The preparation of the embryonic cockroach brain neuronal cultures is a complicated procedure which has been described in detail by Beadle and Lees ( ). In brief, the brains were dissected from 23-26 day old embryos of Periplaneta americana and broken up by passage through Pasteur pipettes of decreasing diameter. The cultures were initiated in a medium consisting of 5 parts Schneider s Drosophila medium and 4 parts Eagle s Basal medium, and after 7 days growth were transferred to a... 

To assess activity at the insect ryanodine receptor, pyridyl pyrazoles of Table II were tested in a calcium mobilization assay, using neurons from the American cockroach, Periplaneta americana. These studies have confirmed the mode of action to be RyR activation. Compounds D11-D17 showed exceptional potency in this assay with activity in the range of0.03-0.30 pM. The data shows the ability of anthranilic diamides to release internal calcium stores while failing to activate voltage-gated calcium channels. Furthermore, calcium mobilization induced by anthranilic diamides is blocked following treatment with 1 pM ryanodine, consistent with action at the ryanodine receptor. 

Studies of the ultrastructure of glomeruli in M. sexta have revealed pre- and postsynaptic profiles, where one pre-synaptic region is commonly associated with several postsynaptic (Tolbert and Hildebrand 1981). Pre-synaptic profiles are not only present in terminals of primary axons. Identification of second-order neurons filled with horseradish peroxidase, have shown that local interneurons also possess pre-synaptic profiles. Similar indications that information is not only received by second-order neurons but also transmitted, were previously provided by degenerating studies in Periplaneta americana and Calli-phora erythrocephala (Boeckh et al., 1970). One of three types of pre-synaptic profiles is most common in M. sexta and seems to be the predominant type in the primary axon terminals (Tolbert and Hildebrand, 1981). These are characterized by their numerous small roimd and clear vesicles, resembling cholinergic terminals in vertebrates, that use acetylcholine as a transmitter (Sanes et al., 1977).
