This is deep in uncanny valley. Can it reconstruct images from our imagination as well? What about images from dreams? How far are we away from video?
If you know the series Max Headroom you probably know what I'm getting at.
There is an episode about dream-harvesting which Wikipedia summarizes like this[1]:
"In an attempt to get an edge over the major networks, a subscription cable channel turns to airing recorded dream sequences. When Carter begins researching a story on dream recording, he learns that the process can have fatal side effects for the donors."

- mjburgess 6y agoYes, none of that. This is just picking up the imprint of a direct perception; it is essentially equivalent to just photographing the reflection of the TV in your eye. This isn't "decoding" any internal information actually present anywhere in the brain. It is showing, at best, that visual input "lands somewhere" in the brain -- but is not showing any of the brain's processing, nor any of the impact of the visual. It's just, essentially, looking at the terminal node of the eye.
- ASalazarMX 6y agoThe model can't guess your thoughts unless it is trained with your brain activity (fMRI, EEG). After training, you feed it more brain imaging and see what comes out. I don't know if this could be applied to, say a prisoner in Guantanamo, strapped to a fMRI and forced to look at images while the model trains on his brain activity. The subjects in these experiments are cooperative, while a uncooperative subject could try to blur his sight, meditate, think of loud songs, a movie, food, etc., to dissociate their vision from their thoughts.
