The axonal sprouting that occurs after denervation resulting from a spinal hemisection can be quantified. Rats were subjected to hemisection of the spinal cord at birth, and the myelinated and unmyelinated axons in dorsal roots three segments cranial and three segments caudal to the lesion were counted 1 month after surgery. The number of unmyelinated axons in the dorsal root on the side of the hemisection increased 22 percent for the roots one segment from the lesion and 13 percent for the roots two and three segments from the lesion.
脊髓半切术后去神经支配所发生的轴突发芽可以被量化。在出生时对大鼠进行脊髓半切手术，术后1个月对损伤部位头侧和尾侧三个节段的背根中髓鞘化和无髓鞘化的轴突进行计数。在半切侧，距离损伤部位一个节段的背根中无髓鞘化轴突数量增加了22%，距离损伤部位两个和三个节段的背根中无髓鞘化轴突数量增加了13%。
