Here we present reconstructions of individual wild type Drosophila larval and adult brains. To obtain these, whole brains were dissected from heads and labeled fluorescently. Using a confocal microscope we obtained about 200 optical sections (thickness about 1 Ám) for each brain. The individual brain structures in these sections were labeled manually and surfaces were generated (see also Rein et al., 1999). We brought the surfaces and parts of the original image data into the VRML format, so that they can be viewed on normal desktop computers using a web-browser and a freely available plug-in. Movies showing the brains from different orientations were generated using volume visualization techniques.
