Spinal microcircuits for motor learning
Neural circuits for learning movement are distributed in the nervous system. Given that following spinal cord injury, locomotor training can lead to significant improvement in gait, and given the importance to learning of neural circuits that compute sensory prediction error, we asked whether such learning circuits are present in the spinal cord. I will discuss one such spinal microcircuit, and demonstrate its necessity for motor learning. Understanding mechanisms of spinal plasticity is important for the further development of strategies aimed at improving motor function following injuries to or diseases of the nervous system.
