Image of the Week: Seeing the blind spot

These multicolored tentacles are actually blood vessels emerging from an eye's blind spot. Also called the optic disc, this is the spot where the optic nerve attaches to the retina. The confocal micrograph shows the optic disc in black, cells lining the blood vessels in red and vessel contents in green. Retinal cells are stained blue.
