Abstract

The presence of acetylcholinesterase and choline acetyltransferase, enzymes involved in acetylcholine metabolism, has been shown in twelve species of rotifers. Both enzymes have been visualized by histochemical staining in live animals, and acetylcholinesterase was also isolated by acrylamide gel electrophoresis. All the known ganglia of rotifers as well as some sensory nerve endings have been found to contain these enzymes. Preliminary experiments aimed at the detection of norepinephrine and tyrosinase, an enzyme involved in catecholamine metabolism, were unsuccessful.
