The intersegmental coordination during undulatory locomotion in lamprey is characterized by a constant phase lag between consecutive segments, that is, the ratio between the intersegmental time lag and the cycle duration remains constant. It is shown that the spinal 5-HT (serotonin) system can, in a graded fashion,...
