Neural Control of Swimming in a Vertebrate

Neural Control of Swimming in a Vertebrate

An excitatory drive to the spinal cord neurons supplying rhythmic locomotor output in swimming was demonstrated in paralyzed late Xenopus embryos. The motor system for a single muscle can independently generate rhythmic motor discharge with the normal swimming cycle period.
