Could your brain repair itself? - Ralitsa Petrova

Imagine the brain could reboot, updating its damaged cells with new, improved units. That may sound like science fiction — but it’s a potential reality scientists are investigating right now. Ralitsa Petrova details the science behind neurogenesis and explains how we might harness it to reverse diseases like Alzheimer’s and Parkinson’s.

I would have to say the brain can repair itself, although some parts repair faster than others. Our son was in a car wreck over 17 years ago, when he was 18, and had the temporal and frontal lobes damaged. He had started college at sixteen years old. He had to learn to walk, talk and feed himself again. He has also overcome major memory issues. The last CT scan they ran on him showed new blood vessels had formed to bypass the damaged part of his brain. He was able to go back and finish college, and even completed grad school. He is our walking miracle.

If only humanity invested more funds and energy into researching such essential discoveries, instead of wars and lies, we could be living much happier lives.
My dad suffered from a very strong stroke and has recovered to some degree via lots of therapy, but he is still crippled. Imagine if we had a solution to his condition and to millions of others with similar conditions, how much happier this world could be!

My beloved mother just died of stroke three weeks ago! How I miss her so badly & wished this treatment was available to save her life. She was very active & had the sharpest brain! I wonder why she got such a massive stroke from nowhere!!! A grieving daughter 💔 wishes all people with debilitating diseases to heal!

This is weird. My brain is learning about my brain...

My answer to this question is: YES!

9 years ago I had an accident in which I fell on my head and fell into a coma of 2 months. After waking up out of coma, I heard the doctors telling my dad I'd never be able to talk nor to walk and exactly that drove me to work on myself to be able to do this things. I tried every day to walk even though the nurses told me not to, or I'd hurt myself. After 2 weeks I could walk again and after 3 weeks my first words were "Happy birthday mom". So never lose the beliefs and never lose the will to work on yourself, even if it my take decades.
My point is; IF the brain believes in itself, it can achieve wonders, as long as it never loses the believes in itself!!

Could your brain repair itself?
YES IT CAN!

I will tell you how it works, I had a stroke when i was 12, its called exercise. I couldnt talk or walk. So i grunted and grunted all day until i could finally say "ma" then so on, I eventually moved a finger and moved it all day until my whole hand, now i have my whole body, im fine

Even if you could regenerate the neurons, it is their synaptic networks that enable their efficient and repeatable functioning. In other words, despite having new cells to replace the damaged ones, patients would have to "re-learn" the information that the previous neurons contained by re-establishing that synaptic web

these researchers and doctors and scientists are our true heroes

One of the reasons that makes me happy to be alive in this age.

Love the illustration style and digging the knowledge!

My brain is completely recovered. Just before Covid lockdown, I suffered an unexpected blackout because I had hit my head. My brain was bleeding. While unconscious, I crashed into another car. I woke up in the hospital after a Crainiotomy.
I was well within a year. A HUGE challenge. You can get through this.

Last Year I lost my father to Parkinson's. I am glad we are slowly getting there I would love to contribute anything possible to see it a reality because I know what these things do to a family with a member suffering from it.

I love artistic expression of this one!!

The human brain is the most sophisticated computer ever, neuroplasticity is a wonderful thing

[jairoblas]

Has there been a follow up video? Of when can I find more about what was explained? Thanks!

[zappandy]

Pretty cool! Definitely want to read more about this. Can you imagine the implications of this discovery for learning processes? Awesome video as usual Ted guys.

[mayanlogos]

Great one... thank you for educating us! Information is power ❤

[troyhagen]

WOW THAT'S AWESOME BLOWN AWAY. INFORMATION AND VIDEO ARE AWESOME.

A brain can fix everything else in the world but can't fix itself

[marcellocapone]

Those cartoons are awesome! Great animating skills!
