How Close Are We to Downloading the Human Brain?


Someday our bodies are going to break down
and we’ll die. Our brain will decay and disappear forever.But,
what if it didn’t have to? Right now there are scientists around the
world working on technology that could one day take your brain, and possibly your consciousness,
and upload it onto a computer. This would be a game changer in neuroscience
and some believe could lead to immortality. So, how close are we to downloading our brains? Okay first off, what do we mean when we say
“downloading the brain?” It’s not plugging a cable into your head
and syncing it with your phone. It is much more complicated than that because,
well, the brain is really, really complicated. The information in a brain is encoded in the
synaptic connections between neurons. This is the major theory of how not only episodic
memories are encoded in the brain, but essentially all learned knowledge, // Now, there’s on
the order of 100 billion neurons in a human brain and each of those neurons has tens of
thousands of connections. You are looking at hundreds of trillions of
those synaptic connections, each of which have been tuned by your life’s experience. So in order to download your brain, each one
of those trillions of connections would have to be precisely scanned, mapped and digitally
reconstructed on a computer as an emulated brain. The idea would be, that this simulation would
not only behave like a biological brain, but could retain the thoughts and memories of
the person whose brain was scanned. Now, all this is great to think about and
makes for interesting dinner conversation, but we have yet to scan a complete human brain
let alone test the theory of consciousness. That’s not to say some progress hasn’t
been made though. There are projects all over the world working
on scanning and simulating brains in the name of healthcare and medicine. This is more about unlocking mysteries of
our brain and less about unlocking the key to immortality. …we don’t really understand a system until
we can build it ourselves and manipulate it in a computer, and really understand all the
pieces and parts. In 2014, researchers scanned a roundworm brain
and made a simulation that they installed into a simple Lego robot. And, the simulated brain moved the robot freely
without any human direction. There have been other projects trying to recreate
the brain through reverse engineering, experiments reading and implanting memories and one group
created an algorithm for large scale human brain simulations. But one of the biggest projects involving
actual brain scanning is taking place at the Allen Institute in Seattle. They have scanned and digitally reconstructed
a cubic millimeter of a mouse brain. Yes, this may not seem like a big deal due
to the small scale, but this is the largest roadmap of connections of a mammalian brain
ever. Now, a cubic millimeter is about the size
of a single grain of sand and is home to 100,000 neurons and over a billion synapses. In order to scan this tiny segment, it first
had to be sectioned 25,000 with each slice being about a fifth the thickness of a human hair.
were taken. Then 10s of millions of images were taken. This gives you an idea of what would need to happen to scan an entire human
brain. That means that mapping a human brain, a million
times larger, would take a fleet of electron microscopes decades in order to image. Obviously the technology is going to have
to change. Perhaps not radically but at least in scale
to make something like this happen. We just don’t have powerful enough microscopes
to be able to accurately and efficiently image entire human brain. And even if we could, the question would still
remain; if we could copy our brain, would that also copy our consciousness? Most neuroscientists would say yes, it’s exactly
the same person if it’s exactly the same thing, but we really don’t know if there’s some other
issue that we’re missing. // Still the question is, is the simulation
at a resolution that is sufficient to capture who you are? The idea is that our thoughts and memories
are basically data, and in theory we should be able to copy that data over to a computer
and you’d still be you. But, what kind of you? …if we made a replication of your brain,
there’s no reason that you’d be living in silence and darkness inside Dropbox. We’d be giving you fake input. In theory, if somebody were a computer simulation
// what it would be like is exactly what this is like for us. You’d look around, you’d say, “Here I am,
I can feel my body, I can taste this drink, I can eat this pizza,” and it in theory wouldn’t
be any different. Or if you want to still experience the real
world, your brain could be installed into a robot. The person opens up their robotic eyes, and
they say, “Wow, I’m still here.” If it works, that’s how it should feel. It should feel like you are coming out of
a surgery and you should be able to call up memories from your past, you should be able
to still remember how to do certain things, you should have the same likes and dislikes… However, advancements in connectomics won’t
come from scientists looking for the fountain of youth. Researchers want to understand the brain better
in order to combat disease and mental disorders. We’d be able to better treat tumors, epilepsy,
addiction and learn more about how we evolved. This is why people are looking to digitally
map the brain. In the end, if we are ever able to upload
someone’s consciousness, it may just be a bonus to these studies. Mind uploading is a very long-term project
of humanity. It’s so long-term that I think most of the
people today that are working on it would not recognize that they’re working on it. The desire is there to scan and map an
entire human brain. That process may lay the groundwork for a
brave volunteer to have their brain removed and digitized which might lead to the first
immortal being. We just have to wait for technology to catch
up with our ambition. So, how close are we to downloading the human
brain? We’re nowhere close. We can’t even download a fruit fly…. We can image small pieces of brain tissue,
or small organisms brains. But, we don’t know enough about how the nervous
system works in order to interpret those images and create a simulation of that. With the technology the we have right now,
we’re nowhere close. But the road seems clear enough to get there,
unless there’s some giant surprise that we run into. It seems like each year as technology gets
better and better, we get higher and higher resolution on what’s going on. It’s a clear path to get there. I mean, unless we already are there and you
are currently watching this in a computer simulated world where nothing around you really
exists. Thanks for watching How Close Are We! Let us know in the comments what topics you want us to cover in future episodes. And if you want more How Close Are We, click here to watch our playlist. And don’t forget to like, share, and subscribe.

