EyeWire is a game created to help map the brain. It is being led by scientists in the Seung Lab at MIT played by over 225,000 people in 150 countries. Players are challenged to map branches of a neuron from one side of a cube to the other in a 3D puzzle. Players scroll through the cube and reconstruct neurons with the help of an artificial intelligence algorithm developed at Seung Lab at Princeton University. One of the world's largest and fastest-growing citizen science projects, EyeWire gameplay advances neuroscience by helping researchers discover how neurons connect to process visual information.
