First 3D map of fruit fly's brain network created
Japan-based scientists have created what they claim is the world's first 3D map of a fruit fly's brain network. They pickled a fly brain in silver dye, bombard it with X-rays and measured their scattering intensity in different directions to produce the image intensity map. The map, that took 1,700 man hours to build, displays 100,000 neurons with 600-nanometre resolution.