  1. But even if your brain is scanned it’s still not you because your not transferring yourself. It’s just a digitalised version of yourself

  2. Yeah ok. Live forever, cool. But what about the fact that this would be a COPY? When you copy a CD to your computer, the fragile disc that has the original information still exists separately from your computer. If you ever uploaded your brain along with a COPY of your consciousness, your brain is still separate from that copy. You are still in reality and you are going to die. That copy is not you, no matter how much it thinks it is

  3. The video doesn't address continuity of existence, the process shouldn't be copying, is should be displacing that consciousness

  4. It's not a transfer, it's a clone. It's misleading to suggest it'll make us immortal, since a digital version of my brain is a separate entity to me (since we can live simultaneously), even if we're identical. So it's kind of pointless.

  5. Something tells me this would be easier to achieve using a quantum computer of some type, but that technology is still being worked on like this is.

  6. Please don’t download from my brain 🧠
    Inside are porn site and toxic idiot behaviour
    Im a Billy last time hope I want new Brain that clear and become a wealthy in future 😂🤣 😜

  7. Are you totally crazy? When the last life cycle is over, the soul releases itself from the body and is free again.
    The thought that this is actually being philosophized about it The awareness of imprisoning the energy or the soul in a technology is really more than frightening and very very ignorant!

  8. everything is digitalized, there is no point of "human". every knowledge/memory will be merged into one central computer. lol

  9. Doesnt God Offer Us Eternal Salvation If We Believe And Worship? Do the right thing etc…if only the scientists would believe in God, Soul And Afterlife. They Truely Can Earn Immortality In The Kingdom Of Heaven Where Evil And Nagging Wifes Don't Exist.

  10. To copy the consciousness accurately. We need to understand all forms of electro-magnetism as well as electricity of brain waves in connection to the body( may be a more proper term).

  11. Err, sorry to bother you guys with this question.
    Technically, if your brain gets sliced you die.
    Now, let's admit the digital copy works perfectly and gets uploaded on a platform, a robot. 
    It wouldn't be "you", it would be a copy of your brain on a different platform, some sort of "clone".
    But you died, you never wake up from the surgery, someone else does, with the same brain you had.

  12. Yeah well most will not be able to afford it

    The elite will simply make slave robots without a way to think other than clean this

    Go get that so don't get your hopes up no matter what

    Have a nice day we're doomed

  13. 1 of the issues I perceive is the mathematical equivalent of the information contained within is there but the experience of the moment probably wouldn't transfer over .

  14. It always fascinates me how much trouble these bright PhDs have grasping the Law of Accelerating Returns and fundamentally understand exponentiality. Reading Kurzweil should be mandatory in STEM fields…

  15. It's true nothing around us actually exists…. even ourselves are merely a simulation to keep ourselves busy the singular being that has always been.

  16. I feel like we can only live forever by removing our brain and put it on top of a computer of some sort. If we just downloaded our brain it would just be a copy, you cant copy conciousness, its only in your brain.

  17. Who knows, maybe some day mankind will be able to copy itself to a computer but i highly dought that we will ever be able to copy the consciousness to a computer.

  18. Saying you can make a conciousness by building a neuro roadmap is like saying taking a picture of a person is the same as cloning

  19. the brain has electrons and energy I wonder would it b possible to install a chip with say wires to collect data with tb full of space to receive the data something to think about and makes a great conversation

  20. I believe our ability to understand what we see will hit a wall. Kind of like a dog can See a car but doesn't understand how it works.
    Especially when confronted with the universe we see this in quantum mechanics.

