The percutaneous stimulation of both the motor cortex and the spinal cord have been used to study the central motor pathways of 19 healthy full-term newborns and of 5 infants (17 months to 4 years). The responses of lower limb muscles to cortical stimulation were more difficult to obtain than those of upper limb muscles. Conduction velocities of central motor fibres along the spinal cord (between C7 to L4) were around 10 m/s in full-term newborns and 38 m/s at the age of 4 years old. These values are considerably less than those published in adult man (48 to 60 m/s).
经皮刺激运动皮层和脊髓已被用于研究19名健康足月新生儿和5名婴儿（17个月至4岁）的中枢运动通路。下肢肌肉对皮层刺激的反应比上肢肌肉更难获得。足月新生儿沿脊髓（C7至L4）的中枢运动纤维传导速度约为10米/秒，4岁时为38米/秒。这些数值远低于成年男性公布的数值（48至60米/秒）。
