Hi Telmo Menezes It would be good if they showed a video clip.

Hi again Roger, It's a bit better than that. A machine learning algorithm is trained to decode neural activation signals. The training is performed by showing the subject known images, and letting the algorithm learn how their neural activity maps to these images. The real magic happens when you show them new stuff, that the algorithm wasn't trained for. To me, the most impressive stuff here is when it fails. If you pay attention to the videos, you will see the algorithm decoding different (but similar images) from what the one being shown to the subject. For example, when faces are shown, different faces are decoded and then start correcting. My speculation is that we are actually seing visual memories conjured by the brain in its pattern matching attempts. My favorite is the ink blot exploding, where you can see the brain anticipating the explosion, so you get to see a visual of the subject imagining a likely future state.

If it's fMRI, you don't see the riginal video clip as an eye would see it, you see an image of brain activity.

My memory is the identity of my 1p and is what my 1p sees. This is perhaps the most serioous problem of comp. Frankly .... I can understand people not convinced that a computer can have a quale associated to the memory, but memory and personal memory does not pose any problem in computers. Then I have explained why they have a quale too. This is not even theoretical anymore. Here's a rather compelling example of visual information in human brains being uploaded into a computer: http://gizmodo.com/5843117/scientists-reconstruct-video-clips-from-brain-activity? -- You received this message because you are subscribed to the Google Groups "Everything List" group.
