In a surprise discovery, researchers found that young rats recover more quickly from spinal cord injuries due to the activation of specialized neural stem cells and oligodendrocytes, which provide a protective myelin sheath to axons. This process does not occur as efficiently in adult rats, leading to longer recovery times.
