Hemispheric raises $52M for brain-reading AI

Hemispheric, co-founded by FaceID co-inventor Gidi Littwin and neuroscientist Hagai Lalazar, raised $52 million. Its 6-billion-parameter model Descartes was trained on 250,000 hours of brain data from 100,000 people. The startup aims to diagnose conditions like PTSD and Alzheimer's using a 15-minute EEG headset test.
