Coaxing injured nerve fibers to regenerate by disabling 'brakes' in the system
Brain and spinal-cord injuries typically leave people with permanent impairment because the injured nerve fibers (axons) cannot regrow. A study from Children's Hospital Boston, published in the December 10 ...

How the retina works: Like a multi-layered jigsaw puzzle of receptive fields
About 1.25 million neurons in the retina -- each of which views the world only through a small jagged window called a receptive field -- collectively form the seamless picture we rely on to navigate our environment. ...
