Sensory systems transduce fluctuations in the physical world into patterns of action potentials which are integrated to control motor outputs. Locomotion relies on genetically determined circuits constituted by spinal interneurons and capable of generating oscillations. Local sensory information about the outside world or the internal state seem to alter thesemotor patterns by triggering, stopping or steering locomotion.
