运动皮层的感觉运动表征是动态的、分布的和重叠的。这维持了在运动后或脑损伤后的整个生命中进行显著功能重组的能力，这在皮质可塑性中起着重要作用。研究表明，肢体损伤或面神经损伤会导致运动皮层的重组。对皮层可塑性的动物研究表明，在治疗性截肢的猴子中，面部表征占据了手部表征，而在面神经损伤的大鼠中，前肢表征占据了面部表征。此外，面神经麻痹的患者表现出扩大和侧向延伸的手运动区向面运动区。相反，面肌痉挛患者的同侧手表征面积相对于对侧减少，手表征的重心移向皮质面表征区域。因此，改变可塑性可能在功能恢复中起重要作用。
Sensorimotor representation in the motor cortex is dynamic, distributed and overlapping. This maintains the capacity for significant functional reorganization throughout life following exercise, or after brain injury, which plays an important role in cortical plasticity. It has been shown that injuries in limbs or facial nerve lesions cause reorganization in the motor cortex. Animal studies on cortical plasticity indicate that the face representation occupied the hand representation in monkeys with therapeutic amputations, and the forelimb representation occupied the face representation in rats with facial nerve lesions. Furthermore, patients with facial nerve palsy exhibited an expansion and lateral extension of the hand motor area toward the face motor area. On the contrary, patients with hemifacial spasm showed a decrease in the ipsilateral hand representation area relative to the contralateral side, and the center of gravity of the hand representation moved to the region of cortical face representation. Thus, altering plasticity may play an important role in the recovery of function.
