title: [Reciprocal modulating effect of serotonin and dopamine on neurons of rat spinal ganglia].
abstract: It was found in experiments on isolated dorsal root ganglion neurons of rats that dopamine (10(-8)-10(-6) Mol/l) potentiated depolarizing neuronal responses evoked by injection of 5-hydroxytryptamine from micropipette. Similar concentrations of 5-hydroxytryptamine (10(-8)-10(-6) Mol/l) potentiated neuronal depolarizing responses evoked by dopamine. Potentiating action of monoamines on combined neuronal responses depended on concentration and was inhibited by antagonists of dopamine (haloperidol) and 5-hydroxytryptamine (deseril) receptors. This effect of monoamines had postsynaptic nature and was bound with an increase of Ca2+ and cAMP intracellular concentrations.
