It's the largest and most detailed rendering of neural circuits in a mammalian brain. This new, precise map of the vision centers of a mouse brain promises to accelerate the study of normal brain function: seeing, storing and processing memories, and navigating complex environments. As importantly, it will deepen the study of brain disorders in anatomical and physiological terms. This project was co-led by Sebastian Seung, the Evnin Professor in Neuroscience and a professor of Princeton Computer
