An identified pleural ganglion interneuron inhibits patterned motor activity in the buccal ganglia of the snail, Helisoma.
Neuron, Pl1, an interneuron that inhibits patterned motor output underlying feeding in the snail, Helisoma, is identified. The soma of neuron Pl1 is in the pleural ganglion and its axon projects through the pedal and cerebral ganglia to the buccal ganglia. A train of action potentials in neuron Pl1 suppresses rhythmic activity in the buccal pattern generator even in the presence of strong pharmacological stimulation with serotonin.
