abstract：:Swimming behavior in the marine mollusc Tritonia diomedea is episodic, consisting of a series of alternating dorsal and ventral flexions initiated by a brief sensory stimulus. The swim motor pattern is generated by a network formed of four groups of premotor interneurons: cerebral cell 2 (C2), dorsal swim interneurons...
