title: [Neurons of the edible snail involved in controlling the rhythmic movements of the pneumostome].
abstract: Three neurons in left parietal ganglion of Helix pomatia have been described that can have a synchronous burst activity and involve rhythmic movements of the pneumostome. It is shown that the burst activity of these cells is a result of synchronous giant IPSP in one case and of generation of the membrane potential slow waves in another one. There is no synaptic or electrical connection between three cells. Serotonin stimulates generation of the membrane potential waves and burst activity by all three neurons. Investigation on isolated cells shows that these cells are not endogenic oscillators. Isolated neurons never have the burst spike activity, but only pronounced regulated one. Study on semi-intact preparations shows that the above neurons control rhythmic movements of the pneumostome.
