[Motor neuron activity of the pedal ganglia of pteropod mollusks during generation of locomotor rhythms].

Activity of motoneurons from pedal ganglia of marine mollusc Clione limacina was recorded during generation of the locomotor rhythm. Motoneuron groups controlling antagonistic wing muscles are active alternatively, excitation of one group being accompanied by inhibition of the other group. Many synergetic motoneurons are electrically coupled.
