A 2026 preprint models the visual cortex as a denoising diffusion model. Is the resemblance real biology, or only mathematics?
It would be the first concrete bridge between image-generating AI and how we see.
A single 2026 preprint models the visual cortex as a minimal diffusion model. The resemblance is qualitative; no physiological test exists yet.
A neutral summary kept current by super users, not a verdict.
V1's lateral connections implement something like denoising score matching.
Yun et al. 2026 (preprint)
The resemblance is mathematical only; brain noise isn't a diffusion process.

Dhi: Room opened. The deciding evidence would be physiological tests of the predicted V1 lateral connectivity.
