Global social and tech giant Meta has developed an AI model using MEG technology that can decode visual activity in the human brain in real-time. This non-invasive neuroimaging technique can detect brain activity every second, providing a crucial foundation for brain science and technological innovation. The technology is also expected to enhance the accuracy of AI models, aiding the development of artificial general intelligence, and potentially accelerating research in brain-computer interfaces, helping individuals who have lost their ability to speak. Researchers have verified that the generated images retain significant features.
