Cortical reorganization occurs within the primary somatosensory and the primary motor cortex after amputation of the arm or forearm. Here we report on a patient showing cortical reorganization after amputation of his right index finger. Our findings indicate that the neural networks within the area of the amputated finger in the somatosensory cortex (SI) were invaded by neighbouring structures, i.e. of neural cell assemblies that subserve the thumb and middle finger of his right hand.
在手臂或前臂截肢后，初级体感皮层和初级运动皮层会发生皮质重组。在此，我们报告一名右手食指截肢后出现皮质重组的患者。我们的研究结果表明，体感皮层（SI）中被截肢手指区域内的神经网络被相邻结构侵入，即服务于其右手拇指和中指的神经细胞集合。
