire itself in a process called neuroplasticity.
16
So what happened to poor Phineas Gage?
17
Well, once he'd woken up,
18
he was taken to the nearest town.
19
And there he was treated by a Dr. John Harlow.
20
We know from Dr. Harlow's notes that the rod removed a chunk of Gage's brain,
21
the right frontal lobe responsible for behavior, emotion, and attention.
22
Gage's health soon deteriorated so much that his family altered a coffin, fearing the worst.
23
But he pulled through, and soon enough he was back to normal.
24
Except he wasn't.
25
He had changed as a person.
26
So much so, his friends and family said that Gage was no longer Gage.
27
This once reportedly organized, reliable,
28
and courteous man became rude,
29
capricious, and as Dr. Harlow put it,
30
a child in his intellectual capacity.
31
While our personality is determined by many factors,
32
including our genes and the environment we grew up in,
33
the area of the brain most associated with it is the frontal lobe,
34
the part destroyed by the rod in Gage's case.
35
You could think then that this change was irreversible and that Gage,
36
as everyone had known him, was gone forever.
37
But was he?
38
In fact, Gage recovered at least some,
39
if not most, aspects of his personality.
40
After the accident, he moved to Chile and retrained as a stagecoach driver.
41
Driving a six-horse carriage required a lot of cognitive effort.
42
He had to memorize a mountainous route with its dangerous twists and turns,
43
and steer each horse's reins separately while navigating crowded roads with a coach full of passengers.
44
He followed the same routine each day,
45
caring for the horses, driving, collecting fares.
46
He likely picked up some Spanish too.
47
This regular, repetitive activity was in a way a version of modern-day neuro-rehabilitation.
48
Every part of our body is connected to a specific part of our brain's outer layer called the cortex.
49
And when the brain experiences traumatic injury,
50
it can sometimes adapt by reallocating functions to a different area.
51
This is called cortical remapping.
52
Gage is often referred to as the man who started neuroscience,
53
because his case was the first to point us towards this knowledge.
54
We once thought that after childhood the brain remains fixed for the rest of our lives.
55
But now we know that our brains are in fact amazingly flexible and the activity in the brain never stops.
56
Brain injury is currently the leading cause of disability worldwide,
57
but neuroplasticity offers some hope for recovery.
58
The fact
59
that our neural connections remain flexible can also contribute to our
60
understanding of how we treat mental health problems such as anxiety or obsessive compulsive disorder.
61
But it's not an easy process.
62
Neuroplasticity relies on regular practice and repetition,
63
sometimes over a very long period of time.
64
Nowadays, neuro-rehabilitation encompasses a range of therapies,
65
helping people to reconnect with lost skills and to restore their emotional balance.
66
Many rehabilitation centres also incorporate music therapy.
67
Music engages various regions of the brain simultaneously,
68
including those responsible for movement, language, memory and emotion.
69
And all this helps the brain to create new neural pathways.
70
But while the brain can form new connections,
71
neuroplasticity does not restore it to its original state or functionality.
72
Illness or injury has the potential to alter the brain,
73
sometimes for a while, other times forever.
74
After the accident, Phineas Gage lived another 12 years.
75
He died from multiple seizures undoubtedly linked to his brain damage.
76
He could never have imagined the legacy he left behind,
77
that his terrible accident would not only alter the course of his life,
78
but would forever change our understanding of the brain.

이 수업에 대하여

이번 수업에서는 뇌의 놀라운 회복력에 대한 이야기를 통해 영어 회화 실력을 향상시킬 것입니다. 비극적인 사고를 겪은 한 개인의 경험을 바탕으로 뇌의 신경 가소성과 개인적 변화를 살펴볼 것입니다. 이 과정을 통해 여러분은 단어와 표현을 학습하고, 영어 발음 교정에 도움을 받을 수 있습니다. 또한, 유튜브 영어 공부를 통해 흥미로운 내용을 접하며 실력을 쌓을 수 있는 기회를 제공받게 됩니다.

핵심 어휘 및 구문

  • 과거형 사고 - traumatic brain injury
  • 신경 가소성 - neuroplasticity
  • 프론탈 로브 - frontal lobe
  • 재훈련하다 - retrain
  • 인지적 노력 - cognitive effort
  • 반복 활동 - repetitive activity
  • 정신적 변화 - personality change
  • 주요 경로 - mountainous route

연습 팁

비디오의 속도와 톤에 맞춰 shadowspeak 기법을 사용하여 따라 말하는 연습을 추천합니다. Phineas Gage의 이야기는 복잡한 감정을 전달하므로, 여러분은 저자의 어조와 감성을 잘 살리도록 노력해야 합니다. 처음에는 천천히 따라 읽고, 자신의 발음을 녹음해 듣는 것이 좋습니다. 이 과정을 통해 자연스러운 영어 발음을 익히고, 정교한 문장 구조를 이해할 수 있습니다. 영어 회화 연습을 통해 자주 쓰이는 표현을 체화하고, IELTS 스피킹에서 요구하는 유창성을 높이십시오. 단어와 표현의 반복적인 연습은 뇌의 발달을 도울 뿐만 아니라, 대화 상황에서의 자신감도 키워줄 것입니다.

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.
