   Weizmann's Brain-IT AI reconstructs viewed images from fMRI scans

   Researchers at the Weizmann Institute of Science, led by professor Michal Irani, built Brain-IT, a model that uses fMRI scans to reconstruct images a person is viewing — and also works in reverse to predict brain activity for a given image. The team says it outperforms earlier methods on image content and details such as composition and color, and needs only about one hour of fMRI data from a new subject to match results other approaches reach with 40 hours of recordings. The work remains confined to lab settings; the researchers hope it could eventually help people who cannot communicate and, more speculatively, decode dreams.

   AI Reconstructs Viewed Images From Brain Scans

   Researchers at Israel’s Weizmann Institute of Science developed an AI system that uses high-resolution fMRI data to reconstruct images people are viewing, combining brain decoding with an image diffusion model. The team trained it on data from eight participants who viewed about 9,000 images each, and reports that the system can be calibrated to a new participant with about one hour of data rather than the roughly 40 hours required by earlier approaches.
