About this work
Retinal ganglion cell axons cross at the optic chiasm as they make their way to the to the optic tectum. Confocal micrograph of the brain of a transgenic 60 hour old zebrafish embryo viewed from a ventral aspect. Some neurons express the green fluorescent protein (GFP) - (green) under the control of a specific promotor, which drives expression in retinal ganglion cells, neuromasts, habenulae and the optic tectum. Tracts and axons have been labeled using antibodies against tubulin (red). Width of image is 500 micrometres
