Groundbreaking AI system reads minds and produces text without implants

Researchers from the University of Texas at Austin have created a mind-reading AI system that can take images of a person’s brain activity and translate them into a continuous stream of text. Called a semantic decoder, the system may help people who ar… Continue reading Groundbreaking AI system reads minds and produces text without implants

Brain activity could predict who is most likely to get PTSD

When it comes to post-traumatic stress disorder (PTSD), much of the clinical research focuses on improving the condition rather than predicting it. However, a new study carried out at Tufts University has just uncovered a brain marker that seems to sho… Continue reading Brain activity could predict who is most likely to get PTSD
