Time course and specificity of sensory-motor alpha modulation during the observation of hand motor acts and gestures: a high density EEG study.

abstract：:The relationship between phantom limb phenomena and cortical reorganization was examined in five subjects with congenital absence of an upper limb and nine traumatic amputees. Neuromagnetic source imaging revealed minimal reorganization of primary somatosensory cortex in the congenital amputees (M=0.69 cm, SD 0.24) an...
