Turbellarian flatworms lend themselves to neurobiological investigations using intracellular iontophoresis of Lucifer yellow provided that one is able to anesthetize the animal and expose the nervous system. This paper details the methods used with the polyclad Notoplana acticola and the rhabdocoel Mesostoma ehrenbergii. Marine turbellarians can be(More)
We investigated the neuronal configurations of brain cells in the rhabdocoel flatworm Mesostoma ehrenbergii and compared them to those of the polyclad Notoplana acticola to determine neuronal synapomorphies for these different flatworm clades. The fluorescent dye Lucifer yellow was used to fill and visualize cells in the brain of M. ehrenbergii. The(More)
