Representatives of the phylum Mollusca have long been important models in neurobiological research. Recently, the routine application of immunocytochemistry and gene expression analyses in combination with confocal laserscanning microscopy has allowed fast generation of highly detailed reconstructions of neural structures of even the smallest multicellular animals, including early developmental stages. As a consequence, large-scale comparative analyses of neurogenesis—an important prerequisite for inferences concerning the evolution of animal nervous systems—are now possible in a reasonable amount of time. Herein, we describe immunocytochemical staining and in situ hybridization protocols for both, whole-mount preparations of developmental stages—usually 70–300 μm in size—as well as for vibratome and cryostat sections of complex brains. Although our procedures have been optimized for marine molluscs, they may easily be adapted to other (marine) organisms by the creative neurobiologist.
