AI Turns Brain Activity Into Sentences
Researchers have created a âmind-captioningâ AI that translates brain activity into full descriptive sentences, not just keywords.
Using fMRI scans and deep-language models, the system decodes what people see or imagine with surprising detail, effectively narrating mental scenes. Beyond its sci-fi appeal, the technology could unlock new ways to understand perception and help those with speech loss regain communication.
You can make LLMs more creative by training them on human "creativity signals" (novelty, diversity, surprise, quality). Result: Even small models score higher on all 4 creativity dimensions simultaneously.
Looks like we can optimize AI for creativity just like any other metric

Static networks are good but how about their dynamics? (nothing is static in the brain)
They temporally cycle.
