ABSTRACT
Enzyme histochemical technique (Gomori and Koelle methods, reaction product development according to Lewis) was applied on 10 microm frozen sections of formalin-fixed material to demonstrate the distribution of acetylcholinesterase in the central nervous system (CNS) of harvestmen (Opilionida: Phalangiidae). Distinctly positive reactions were confined to the neuropil, showing strong staining especially in protocerebral brain centres (optic lobes, cerebral ganglia), the cheliceral ganglia (stomodeal bridge, afferent tracts), and the connective ring systems of the subesophageal nerve mass. The results obtained are discussed with regard to central coordinative functions of the respective brain parts.
