[Neurons of the pedal ganglia of a pteropod mollusk regulating locomotor generator function].

Neurons whose excitation affected the locomotory rhythm were recorded in the isolated pedal ganglia of the marine mollusc Clione limacina. Some of these neurons generated "plateau" potentials, i.e. they remained depolarized for a long period after termination of the initial depolarizing current. A role of the command neurons in the motor behaviour of Clione is discussed.
