In a reduced preparation of Planorbarius corneus consisting of the CNS and mantle complex, both the dopamine precursor L-DOPA and the serotonin precursor 5-HTP have been found to be able to induce and maintain rhythmic pneumostome (PN) movements coupled, in a neurotransmitter-specific manner, to fictive cyclic locomotion. Following transection of the pedal commissures, the pharmacologically induced movements of the PN were coordinated with the locomotory rhythm generated by the left pedal ganglion.
