I want to see a cats POV when its startled by a cucumber (Youtube has lots of examples). A theory is that part of the brain mistook it for a snake. Also research on "constant bearing, decreasing range (CBDR)" where drivers may not notice another car/cycle in a perfectly clear crossroads till its too late.'

For something like these kinds of reflexes, my understanding is that the response comes from the central nervous system, even before the brain has had the chance to fully process the input. This shortcut makes one avoid, say, burns or snakes, quicker than if it required the brain. Still, I agree with you that seeing what a cat sees (here or anywhere) would be awesome.

I hope one day we can turn this on for coma patients and see if they're dreaming or otherwise processing the world.

Maybe I missed this, but isn't the underlying concept here big news?

Am I understanding this right? It seems that by reading areas of the brain, a machine can effectively act as a rendering engine with knowledge on colour, brightness etc per pixel based on an image the person is seeing? And AI is being used to help because this method is lossy?

This seems huge, is there other terminology around this I can kagi to understand more?

AI is the method. They put somebody in a brain scanner and flash images on a screen in front of them. Then they train a neural network on the correlations between their brain activity and the known images.

To test it, you display unknown images on the screen and have the neural network predict the image from the brain activity.

This requires intrusive electrodes, "fMRI visual recognition", https://scholar.google.com/scholar?q=fmri+visual+recognition

There are startups working on less intrusive (e.g. headset) brain-computer interfaces (BCI).

fMRI isn't the one with the electrodes, it's the one with the giant scanner and no metal objects in the room.
