Neural coding in the cat retina

The output of the cat retina is conveyed to the brain by the axons of ∼170,000 retinal ganglion cells that together constitute an optic nerve. Ganglion cells come in a number of varieties with the result that the message conveyed along the nerve to the brain is partitioned into a number of components. In the paper some key discoveries about neural coding in the cat retina are reported and used to illustrate how efficient the retina is at encoding visual information.