  21. The interesting question is….can it be encrypted. Sole owner no peak.🤫🧖🏾‍♂️🙏🏿💯😂😎

  22. WHY GIVE UP MY BODY AND FREE WILL ON A DECEPTIVE LIE OR THEORY OR EDUCATED GUESS?… ALSO WHO OR WHAT WILL BE IN REPLACEMENT IN MY PHYSICAL BODY? THE CREATOR GIVEN ME THIS PERFECT GIFT, WITH ALL I NEED. NO THANKS YOU SCIENCE. . I'M GOOD.🤗👍💯. TO EACH HIS/HER OWN. HIS GRACE AND MERCY SUFFICIENT 🕊️🙌 💖😇💯

  23. if they can copy our memory from brain, but can they copy and reproduce same emotion after it copied? i interested but not really want it.

  24. Your brain is a processor that connects your body to your soul. There is no "conscience" that you can upload or download to a computer. You might be able to stimulate or replicate someone, but it won't be "them" in reality, just a digital version.

  25. That's a big 'possibly' on the consciousness part. We still have no clue what it is or where it's 'produced', so emulating it sounds a bit far-fetched. Don't get me wrong, it's a great endeavor but that's a heavy reliance on the assumption of the materialistic human model.

  26. I just hope someone, someday will be able to create a robotic body capable of keeping a human brain alive for essential forever.

  27. For all of those worried. Have an analogy to try and make you feel better:
    Taking all the info of the brain and moving it to another body is like taking out all the insides of your computer and putting it in a different compartment. Theoretically, it should all be the same and all the data should still be there. It just looks different.

  28. i'm more interested in combining this tech with time travel tech, first i'm traveling to my grader self, then i'm gonna convince my younger self, that, with the gift of (a 40-year) foresight, my memories can make his life a whole lot better with a lot less fewer mistakes and embarrassments growing up, not to mention be able to skip endless hours of studying and easily ace exams (having multiple post-graduate courses, yeah that will help a lot), knowing how to behave around and win over, one after another, the hot girls who should have dumped me (for a while back i studied pick up artist techniques, and every once in a while it does come in handy; imagine a 10yo in the 90's knowing how to pass "shit tests" before touching high school), start my self-improvement program since childhood (i learned 2 decades late that a certain local store selling height and muscle enhancements already existed since my childhood), and (most importantly) be able to know how to methodically plan my life, contact the right people a decade before i should have known them, sell properties to their historical buyers just a few months earlier than they should have been bought (and beat their historical middlemen of a few commissions), and snipe all of the business deals that should have been a life-changer for me. and financially retire before my age now. at the rate i'm going now i might just retire within 15yrs, imagine the inefficiency of lack of remembering the future. in an efficient alternate present, i'm a backpacker with my family traveling the world.

    in essence, if i download older me into younger me, i'll be able to approximate eddie morra, and be the closest thing to being the real life eddie morra, because i'll be taking advantage of an entire lifetime's worth of thinking the best strategy for having a great life. locally, that would mean i'll be able to create a whole lot more jobs that much sooner, and get wealthier that much sooner (for those not in the know, wealth is the confidence and the skill to efficiently acquire money, being rich is merely holding an amount; ignorant people refer all the time to wealthy people as rich people, explaining why they themselves are not: they are primitive in this area, when they should have been sophisticated, they should not rely on hard work of just 2 hands, they should work at 25% effort based on smart work, because they create systems [entrepreneurships], and/or get involved in other systems (stock market, franchises, etc.), and let all those systems work for them, robert kiyosaki call these "financial vehicles").

  29. Missing a piece? No, he said it. Its a copy. Even if its a perfect copy, its just a copy. The only way to do it correctly is two-fold. You create nanobots that explore the brain's pathways and make a copy of the data in a computer. Those nano-bots then carefully begin converting the inorganic material slowly into new material like silicon or whatever is better at relaying the electrical activity in the brain. Done. Simple, and actually easier than they are saying it is.

    Slow conversion also allows new memories along with old ones to still be added, and when a brain cell dies, the nano-bots can restore or replace them. The method of scanning is the problem. it uses the old method of "Cat Scans" in a huge over priced magnetized doughnut. You need a swarm of these nano-bots doing the work so there isn't all this hack and slash crap going on and the scans are internal rather than external. Furthermore, we can create them now.

    People involved are simply milking it and delaying the developments. If we lit a fire under their asses you can bet it would already have been accomplished as early as the 90's. its long over due to push them to get it moving already and stop the dragging of the feet and wasting time on philosophy and nonsense. Nano-bots BTW are insanely cheap. https://www.nanowerk.com/nanotechnology-news/newsid=48780.php. and something more current; https://www.youtube.com/watch?v=h6U4s5n2P5o.

  30. Idk ..how good would being able to maintain consciousness be? Being able to see everything deteriorated around you. Watch the cockroaches take over.

  31. I've dreamed about this since i was 7 yrs old, we will not die so easy at all and if we stay safe we will not die at all, we can update our bodies with time passing and stop the feeling of pain.

