Virtual Reality is brain science... but it ain't rocket science

good video

lol; it might get "boring"? after a week! maybe a year??!!  rof just hillarious

What is your proudest achievement in the service of humanity?

[andrewrberkshire]

I always knew you were a dumbass, but your lack of understanding of the complexity of the nervous system really betrays you. You're borderline retarded.

[Mjhavok]

Nerve cells are neurons.

[vinbuik]

This brain scientist doesn't know what the fuck he's talkin about. There are only 10 million sensory neurons that need to be interferred with. With nanotechnology, these neurons can be intercepted. Atleast 5000 years he says, he pulled that number completely out of his ass. The Blue Brain Project in Switzerland is supposed to have the entire human brain mapped out and recreated in the computer by 2015.

So what's the 'code' that produces the correct stimulus to create a specific effect? Is the code the same for every brain? While BBP is a tremendous scientific effort, you're interpretation that it will lead to a perfect interface to create a virtual world is tenuous at best. Right now the goal of the project is to create a map to research cures for disorders and disease. As the old saying goes, 'the map is not the territory'.

[vinbuik]

So basically, first you would scan the subjects' brain in real time via higher resolution mri, or terahertz passive radiation sensors, etc.

simultaneously you would expose the subject to a range of sensations (punch them, tickle them, yell at them, jerk them off). Next you would give the subject drugs, or use nanotech to destroy the newly formed association neurons that resulted from that stimulus (as not to corrupt the future input).

[vinbuik]

Then you would put the synaptic interceptors in the subjects head. They would recieve data wirelessly from the simulation construct. The simulation would recreate all the previous sensations that had occured in the sensor chamber. You would record the descrepancies between the real world and the simulated one and adjust the artificial synapse firing accordingly. Tune those suckers like you would tune a radio. From those base sensations, you could extrapolate all human experiences.

[cehbeach]

That's like saying you can learn to play a guitar by smashing it against the wall. Your process includes inducing 'real life' pains that are excruciating. Is your ethics okay with that? Once again what's the 'code' to fool the brain into thinking it just got punched in the groin? Point remaining that the reach is exceeding the grasp in this discussion. I don't even want to contemplate the experimentation necessary to 'calibrate' these sensations.

[vinbuik]

You record what happens in the subjects' head (the amount of synapses firing + the rate) when they get kicked in the groin. Then in the simulation when they are kicked in the groin a similar synapse firing algorythm is run. But like I said before, I don't think you would need to subject the subject to all of these specific excruciating pains in the real world, you could use a model (Blue Brain Project) and extrapolate the full range of sensation. You would only need a sensation base to work from

[qizalia]

What a drooly dweeb, oversexed neeeding it , jeez get tired of coming already.

[brightleader]

what about Coronal mass ejection which causes major blackout which makes virtual reality a total failure...because virtual reality machines would be shutdown for weeks which would kill billions and billions of brains

[vinbuik]

Electronics based on carbon nanotubes would not be suceptible to emp, as they can be designed to only let one electron through at a time, a power surge would not be possible.

[bobcatofthewind]

it's totally impossible for carbon nanotubes to have anytype of defects ???is that what your telling me and nothing can go wrong...

[vinbuik]

With molecular manufacturing, the nanotubes would be atomically precise, there would be no defects. If molecular manufactoring (nanofactories) turns out to be a flop, simply create carbon nanotubes from the current top down chemical engineering method, and organize them so that the system has adequate redundancies. Current power / data grids are far far more vulnerable than what is to be expected in the next 10 to 20 years.

[bobcatofthewind]

your mentally ill if you think nanotubes are a perfect tool.....what i read about nanotubes has a few defects...but you chosen to ignore those defects

[jonesr999]

VoicesInTheHead was "demonstrating his heritage"?

That would be his inferior Hispanic heritage, right? His dirty Mexican heritage?

And you wonder why people think you're a racist, Inmendham.

[SuperiorMind]

Reminds me of an electronic cigarette experiment I remember reading about which could ease the craving and produce the same sensation as a real cigarette - without the tar and all that other bad stuff.

[TheSuicidalOptimist]

Precisely we do not need to redesign the brain or manipulate any of it' core components. The 'brain' cannot make a value judgement on where a stimuli comes from. We see a pig via the eye or we stimulate the optic nerve to believe it sees a pig. To the brain there is no difference. How else could we hallucinate? How could we see things that do not exist? 5 stars!
