Summary
The distribution and activity patterns of acetylcholinesterase in the central nervous system of araneid and agelenid spiders have been studied. Enzyme activity was limited to the neuropile mass. The araneid and agelenid species investigated exhibited largely similar acetylcholinesterase activity in different parts of the nervous system. Enzyme reactions were relatively less intense in the optic ganglia; the central body showed only weak to moderate reaction stainings.
