Summated evoked potentials to peroneal nerve stimulation which arise in the cauda equina and spinal cord afferent pathways were recorded from surface electrodes placed over the spine of 95 infants, children and adults. The conduction velocity of these potentials from lumbar to cervical recording sites was calculated. Additionally, segmental conduction velocities over peroneal nerve, caudal and rostral spinal cord were determined. In all age groups the speed of conduction up the spine was non-linear. It was slower over caudal spinal cord segments than over peripheral nerve or rostral cord. All these velocities were about half adult values in the newborn and progressively increased with age. The conduction velocity over peripheral nerve was within the adult range by 3 years of age. The speed of conduction over the spinal cord did not reach adult values until the 5th year. This suggests that spinal cord afferent pathways mature at a slower rate than peripheral nerve fibers.
通过置于95名婴儿、儿童及成人脊柱上的表面电极，记录了由马尾和脊髓传入通路产生的腓总神经刺激的总和诱发电位。计算了这些电位从腰部记录部位到颈部记录部位的传导速度。此外，还测定了腓总神经、尾侧和头侧脊髓的节段传导速度。在所有年龄组中，沿脊柱向上的传导速度都是非线性的。尾侧脊髓节段的传导速度比周围神经或头侧脊髓的传导速度慢。所有这些速度在新生儿中约为成人值的一半，并随年龄逐渐增加。周围神经的传导速度在3岁时达到成人范围。脊髓的传导速度直到5岁才达到成人值。这表明脊髓传入通路的成熟速度比周围神经纤维慢。
