Journal of Neurochemistry, Volume 170, Issue 2, February 2026.The ventral root avulsion (VRA) model provides an excellent experimental paradigm for studying injuries at the Central/Peripheral Nervous Systems (CNS/PNS) interface. By physically disconnecting motoneurons (MNs) from the spinal cord surface, VRA induces profound cellular, molecular, and functional deficits with limited spontaneous recovery.
