This study shows that spinal motor populations use rotational dynamics in a low-dimensional neural manifold for locomotion, which persists after spinal cord injury and suggests an intrinsic spinal attractor mechanism.

This study examines how spinal transection and locomotor speed affect muscle synergies in cat hindlimbs, finding that while specific synergies change, the overall organization remains consistent.

This study examines changes in reflex pathways from forelimb cutaneous afferents after thoracic spinal cord injuries in cats, showing reduced hindlimb reflex responses and altered coordination during locomotion.

This study investigates how forelimb movements affect hindlimb cutaneous reflexes during locomotion in cats, showing that forelimb movement influences the modulation of these reflexes, especially long-latency responses.

This study examines how spinal cord injuries affect cutaneous reflexes and interlimb coordination during locomotion in cats, finding reduced mid- and long-latency reflex responses correlate with impaired balance and coordination.

This study examines how adult cats negotiate obstacles after spinal cord injury, finding improved clearance over time with changes in muscle activation and weight distribution.

This study shows that perineal mechanical stimulation modulates spinal locomotor activity and reduces cutaneous reflexes in spinal cats, suggesting it excites central pattern-generating circuits rather than increasing reflex gain.
