Neuroscientists decoded people’s thoughts using brain scans

Summary :Researchers have developed a system that can “read” words and ideas from a person’s brain activity as they listen to stories. In a study published in Nature Neuroscience, three participants listened to stories while having functional MRI scans to detect changes in blood flow in their brains. The researchers then used a language model built with the GPT AI system to match the patterns of brain activity to certain words and ideas. The process produced a high error rate in terms of specific words, but was able to identify the general idea being conveyed. The researchers said the system was personalised and required voluntary participation, and did not represent a threat to privacy.
