Koch) and Marpissa muscosa (Clerck) (= M. rumpfi (Scopoli)] were studied using histochemical methods. Enzyme activity occurred in the neuronal perikarya and in varying intensity in the structures of the neuropile mass, but only when dopamine, adrenaline [epinephrine] and noradrenaline [norepinephrine] were used as substrates. The optic centers of the spider brain normally exhibited relatively strong enzyme reactions when compared with the staining intensity of the rest of the nervous system. The neuronal cell bodies contained numerous granules of yellow-green fluorescence. Monoaminergic fluorescence of the neuropile was generally a weak green. The optic masses of the hunting spiders, the anterior bridge, several commissures of the ventral cord and the neural lamellae showed a slightly higher fluorescence intensity and single fluorescing granules. The presence of catecholamines in the spider nervous system is indicated.},

	abstract = {The CNS of web-building spiders (Araneidae, Agelenidae) and hunting spiders (Lycosidae, Salticidae) were tested for nonspecific and specific phosphatases. Acid phosphatase exhibited weakly to moderately positive reactions in the neuronal cell bodies and in the neuropile fiber mass of all species investigated. Alkaline phosphatase could only be demonstrated in the external and internal neural lamellae of the brain and ventral cord of several specimens of the araneid species investigated. Tests for thiamine pyrophosphatase were negative with both the Pb and Ca-Co methods. Distinctive positive reactions for ATPase were visible in the nervous system of all the species used, being especially strong in the optic ganglia of the hunting spiders. The demonstration of ATPase was only possible when applying the Ca-Co method after Padykula and Herman, while the Pb method after Wachstein and Meisel did not produce any staining reaction at all. Controls of the histochemical reaction showed that the enzyme was activated by Ca2+ and inhibited by sulfhydryl destroying reagents (e.g., PCMB [p-chloromercuribenzoate]), but was insensitive to ouabain. It could be probably classified as a mitochondrial proton-translocating ATPase.},
