Cover picture: Three-dimensional volume rendering of the first optic neuropil, or lamina, of the Drosophila optic lobe labeled with anti-endophilin (Endo; green) and anti-synaptobrevin (Syb; red). Precise modules of this neuropil, called cartridges, comprising six photoreceptor terminals that innervate lamina monopolar cell interneurons, are immunoreactive for Endo and Syb (orange/yellow). Note, however, that Endo is also present in unidentified cells of the lamina cortex surmounting the lamina. (This image was prepared by P. Robin Hiesinger.)
