Distribution and functional organization of glomeruli in the olfactory bulbs of zebrafish (Danio rerio)

Abstract The cover image shows the paired olfactory bulbs of an adult female zebrafish (Danio rerio). The image was obtained through a novel in toto immunohistochemistry protocol explained in Braubach, Fine and Croll in this issue. The tissue was labeled with antibodies against the molluscan blood protein, keyhole limpet hemocyanin (red), and the calcium binding protein, calretinin (green). Axons that enter the olfactory bulbs via the olfactory nerve (bottom) converge on different target areas, which differ in their neurochemistry and the numbers and morphologies of olfactory glomeruli contained within each region.
