We report here studies of the properties of a single neuron (CPB3c) involved in rhythmic movements in an invertebrate animal, i.e., the marine pteropod mollusk Clione limacina. Interneuron CPB3c is cerebropedal neuron “c,” whose body is located in area B3 of the cerebropedal ganglion and whose processes are directed into the pedal ganglia. The operation of this interneuron was studied during locomotion and on stimulation of individual receptor cells in the balance organs, i.e., statocysts. Interneuron CPB3c receives signals from the statocysts and from the locomotor generator, and may support the transmission of the locomotor activity pattern to the tail motoneuron in Clione. Thus, a single interneuron has all the required connections and is ideally suited to performing a coordination function.
