Zebrafish optic chiasm

Light microscope image of an abnormal zebrafish embryo which has been stained with anti-tubulin antibody to show the nerve cell processes from the eyes to the brain. In this Noi mutant embryo the nerves do not all run tightly bundled in the postoptic commissure on the way to their target brain regions as they are meant to. See B0001087. Credit: R. MacDonald & S.
