SOME NOTES ON THE ORGANIZATION OF SPINAL AND SUPRASPINAL PREMOTOR NETWORKS FOR LOCOMOTION

In this introduction to the session 'Premotor networks for locomotion' the basic pattern of vertebrate locomotion, i.e. lateral undulation, and its underlying spinal circuitry will be discussed. Aspects of supraspinal networks for locomotion with emphasis on the initiation of axial movements in agnathans and anuran embryos will be briefly discussed. Finally, data on limb premotor networks in terrestrial vertebrates, particularly turtles, will be summarized.
