[Synchronization of the work of pedal ganglia of pteropod mollusks during locomotion].

Two wings of the marine mollusc Clione limacina oscillate synchronously during swimming. These movements are controlled by pedal ganglia. Synchronization of rhythmic activities in the ganglia is produced by interneurons of groups 7 and 8 whose axons pass to the contralateral ganglion through the pedal commissure. After destruction of commissural pathways, rhythmic activities in the two ganglia become independent. The synchronization restores with the regeneration of axons of interneurons from groups 7 and 8.
