  text: 'Vertebrate movement is orchestrated by spinal inter- and motor neurons that,
    together with sensory and cognitive input, produce dynamic motor behaviors. These
    behaviors vary from the simple undulatory swimming of fish and larval aquatic
    species to the highly coordinated running, reaching and grasping of mice, humans
    and other mammals. This variation raises the fundamental question of how spinal
    circuits have changed in register with motor behavior. In simple, undulatory fish,
    exemplified by the lamprey, two broad classes of interneurons shape motor neuron
    output: ipsilateral-projecting excitatory neurons, and commissural-projecting
    inhibitory neurons. An additional class of ipsilateral inhibitory neurons is required
    to generate escape swim behavior in larval zebrafish and tadpoles. In limbed vertebrates,
    a more complex spinal neuron composition is observed. In this review, we provide
    evidence that movement elaboration correlates with an increase and specialization
    of these three basic interneuron types into molecularly, anatomically, and functionally
    distinct subpopulations. We summarize recent work linking neuron types to movement-pattern
    generation across fish, amphibians, reptiles, birds and mammals.'
