What this can eventually mean

> control a video game character using your entire body's impulses

> record all sensory perceptions / record emotions and 'verbal' thoughts

More?

Ewww. I hate the idea. So many ways it could be misused. United states in mind here.

Please... as if someone's going to sneak an fMRI machine into your house to read your thoughts when you aren't looking.

Only fearful people reject progress because of the ways it could be "misused".

Anything can be "misused".

Things aren't intrinsically good or bad, just the situations they're in.

This is my dream... that one day, well, dreams, can be recorded. Seems like we're getting very slowly closer.

Pro: Stephen Hawking could control a robot body if they only interpret the image he's imagining!

Should it be developed? Sure. But make laws so you need consent to use it.

Actually... those are already in place. How do you think you'd end up getting an fMRI? People, this is MEDICAL EQUIPMENT. You could no sooner read a stranger's mind than you could irradiate them with X-Rays or inject them with radiotracers.

Passively observing brain activity and implanting ideas into the brain are two pretty fucking different things.

Okay, well here's how I plan to develop it. You cover the back of a subject's head with about 5000 electrodes measuring surface voltage (standard eeg stuff, but more points of reference).

The you let the subject watch movies, TV whatever, maybe browse the web, but images are going to be better than text, which is probably going to be worthless for this. So probably movies and TV.

Then the tricky part. Develop a neural network that take the input from the 500 electrodes and back-propagates the image being watched. It's tricky for the same reason that any visual interpretation network is... it needs to be consistent under small translations and rotations. In other words the screen image needs to be represented in the neural network a little closer to how the brain processes an image, rather than raw pixels.

Let the subject watch several thousand hours of tv and movies, and the neural network should be entrained. Then we should be able to see what he sees, and see what he dreams. There could potentially be seriously high resolution from the data from 500 electrodes. Can you imagine waking up and seeing computer images from your dreams?
