Scientists in Japan have developed a dream decoding system that can create a visualization of a person’s dream. Developed by researcher Yukiyasu Kamitani and his Kyoto-based team, the system uses a functional MRI to analyze brain activity and a learning algorithm to create visualizations from the brain data. While the researchers report that the system is not currently very accurate, the results are nonetheless promising and the visualizations are quite remarkable. For more on the study, see this post by the Smithsonian science blog, Surprising Science. The study was also recently featured on NPR.
