Eyewire
Eyewire is a citizen science game from Sebastian Seung's Lab at Princeton University. It is a human-based computation game that uses players to map retinal neurons. Eyewire launched on December 10, 2012. The game utilizes data generated by the Max Planck Institute for Medical Research.

Eyewire gameplay is used for neuroscience research by enabling the reconstruction of morphological neuron data, which helps researchers model information-processing circuits.

Gameplay
The player is given a cube with a partially reconstructed neuron branch stretching through it. The player completes the reconstruction by coloring a 2D image with a 3D image generated simultaneously. Reconstructions are compared across players as each cube is submitted, yielding a consensus reconstruction that is later checked by experienced players.

Goal
Eyewire is used to advance the use of artificial intelligence in neuronal reconstruction. The project is also used in research determining how mammals see directional motion.

Methods
The activity of each neuron in a 350 × 300 × 60 μm3 portion of a retina was determined by two-photon microscopy. Using serial block-face scanning electron microscopy, the same volume was stained to bring out the contrast of the plasma membranes, sliced into layers by a microtome, and imaged using an electron microscope.

A neuron is selected by the researchers. The program chooses a cubic volume associated with that neuron for the player, along with an artificial intelligence's best guess for tracing the neuron through the two-dimensional images.