  32. One way that may work making the brain is to build physical electronic neurons that can work similarly to virtual artificial neurons. But these will work differently than normal digital circuits. Next you connect it to the brain and new memories will be stored into it but it will not be sure what would happen after it is disconnected

  33. Maybe the mass is type of data that exists, i think that's why sometimes in some chemical reaction the mass gets more then it should be

  34. The brain and mind are two different things

    The sensory world, the holos, is a kind of mathematical simulation, a shared dream space, all of which is a Fourier mental projection from the mathematical source singularity. You aren’t a body, you’re an eternal mind, which is a complete set of Fourier basis waves. Your body is simply an avatar that your mind links to in order to directly interact in the spacetime holos. As a mind, you’re eternal and can never die.
    I'm hoping the mind is like a finger print
    All one has to do hypothetically
    Is transfer the mind to a new brain like a antenna
    A crystal or wireless receiver
    Something like that
    I don't know
    But thats where I'd search
    Quantum
    It would hurt to explore the possibilities
    I hope
    Then we can reverse engineer
    So Sophia the Robot can have a organic body
    We can have multiple bodies and brains but 1 fractal mind among many others in the singularity expiration
    Within singularity expansions
    Many fractals and psychosocial
    plausible hypothesis
    With some theory
    Thats what I would do
    Crapitalism is to limiting

  35. I don't like to use the universe is a video game analysis
    Because its more robust then that
    Hypothesis
    We are wring the universe code
    Or 🤔 allowed to write within this quantum
    We design things
    Convert quantum matter into different shapes
    Process
    Order of oppressions
    Mathematics
    A computer within a computer in essence
    We are the universe experiencing itself
    Technically
    We can create universe or heavens
    Crapitalism is to limiting
    No disrespect to all religious people
    The bible is to limiting
    Some of the philosophy from the bible is useful
    But my religion is different

    Ephemeralization
    Ephemeralization, a term coined by R. Buckminster Fuller, is the ability of technological advancement to do "more and more with less and less until eventually you can do everything with nothing," that is, an accelerating increase in the efficiency of achieving the same or more output while requiring less input. Fuller's vision was that ephemeralization will result in ever-increasing standards of living for an ever-growing population despite finite resources. The concept has been embraced by those who argue against Malthusian philosophy.

    I don't need a bible to understand good and evil
    I need to understand light and dark energy
    And what leads people to do bad things
    Thats value of understanding or knowledge
    And define bad
    Love is priceless regardless of
    Sex, gender, race or country
    You can't love freedom and the bible
    The bible supports slavery
    Is it ok to own slaves
    If so them be mine 👍
    I know we can't have absolute freedom to do whatever
    But im just saying
    We must find balance
    I'm not anti God
    Im pro Gods
    As in we become Gods
    As in co creation
    No to abuse power
    Merit is important
    Thats why we have impeachment process
    Regardless of trump of whoever
    But it's needs to be understood
    We must learn our true purpose for existence
    And it isn't to make money
    A deeper elevation

    "the kiss dematerializes into a kind of spiritual rebirth"

  37. ontological mathematics
    the mathematical waveforms of mind that make up all of existence and yourself.
    You aren’t a body, you’re an eternal mind
    Thoughts are mathematical sinusoidal waves.
    Your body is simply an avatar that your mind links to in order to directly interact in the spacetime holos 🕵️‍♀️ Give her allot of credit she deserves it 👍
    taught by Hyperian Revenant Christina Awakened, assumes no mathematical background except for basic algebra.
    This is not a reality of matter, rather, it’s a reality mind,
    The only thing I disagree with is the matter aspect
    The perception of matter is wrong
    But matter exists
    Just not our perception of what it is
    It's all quantum
    And it's shapable and interactive
    It's so we can interact with the quantum
    Our avatars

  38. there is no way of knowing if you would still be "you" because the robot may say it is you but it is a copy of you that has the memory of it going through this process, but it wont be "you"

  39. Well then the philosophy of brain vs soul comes into play. This technology can duplicate your consciousness but is it actually “you”. Imagine doing it while you’re alive and talking to your clone basically. When you die, it’s not like you’ll wake up in that “computer” but a clone of your consciousness will go on. That’s why in movies like the matrix, if you died there you died in the real world too.

  40. I was thinking the same thing in my mind how we can live forever …. so this idea is taken , so i have to find diffrent idea… stay creative 🍎( when we shutdown your brain its feel you r in dreams… if you copy your brain and run it using AI then you will feel like waking up in morning in diffrent body …..)

  41. Mock my words people. I'll make this happen, or I'll die trying. Living forever via uploading your consciousness will be a new level for us. We'll finally beat the one enemy humans have always had. Death.
    Don't ask me how ill do or when. But I'll do it.
