This is such a fascinating topic that really dives into the complex intersection of science and our future as a species. As a therapist and combat veteran, I’ve seen how technology can both help and hurt mental health, and this concept of uploading consciousness raises so many important questions. It's incredible to think about the possibility of transcending our biological limitations, but we also have to consider the ethical implications and potential risks. I’ve been creating content on my channel, Empowerment Psychology, to help people navigate challenges like trauma, PTSD, and more, and if you’re interested in these kinds of deep discussions, feel free to check it out. Thank you for shedding light on this mind-bending subject!

An amazing video depicting the mysteries of human brain. So good, so informative. Special thanks to the researchers, narrators, writers and graphics producers for making this video so attractive.

Marijuana smoke is not as damaging as cigarette smoke because it has no nicotine, which is very nasty. Nicotine knocks out the inhibitor of elastase, freeing the enzyme to eat elastin, which is a major component of lung tissue. Nicotine also defuses through the body, so it is able to destroy elastin in the skin - leading to smokers bad skin. Probably the most insidious effect of nicotine is that it mimics a signal that causes cells to release from the basement membrane, which is why smokers have more metastasis in every kind of cancer, not just lung cancer. Hot particles and tar are bad for the lungs, so smoking pot is bad too, but epidemiological studies show a dramatic difference in outcomes.

Creating a digital copy of your brain involves the concept of "mind uploading, " where the goal is to replicate the structure and functions of the human brain in a digital format. This would require detailed mapping of neural connections and processes, as well as the development of sophisticated algorithms to simulate brain activity. While still largely theoretical, advances in neuroscience and computing continue to explore the feasibility of this idea. Ethical, philosophical, and technical challenges remain significant, such as ensuring the accuracy of the digital model and addressing the implications for personal identity and consciousness.

Thank you very much for the informative documentary, BBC! Would you have the possibility to add references to the academic publications used for making the documentary in the video description. One more point: I think there was too much focus on the effect of drugs on the brain (which could have been moved to a separate documentary). At least for me, more interesting is the computational / cognitive aspects of the human brain. Another idea for such documentaries is to add partial interviews with leading neuroscientists. Thank you!

My friend had 1/2 a brian. She had some weird effects but over all you would not be able to tell anything was amiss. Her mother was exposed to the virus in cats feeces and it is believed to have caused this.

Very interesting and informative video. I do have one minor...uh....I guess call it a respectful but strong disagreement on one particular example that was given regarding differences between the male and female brain. It's said at 25:44 that women are better multitaskers. My thing is, multitasking doesn't really exist in the way people understand it. Our brains are only capable of focusing on one major task at a single moment while all the other tasks get put on hold so to speak. Our attention can be taken off one task for a brief time in order to do a different task. If we actually try to force our brains to fully focus on more than one task at a time, really weird and sometimes scary or tragic things can happen. Obviously there are certain things this can be done with. Like I personally can walk and chew gum at the same time. Silly example but it gets the point across. Now think about seeing a woman (I'm only using this particular example because I have seen it too many times with my own eyes) driving next to you on the freeway. You clearly see her talking away with no passenger. Ok duh, sure she's on he car Bluetooth. Ok she is also trying to get her lipstick or mascara or whatever on by glancing back and forth in the rearview mirror. So shes starting to drift between the lines of her lane but still able to stay within them so far. That is until her purse puppy jumps from the backseat on to her lap spilling the hot ass cappuccino she just embarrassingly over paid for all over her lap sending the mascara wand into her eye as she tries in a panic to stop her ass from being burnt with the coffee by shooting up in her seat causing the purse puppy to get wedged in to the steering wheel yoking it to a position that isn't going to be very pretty due to the fact that she is currently driving 65 mph on a freeway where there are COUNTLESS innocent bystanders.

Sure it's a bit of an extreme example but the same could be done for a normal situation at home.

My ultimate point is that while we are capable of performing certain functions without having to actually think about what we are doing (I don't mean breathing. More like feeding our pets or simple household chores. Things that are very straightforward from the beginning, but when it's been done each and every day or week for years and years. ) when we start adding tasks that are more complex in nature or that involve the safety and welfare of people or pets that's when things start to go wrong.

Seems more like being a master of time management. Almost like cooking a meal from scratch. Learning to start with what part takes the longest to cook and cooking the meal in a way that has everything getting done and served at the same time while still hot. Just replace the ingredients with miscellaneous tasks. Yeah that's not multitasking. That is AMAZINGLY SUPERIOR time management. Oh and yeah women are FAR better at time management than men....imho.

Solve tooth decay first then focus on mind upload.

El Cerebro es muy hermoso y necesita mucho cuidado una temperatura ideal provocaría que el cerebro se restaure .
Mantener a una persona en una habitación con una temperatura constante de 53 grados centigrados por 10 horas ayudará a mejorar su salud mental

Thanks for explaining the intricacies of functional structural and behavioral dynamics of brain default mode network.😊❤

Just reminded me of a series called Black mirror

The most important organ in the body 👍🏿

[allenwalker]

What I believe is that, the brain is an electronic device just like a smartphone, a computer name them😅 which is capable of recording information, storing it, retrieving it and can use some portions of that information to create videos you watch when you're asleep 😂 I mean the dreams. And this device is always charged for it's active 24hrs a day😅😅😅. I respect the assembler of the human body mechanism 😮

While using YouTube at home while on wifi, change your resolution to 144 to use less data on mobile devices.

Im pritty sure Lewis Carroll was on lsd when he wrote alice in wounderland and through the looking glass

This British Peter Parker makes some good points.

I fail to understand how this could possibly achieve the desired result of extending life past physical death. Even if one day it would be possible to upload our mind to digital form, that would still be a simulation, a copy of your mind, an approximation. It wouldn't be you.
