BBC: In a paper in the latest issue of Nature, Caltech’s Moran Cerf and his collaborators report experiments that directly probed how our imaginations can shape, and even override, what our senses tell us. Cerf’s team looked at the output from detectors attached to single neurons in the brains of 12 epilepsy patients. The patients were shown hybrid images of actors Josh Brolin and Marilyn Monroe and asked to “see” one or the other—that is, to mentally change what was before their eyes. Having already determined which neurons hold either image, Cerf and his team could tell that the patients could reliably override the hybrid image and “see” the image of the requested actor. According to Cerf, his findings suggest that it might be possible one day to record people’s dreams.
An ultracold atomic gas can sync into a single quantum state. Researchers uncovered a speed limit for the process that has implications for quantum computing and the evolution of the early universe.
