The paper shows that two coupled oscillators with a delayed, odd-phase interaction implement a proportional-derivative control law near synchrony, with gains determined by coupling function slope and delay.

The paper shows that spinal cord activity in macaques lacks rotational dynamics during an alternating isometric task, unlike motor cortex activity.

This study uses a neuromuscular model to show that spinal reflex gain adaptations, not belt speed changes, drive gait asymmetry during split-belt treadmill locomotion.

This study uses computer simulations to investigate whether gait training in spinalized rats leads to stable spinal circuitry recovery, finding that both stabilizing and destabilizing learning strategies result in functional recovery but not necessarily stable circuitry.
