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.

Contexto & Antecedentes

No vídeo “A maneira incrível como nosso cérebro pode se curar | BBC Ideas”, somos apresentados ao caso inspirador de Phineas Gage, um trabalhador da construção civil americano que sobreviveu a um acidente traumático que afetou seu cérebro. O exemplo de Gage nos ensina sobre a resiliência do cérebro humano, mostrando como ele pode se adaptar e se recuperar após lesões. Essa história não só destaca a capacidade de neuroplasticidade, mas também fornece insights sobre como diferentes partes do cérebro estão conectadas às nossas funções comportamentais e emocionais.

As 5 Frases Principais para Comunicação Diária

  • "Ele não era mais ele mesmo."— Use essa frase para descrever mudanças em comportamento.
  • "O cérebro pode se adaptar."— Uma afirmação sobre a resiliência mental.
  • "Mudanças podem ser reversíveis."— Um ponto importante sobre a transformação pessoal.
  • "A recuperação é um processo."— Refere-se ao caminho que podemos tomar para nos recuperar de dificuldades.
  • "Tudo é uma questão de prática."— Ideal para motivar a perseverança, seja em habilidades de fala ou em outras áreas.

Guia Passo a Passo para Shadowing

Para aprimorar sua pronúncia em inglês usando técnicas de shadowing em inglês, siga este método eficaz inspirado no vídeo sobre Phineas Gage:

  1. Escolha um trecho do vídeo: Selecione uma parte que você ache interessante e que contenha frases úteis.
  2. Ouça ativamente: Pare e ouça a pronúncia e a entonação do falante. Preste atenção nas emoções transmitidas durante a narração.
  3. Reproduza as frases: Tente repetir as falas em voz alta imediatamente após ouvi-las. Isso é essencial para desenvolver sua habilidade de shadowspeak.
  4. Grave sua voz: Gravar sua própria repetição pode ajudá-lo a perceber a diferença entre sua pronúncia e a original.
  5. Pratique regularmente: A prática constante levará a uma melhoria significativa e ajudará você a dominar o shadow speech. Incorpore essas técnicas em sua rotina diária para benefício máximo.

Através deste vívido exemplo e técnicas de shadowing, você pode desenvolver uma compreensão mais profunda do inglês, melhorando não apenas sua fala, mas também sua autoconfiança ao se comunicar. Lembre-se: a melhoria na pronúncia em inglês é um resultado direto da prática e da dedicação!

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
