A glial cell is a cell that supports and protects neurons. They serve to hold neurons in place, supply nutrients and oxygen to neurons, insulate one neuron from another, destroy pathogens and remove dead neurons.

Müller cell

One kind of retinal glial cell, the Müller cell, is of importance in transporting light from the surface of the retina to the photoreceptors. Vertebrate retinas have their photoreceptors at the back of the retina, with masses of neurons, blood vessels, and other cells between the photoreceptors and incoming photons. Müller cells act as fiberoptic light guides, allowing photons to pass through the retinal tissue relatively unimpeded.[1]

History

EyeWire

A glial cell in the EyeWire interface.

In EyeWire, glial cells have a characteristic large, swoopy, irregular structure distinct from neural cells.
