description

Some experimental results on action potential (EKG) in the pacemaker system of the tunicata heart (Ciona intestinalis) are presented. Synchronous records of both end and central heart regions show a spontaneous chance of the electrical activity in the middle of the heart tube, just before the periodic reversal of the direction of the pulsating wave starts. Extra systoles in the central pacemaker influence the terminal centres and provoke reversal.
