Studies on 33 anesthetized white mice were used to determine the motor representation of facial muscles and limb muscles by an intracortical microstimulation method. Microstimulation produced predominantly ipsilateral movement responses of facial muscles and contralateral responses in fore- and hindlimb muscles. Low-threshold stimulation in the left and right hemispheres showed a clear asymmetry of the motor representation of the facial muscles. Movement responses of the hindlimbs were obtained on microstimulation of the frontal regions of the neocortex, demonstrating the existence of multiple motor representations of muscles in the neocortex.
对33只麻醉的小白鼠进行研究，采用皮质内微刺激法来确定面部肌肉和肢体肌肉的运动代表区。微刺激主要产生面部肌肉的同侧运动反应以及前肢和后肢肌肉的对侧反应。左右半球的低阈值刺激显示出面部肌肉运动代表区明显不对称。在新皮质额叶区域进行微刺激时可获得后肢的运动反应，这表明新皮质中存在肌肉的多个运动代表区。
