A

Acc/AQC: Accuracy

Administrator (Admin): A user who works for/with EyeWire HQ. Abilities include but are not limited to: editing cubes, moderating the chat and forum, declaring cells complete, editing the blog and wiki, and running in game competitions.

Advanced Player: A user who has passed the Lightning tutorial and has access to all active EyeWire cells. See also: Trainee

Amacrine Cell: A type of neuron in the retina. Bipolar cells make synapses onto them, and they make synapses onto ganglion cells. There is no true distinction between the dendrites and axon of an amacrine cell, the projections may be referred to as neurites (or Branches, for accuracy, or dendrites, for simplicity.

Ancestors: Scouts/scythes and admins can see the cubes (or ID of cubes) that spawned further up the branch (towards the cell body). Hit "Show" the cubes should be highlighted.

Autapse: Autapse: Autapses are synapses that a cell forms onto itself. See also: Self-Touch

Axon: The projection from the cell body that will send electrochemical signals to other neurons. Axons can be very long, and only branches at the end.

B

Bipolar Cell: A type of neuron in the retina. Photoreceptors and horizontal cells make synapses onto them and they make synapses onto amacrine and ganglion cells. Their name comes from their appearance, as they have one projection on each side of the cell body.

Black spill: (Also called dark spill or ink spill.) A trace that has leaked dye. Sometimes hard to follow. Usually looks like black spots and rivers. The trace is often rough and gappy.

Branch: A part of the trace that exits the cube. | A synonym for Neurite.

Bouton: The synaptic terminal on the presynaptic cell in a chemical synapse. It contains neurotransmitters that are released when the cell is activated.

C
