Using structural MRI and whole-head EEG recordings, we analyzed the correlations between the anatomical parameters of the corpus callosum and the hemispheric distribution of the cortical movement-related potentials during right finger and shoulder movements in nine right-handed men. Statistically significant correlation was found only in finger movements. A relatively large genu and the anterior part of the truncus of the corpus callosum correlated with enhanced pre-movement EEG potential over the ipsilateral M1/S1 area. The lateralization of the movement-related potentials correlates with the size of those callosal regions which connect the homologous areas of the primary sensorimotor and frontal cortices.
我们使用结构磁共振成像（MRI）和全脑脑电图记录，分析了9名右利手男性在右手手指和肩部运动过程中胼胝体解剖参数与皮质运动相关电位半球分布之间的相关性。仅在手指运动中发现了具有统计学意义的相关性。胼胝体相对较大的膝部和干前部与同侧M1/S1区域运动前脑电图电位增强相关。运动相关电位的偏侧化与连接初级感觉运动皮层和额叶皮层同源区域的胼胝体区域大小相关。
