Cortex-dependent recovery of unassisted hindlimb locomotion after complete spinal cord injury in adult rats.

abstract：:miR-128, a brain-enriched microRNA, has been implicated in the control of neurogenesis and synaptogenesis but its potential roles in intervening processes have not been addressed. We show that post-transcriptional mechanisms restrict miR-128 accumulation to post-mitotic neurons during mouse corticogenesis and in adult...
