A two-day-old zebrafish embryo brain

These striking images show a zebrafish embryo brain at just two-days-old as seen with a Light Sheet Fluorescent Microscope.

Light sheet microscopy illuminates the specimen with a thin sheet of light and can be used to see relatively large structures in fine detail. You can see all the nerve cells and connections in the zebrafish brain stained with an antibody in red.

Being able to see embryos in this detail allows research teams at the University of Sheffield to follow the amazing process of embryogenesis, from a single cell (the fertilised egg) to a functioning animal with hundreds of different cell types.
