The brain can not only stay healthy throughout your entire life, but also continue to improve.

He is Dr. Sanjay Gupta, American neurosurgeon and the chief medical correspondent for CNN.

And there's now a way that we realize and appreciate that within our skulls is an entire universe.

As our imaging grew more sophisticated, we started to see what the healthy brain really does look like.

and it's we talk a lot about the health of our bodies

but not as much about our brains

and i think for a lot of people there's this belief

that the brain is something that's not capable of really being optimized

or maintained i've been a neurosurgeon for some 25 years now

and i think a lot of people think about the brain

sort of as a black box you measure a black box by its inputs and its outputs,

but you don't really get to see the inner workings of the brain.

And I think that's why people have thought for a long time that it's immutable.

It's incapable of being changed in some way.

The brain is static and it's fixed.

And one of the things I really wanted to convey to all of you today is that that's not the case.

Perhaps more than any other organ in the body, the brain can not only stay healthy throughout your entire life,

but also continue to improve.

Over the last quarter century, we learned something that was pretty revelatory in the world of neuroscience.

We learned that you could continue to grow new brain cells at any age.

The conventional wisdom, even what I learned when I was studying neuroscience a quarter century ago,

was you got a certain number of neurons and that was basically what you got.

You drained the cash over the years of your life.

But that's not the case.

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.

We did not get to see the brain in sort of its healthy state.

We did not get to understand how the brain behaved most of the time.

As our imaging grew more sophisticated, we started to see what the healthy brain really does look like.

And it's stunning.

Inside your skulls right now, your brain is pulsing.

It's robust.

It's changing.

And it's growing.

And there's now a way that we realize and appreciate that within our skulls is an entire universe.

There are more neurons in your brain than there are stars in the sky.

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?

And the way

that I sort of broke this down is into the big buckets of how we live our lives through movement,

through nourishment, through rest, through connection, and through discovery.

I think movement is the most reliable way to grow new brain cells.

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.

But most remarkably, you're sending a signal for the brain to create a substance known as BDNF, brain-derived neurotrophic factor.

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.

It's the substance that is actually promoting that neurogenesis, telling new brain cells to grow.

You cannot ingest it.

You cannot eat it.

It can only be made by your own body.

The brain is very sensitive to glucose.

So as your blood glucose starts to really rise, the receptors in the brain, instead of absorbing all that energy, they turn off.

They simply stop absorbing any energy.

So at the same time, you're eating a really, really calorie-dense meal full of a lot of sugar.

You could be overstuffing your body and starving your brain at the same time.

That's a difference between the brain and the rest of the body.

Hydration, critically important for all functions hydration is one of the substrates that is necessary for BDNF,

but one needs to keep in mind that the brain itself is 85% water.

What that means is just 1% dehydration can lead to a 5% decrease in cognitive function.

1%.

I mean, I think this is one of the most under-recognized things that we talk about with regard to cognition overall.

A 2% decrease in hydration can result in acute short-term memory loss, objective problems with mathematical computations,

and an inability to store long-term memories.

Just 2%.

So sugar and water, so critical when it comes to brain health for those reasons.

Sleep, rest, again, we know is important.

But for the brain, sleep is not a period of inactivity.

In fact, it's one of the most metabolically active times for the brain.

And we know that your brain is constantly creating waste products and those waste products are constantly being cleared,

but it is during sleep when that waste clearance is most efficient.

Sleep is really important for clearing away some of the substrates that may be the precursors to things like amyloid plaque,

which is associated with Alzheimer's disease.

We also know that sleep is when you actually take your short-term memories

and you actually put them into a long-term memory store.

FOR YOU

Цели говорения для этого клипа

Этот видеоклип помогает улучшить свободное выражение сложных идей на английском, а также научиться структурировать речь логически. Цель — достичь уверенности в разговорах на темы здоровья и науки, что является важным этапом развития устной речи. Также упражнения на основе этого материала совершенствуют навык shadowing английский — воспроизведения речи после носителя языка, что критически важно для улучшения произношения и ритма.

Банк фраз

"continue to improve" — продолжать улучшаться
"conventional wisdom" — общепринятые представления
"neurogenesis" — нейрогенез (рождение новых нейронов)
"miracle grow for the brain" — чудодейственное удобрение для мозга
"receptors in the brain" — рецепторы в мозге

Эти фразы можно использовать в научных дискуссиях, разговорах о здоровье или презентациях, что делает их универсальными для разных контекстов.

Исправляем слабые места

Основная проблема, с которой помогает справиться этот материал — улучшение произношения английского за счет работы с ритмом и интонацией. Речь доктора Гупты имеет естественный темп, с ясными паузами и акцентами, что идеально подходит для shadow speech (воспроизведения речи после записи). Чтобы добиться результата, используйте метод shadowing: слушайте короткий отрезок, затем повторяйте его сразу, копируя интонацию и темп. Для тренировки можно использовать специальные shadowing site, где вы найдете записи с разными темпами. Важно обращать внимание на звуки "th" (в слове "the") и правильное ударение в сложных словах, например "neurosurgeon". Регулярная практика shadowspeak поможет сделать речь более естественной и понятной для носителей языка.

Конструкции, которые говорящий использует чаще всего, с точными словами из видео:

Конструкция	В видео
Пассивный залог be + причастие прошедшего времени — важно, что происходит, а не кто это делает	being optimized · being changed · be made
Present Perfect have/has + причастие прошедшего времени — прошлое действие, важное сейчас	i've been · have thought · they've learned

Что такое техника Shadowing?

Shadowing — это научно обоснованная техника изучения языка, изначально разработанная для подготовки профессиональных переводчиков и популяризированная полиглотом доктором Александром Аргуэльесом. Метод прост, но эффективен: вы слушаете аудио на английском от носителей языка и немедленно повторяете вслух — как тень, следующая за говорящим с задержкой в 1–2 секунды. В отличие от пассивного прослушивания или грамматических упражнений, Shadowing заставляет мозг и мышцы рта одновременно обрабатывать и воспроизводить реальные речевые паттерны. Исследования показывают, что это значительно улучшает точность произношения, интонацию, ритм, связную речь, понимание на слух и беглость речи — что делает его одним из самых эффективных методов для подготовки к IELTS Speaking и реального общения на английском.
