A device that reveals what a person sees by decoding their brain activity could soon be a reality, say researchers who have developed a more sophisticated way to extract visual stimuli from brain signals.
Scientists at the University of California, Berkeley, US, developed a computational model that uses functional MRI (fMRI) data to decode information from an individual's visual cortex – the part of the brain responsible for processing visual stimuli.
"Our research makes substantial advances towards being able to decode mental content from brain activity as measured using fMRI," Kendrick Kay, a co-author of the study, told New Scientist. "In fact, our results suggest it may soon be possible to reconstruct our visual experiences from brain activity."
