Mriganka Sur is a neuroscientist whose research transformed scientific understanding of brain plasticity and sensory processing. At Massachusetts Institute of Technology, he conducted pioneering experiments demonstrating that the neocortex can reorganize and adapt in response to new inputs, revealing an unexpected capacity for neural rewiring. His work challenged long-held assumptions about fixed brain function and helped reshape modern neuroscience. Sur’s discoveries have deepened understanding of learning, development, and recovery from brain injury, influencing both basic research and clinical approaches to neurological disorders.
