ABSTRACT
The nervous system of daughter sporocyst of D. pseudospathaceum is described on a
basis of acetylcholinesterase activity, histofluorescence of biogenic amines and serotonin
immunoreactivity. Description of the posterior part of the nervous system is added to the hitherto
described brain ganglia and irregular network of nerve fibres surrounding anterior end of the
sporocyst. The immunoreactivity of 5-HT was observed in laterally situated main nerve cords,
which run along the whole length of the body and unite at its posterior end. Some ramifications of
the main cords were also visible. A possible role of messenger molecules observed in daughter
sporocyst nervous system is discussed.
