the optic nerve is composed of axonal projections from retinal ganglion cells, neurons that receive inputs (via amacrine and horizontal cells) from the photoreceptors (rods and cones)
here ganglion cell axons (fluorescently labeled in pink) are converging at the optic disc to gather as cranial nerve I
blood vessels also enter and leave in this area, touched by the delicate arcs of astrocyte processes, shown in electric blue
