[Bimodal effect of serotonin on glutamate-induced ionic currents in Helix pomatia neurons]

Bimodal effect of serotonin on glutamate-induced ionic currents was found in experiments on Helix pomatia neurons under voltage clamp conditions. The results of a 1 min exposure to theophylline, dibutyryl-cAMP or imidazole have shown the participation of intracellular processes connected with adenosine 3':5'-cyclic monophosphate and calcium ions in this bimodal effect of serotonin.
