NEvo (EPFL/Johns Hopkins): AI evolves custom videos to maximally drive activation in targeted brain regions (recent research drop, HN traction).
“AI just evolved the ultimate brain-hacking video for any region of your visual cortex. The results are deeply strange.”

Why It Matters
Concrete computational neuroscience artifact--genetic algorithm + AI video gen creates "optimal" evolving clips (e.g., hypnotic social scenes for pSTS, patterns/motion for V1, faces for FFA) that hyper-activate specific brain areas far better than natural stimuli; maps dynamic/social visual selectivity while raising questions about engineered perception, art, advertising, or neuro-influence.
Evidence
nevo-project.epfl.ch project page and demos; HN thread and X shares (e.g., researcher posts showing evolved clips outperforming natural videos).
