About The Cover

Cover image expansion

COVER A three-dimensional micrograph, color coded by depth, of neurons at the ellipsoid body in the brain of a fruit fly (Drosophila melanogaster), extracted from a much larger dataset encompassing the entire brain. Combining expansion microscopy with lattice light-sheet microscopy enables rapid fluorescence imaging of neural circuits and their molecular constituents over millimeter dimensions with nanoscale resolution.
