General and detailed organization of the nervous system of Lobatocerebrum riegeri n. sp. as seen with CLSM. DAPI in cyan, FMRF in purple and acetylated α-tubulin in yellow or “glow”. All images are maximum intensity projections of a subset of the original image stack on various locations of the body if not specified below a Dorsal view of a juvenile specimen, b Lateral view of an adult, pharyngeal ganglia outlines in red, details of the same specimen as (c), c Three different substacks of an adult specimen pieced together for an overview-picture. The specimen is twisted and some portions are laterally oriented and others dorso-ventrally oriented , d Dorsal view of the details of the brain, e Juvenile showing the general organization of the nervous system. Notice the presence of only three trunk commissures, f Dorsal view of the details of the brain in a juvenile. Details of the same specimen as (e), g Dorsal view of details of the origin of the median nerve cord in a juvenile. Details of the same specimen as (e).
