behavior/neurological
• quadrupedal hopping gait is dominant at all locomotor frequencies
• occasional alternating gait is seen at lower frequencies
|
nervous system
• increase in axon midline crossing
|
• significantly wider gap between the central canal and the ventral edge of the dorsal funiculus
|
• wider and the distance from the ventral edge to the surface of the spinal cord is shorter; however, the total area is not different from controls
|
• chemically and electrically stimulated locomotor-like activity in isolated spinal cord preparations induces a synchronous "hopping" locomotor-like activity rather than an alternating locomotor-like activity
