1
The brain can not only stay healthy throughout your entire life, but also continue to improve.
2
He is Dr. Sanjay Gupta, American neurosurgeon and the chief medical correspondent for CNN.
3
And there's now a way that we realize and appreciate that within our skulls is an entire universe.
4
As our imaging grew more sophisticated, we started to see what the healthy brain really does look like.
5
and it's we talk a lot about the health of our bodies
6
but not as much about our brains
7
and i think for a lot of people there's this belief
8
that the brain is something that's not capable of really being optimized
9
or maintained i've been a neurosurgeon for some 25 years now
10
and i think a lot of people think about the brain
11
sort of as a black box you measure a black box by its inputs and its outputs,
12
but you don't really get to see the inner workings of the brain.
13
And I think that's why people have thought for a long time that it's immutable.
14
It's incapable of being changed in some way.
15
The brain is static and it's fixed.
16
And one of the things I really wanted to convey to all of you today is that that's not the case.
17
Perhaps more than any other organ in the body, the brain can not only stay healthy throughout your entire life,
18
but also continue to improve.
19
Over the last quarter century, we learned something that was pretty revelatory in the world of neuroscience.
20
We learned that you could continue to grow new brain cells at any age.
21
The conventional wisdom, even what I learned when I was studying neuroscience a quarter century ago,
22
was you got a certain number of neurons and that was basically what you got.
23
You drained the cash over the years of your life.
24
But that's not the case.
25
We believe that in part because the only time we really inspected the black box was when there was a problem, when there was a tumor or trauma.
26
We did not get to see the brain in sort of its healthy state.
27
We did not get to understand how the brain behaved most of the time.
28
As our imaging grew more sophisticated, we started to see what the healthy brain really does look like.
29
And it's stunning.
30
Inside your skulls right now, your brain is pulsing.
31
It's robust.
32
It's changing.
33
And it's growing.
34
And there's now a way that we realize and appreciate that within our skulls is an entire universe.
35
There are more neurons in your brain than there are stars in the sky.
36
I spent a lot of time talking to scientists who worked on this research and I asked them, how do they fundamentally live their lives now differently because of what they've learned?
37
And the way
38
that I sort of broke this down is into the big buckets of how we live our lives through movement,
39
through nourishment, through rest, through connection, and through discovery.
40
I think movement is the most reliable way to grow new brain cells.
41
The more you move, the more you are sending signals essentially to your entire body that you want to be here, that you want to be healthy.
42
But most remarkably, you're sending a signal for the brain to create a substance known as BDNF, brain-derived neurotrophic factor.
43
You don't need to remember that, but think of that as sort of the miracle grow for the brain, as one scientist put it to me.
44
It's the substance that is actually promoting that neurogenesis, telling new brain cells to grow.
45
You cannot ingest it.
46
You cannot eat it.
47
It can only be made by your own body.
48
The brain is very sensitive to glucose.
49
So as your blood glucose starts to really rise, the receptors in the brain, instead of absorbing all that energy, they turn off.
50
They simply stop absorbing any energy.
51
So at the same time, you're eating a really, really calorie-dense meal full of a lot of sugar.
52
You could be overstuffing your body and starving your brain at the same time.
53
That's a difference between the brain and the rest of the body.
54
Hydration, critically important for all functions hydration is one of the substrates that is necessary for BDNF,
55
but one needs to keep in mind that the brain itself is 85% water.
56
What that means is just 1% dehydration can lead to a 5% decrease in cognitive function.
57
1%.
58
I mean, I think this is one of the most under-recognized things that we talk about with regard to cognition overall.
59
A 2% decrease in hydration can result in acute short-term memory loss, objective problems with mathematical computations,
60
and an inability to store long-term memories.
61
Just 2%.
62
So sugar and water, so critical when it comes to brain health for those reasons.
63
Sleep, rest, again, we know is important.
64
But for the brain, sleep is not a period of inactivity.
65
In fact, it's one of the most metabolically active times for the brain.
66
And we know that your brain is constantly creating waste products and those waste products are constantly being cleared,
67
but it is during sleep when that waste clearance is most efficient.
68
Sleep is really important for clearing away some of the substrates that may be the precursors to things like amyloid plaque,
69
which is associated with Alzheimer's disease.
70
We also know that sleep is when you actually take your short-term memories
71
and you actually put them into a long-term memory store.

Für wen ist dieses Video geeignet?

Dieses Video eignet sich perfekt für Lerner, die bereits ein grundlegendes Englisch beherrschen und ihre Sprachfertigkeiten vertiefen wollen. Es hilft, komplexe Themen zu verstehen und gesprochene Englisch in natürlicher Umgebung zu üben – ideal für diejenigen, die "Englisch sprechen üben" wollen, ohne sich auf einfache Sätze zu beschränken. Ob du an wissenschaftlichen Texten interessiert bist oder einfach nur dein Hörverstehen und Reden verbessern willst, hier findest du eine reiche Quelle an Inhalten.

Wörter und Redewendungen, die sich lohnen zu lernen

  • Immutable: Unveränderlich. "The brain is not immutable" – Das Gehirn ist nicht unveränderlich.
  • Neurogenesis: Die Entstehung neuer Nervenzellen. "Promoting neurogenesis" – Die Entstehung neuer Nervenzellen fördern.
  • Miracle grow: Einidiom für etwas, das wunderbar wachsen lässt. "Think of it as miracle grow" – Stelle dir vor, es ist wie ein Wunderwachstumsstoff.
  • Black box: Ein System, dessen Innenleben unklar ist. "The brain as a black box" – Das Gehirn als eine Schwarze Kiste.

Wie man den Akzent richtig hört und spricht

Der Sprecher, Dr. Sanjay Gupta, hat einen klaren, verständlichen Akzent mit natürlicher Intonation. Achte darauf, wie er lange Sätze pausiert – nicht zu schnell, sondern mit Rhythmus. Um dein "shadow speak" zu verbessern, wiederhole seine Sätze direkt nach ihm, achte auf die Betonung von Wörtern wie "neurosurgeon" oder "neurotrophic". Übe "shadow speech", indem du die Pausen nachahmens: Wenn er sagt "the brain can not only stay healthy... but also continue to improve", mach eine kurze Pause vor "but also". Das hilft, die natürliche Fluss zu lernen. Für "Englisch sprechen üben" ist es wichtig, die Betonung auf Schlüsselwörter zu legen, wie "robust" oder "stunning". Probier es aus: Nimm einen Satz, wie "inside your skulls right now, your brain is pulsing", und wiederhole ihn mit demselben Tempo. "Shadowspeak" macht Spaß – und es verbessert deinen Akzent unmerklich!

Mit solchen Übungen wirst du nicht nur die Sprache, sondern auch das Verständnis komplexer Themen verbessern. Also: Mach los, und übe "shadow speak" – dein Gehirn wird es danken!

Was ist die Shadowing-Technik?

Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.
