www.ted.com Henry Markram says the mysteries of the mind can be solved -- soon. Mental illness, memory, perception: they're made of neurons and electric signals, and he plans to find them with a supercomputer that models all the brain's 100,000,000,000,000 synapses.

Of course, I did need to search up a bit to have a more thorough understanding of what he was talking about, but hey, we never stop learning. In face, this video, along with Jill Bolte Taylor's TED talk enabled me to get a 96% on my English essay about truth, reality and perception! I love learning about the brain, and this project excites me!

@Udinbak cont. It could see which connections are active during a particular thought, it could refine it's thoguht processes, edvice on improvements, or refinements. It could ask to sever a synapse in order to reduce an unwanted response, strengthen it to increase a desireable response, even request a new synaptic pathway to connect and explore disparate functions/memories/senses/etc (synesthesia). If the new region could make these adjustments, then it would be able to do it automatically.

just a few tips to consider when you've got the brain mapped and symulated.. basically consider giving it extra regions. by which I mean, for example, create a region which is given information on the brain ie the information the reasearchers are lookng at. not all of it, but at least the map of neural activity. then connect that region with the visual cortex. The point being to allow the simulated consciousness to "see" how it's brain functions. That way, it can give direct feedback.

Once you build the circuit, how do you then model the dynamics of the morphology of the "circuitry" itself, that is, how the neurons re-wire themselves based on learning. If the circuitry is static, and the only dynamics are those of the circuit, namely, the cumulative firings between neurons, the brain is never really learning. Am I right? In other words, the brain architecture changes over time. How do you account for this?

@Udinbak 14 жыл бұрын

when they activated it, it began experiencing and thinking. Learning is provided by experience. the moment they showed it a flower, it started to think about the flower and in the process learned about the shape and colour, but since it's out of context (imagine complete sensory deprevation, then suddenly you see a flower) it's ability to "learn" is limited.

@Udinbak 13 жыл бұрын

@Udinbak cont2. The region would have to be passive at first in order to train the new brain to understand the sensory experience, then active control gradually increased while the mind becomes accustomed to making self adjustments. safety protocols in place of course. active and passive control at the early phases would be counter productive, since the young mind would exploratorially make potentially damaging alterations which could render the mind insane. or the equivalent.. just a thought..

the reason the moon 'looks' or 'seems' larger when it's near the horizon is due to a lens magnification effect caused by the light from it traveling through a larger section of the earths atmosphere. another cool exercise for your brain- when you see part of an object, but the majority is hidden out of your view, your brain can finish the object and represent it in your mind. i find this to be a very important clue to how the universe around us is represented.

Fascinating. If we are confined in a bubble or territorial space known as the universe and it provides at the extreme human possible extension of his potential, then it it could be seen as a deliberate design for "milking" / nursery / isolation virtual room for potentialities. In the layman's term if we keep on zooming neurons, we would be looking at a quantum representation of ourselves. Perhaps that is how we are created.. just a hypothesis among many other possibilities,

I agree, but it is hard to remain as open as most people when you are an "intellectual" free thinker, because one's subject of intellect often requires that person to dedicate a majority of his life to master the subject objectively. As a result, it would be expected for that person to be quite reserved to his theories. Yes, it is possible to remain still open despite that. It takes a great person. And that's a lifelong journey, irrespective of intellect.

Seeing as these simulations are run on computers, and thus are completely and understandably deterministic, any simulation you run on it can be perfectly recreated at any time.

It makes perfect sense if you don't intend on being mystical. The 'projection' is just the brain's comprehension of the world, which is translated to motor output, which produces new input and further 'projections' ad infinitum. So yes, it's infinite in a sense, much like any other piece of non-halting computer software or other information processes for that matter, until it is forced into conclusion through an external force of nature.

Right, but the point of what he was saying with all the perception stuff was that you only believe you can think infinitely. If you have a single neuron and you stimulate it, all it can know or think is either "yes" or "no". Through millions of these networked together a more complicated "infinity" emerges. There is no magic in your brain. If it can think of infinity, then there is a reason for it, and that reason can be measured / understood / reproduced.

one computer equals one neuron but linking 10,000 computers or a million computers for that matter together will always give it a finite number of thought that is possible. A brain or one neuron for that matter is not finite but holds the possiblity to think infinitly. A person can and have thought of impossible things thoughout history, therefore the brain has the capacity to be infinite. That is something that computers can never do, is to think infinitively.

"That is kind a postulate that heart is just a pump, like so many others. You can hold on to it if you it gives you peace." Are you saying the heart is NOT a pump?! I don't "hold on to it" because it gives me peace -- holding beliefs because they feel good is antithetical to science -- I hold that belief because it's a fact. "Please allow me see science in context of humanity." How could you not? Science was CREATED by humanity, the entire methodology is deeply rooted in our humanity.

the brain may be constructed, however the "observer" cannot. the brain is just a processor that translates in this case visual information (light) coming through the senses (eye) into pulses as shown. It is not the brain that sees, it is "you" (some call it consciousness, soul) the observer that see and understand its reality. it is the same observer that consciously decides to make a certain decision (move one finger and not the other for no reason)

Which manifests how fast at the nano scale the brain is working, even before the eyes have seen the actual object, the mind is already infering and comong up with perceptions which can be verified by the eye. All of which happens in a split second. I remember when MIchio kaku was asked, " is the human brain a nano computer?, Michio answered no in a subtle way. What H.
