[Subsynaptic modulation of chemical stimulation transmission by metacerebral neurons in the buccal ganglia of mollusks].
Stimulation of giant metacerebral serotonin-containing cell LMc1 in Helix pomatia was studied for its effect on responses of buccal cells LBc2 and LBc3 to stimulation of buccal nerves. Stimulation of cell LMc1 modulated those responses either increasing or decreasing them. Results of applications of serotonin, dibutyryl-cAMP, methysergide, d-tubocurarine and acetylcholine on cells LBc2 and LBc3 suggest that the modulation of responses of buccal cells LBc2 and LBc3 to buccal nerves stimulation by cell LMc1 was subsynaptic.
