The video above is an excellent quick overview of the comprehensive imaging of a female fruit fly brain at nanoscale resolution. The video was created by the lead research team at Janelia.
A fruit fly brain is composed of about one hundred thousand neurons and is now the largest brain compressively imaged at nanoscale resolution using an electron microscope. One adult female fruit fly gave her all so that we may see every one of her neurons and the way they are connected into circuits. Details were published a couple of days ago in “A Complete Electron Microscopy Volume of the Brain of Adult Drosophila melanogaster” (published July 26, 2018 in Cell).
