AI re-creates what people see by reading their brain scans
"As neuroscientists struggle to demystify how the human brain converts what our eyes see into mental images, artificial intelligence (AI) has been getting better at mimicking that feat. A recent study, scheduled to be presented at an upcoming computer vision conference, demonstrates that AI can read brain scans and re-create largely realistic versions of images a person has seen. As this technology develops, researchers say, it could have numerous applications, from exploring how various animal species perceive the world to perhaps one day recording human dreams and aiding communication in people with paralysis.
Many labs have used AI to read brain scans and re-create images a subject has recently seen, such as human faces and photos of landscapes. The new study marks the first time an AI algorithm called Stable Diffusion, developed by a German group and publicly released in 2022, has been used to do this. Stable Diffusion is similar to other text-to-image “generative” AIs such as DALL-E 2 and Midjourney, which produce new images from text prompts after being trained on billions of images associated with text descriptions.
For the new study, a group in Japan added additional training to the standard Stable Diffusion system, linking additional text descriptions about thousands of photos to brain patterns elicited when those photos were observed by participants in brain scan studies."
