Doesn't reconstruction like this rely on the decoding mechanism being trained on the original images? This doesn't scale to reconstructing any visual image, only to differentiating between those the decoder has already seen.

It doubt very much that it reconstructs from the visual cortext. That is a non-trivial task with fMRI which has a much higher SNR than EEG.

Here's their preprint.

It's basically using a pretrained VGG network as a latent space, which lets them synthesize images.
