1
neuron: vision cells (rod cells - brightness;
cone cells - colour)
2
neuron: bipolar ganglion cells within the retina
(ganglion of the retina, Ganglion retinae)
3 neuron: multi-polar ganglion cells (optic ganglion,
Ganglion opticuml, whose long axons form the optic
nerve and continue in the optic tract
