For generations, the brain was imagined as a factory of specialists — each neuron assigned its singular purpose. A landmark study of more than 14,000 neurons across dozens of cortical regions in mice has quietly dismantled that assumption, revealing that most neurons are versatile generalists, simultaneously processing sensation, movement, and decision-making. The finding, born from an unprecedented collaboration and a standardized dataset that made true comparison possible for the first time, suggests that the brain's power lies not in rigid division of labor, but in the rich, overlapping div
