We recorded cortical magnetic fields following voluntary and passive movements. The most prominent movement-evoked magnetic field (MEF1) following active movement was obtained approximately 35.3 ms after movement onset, and the equivalent current dipole (ECD) was estimated to be in the primary motor cortex (Brodmann area 4). Two peaks of MEG response associated with passive movement were recorded from 30 to 100 ms after movement onset. The earliest component (PM1) peaked at 36.2 ms, and the second component (PM2) peaked at 86.1 ms after movement onset. The peak latency and ECD localization of PM1, estimated to be in area 4, were the same as those of the most prominent movement-evoked magnetic field following active movement. ECDs of PM2 were estimated to be not only in area 4 but also in the supplementary motor area (SMA) and the posterior parietal cortex (PPC) over the hemisphere contralateral to the movement, and in the secondary somatosensory cortex (S2) of both hemispheres.

我们记录了自愿和被动运动后的皮质磁场。最突出的运动诱发的磁场（MEF 1）后，主动运动获得约35.3 ms后，运动发作，和等效电流偶极子（ECD）估计是在初级运动皮层（布罗德曼区4）。在运动开始后30 ~ 100 ms记录到两个与被动运动相关的MEG反应峰。运动开始后，最早的成分（PM 1）在36.2 ms达到峰值，第二成分（PM 2）在86.1 ms达到峰值。PM 1的峰值潜伏期和ECD定位，估计是在4区，是相同的最突出的运动诱发磁场后主动运动。PM2的ECDs估计不仅在4区，而且在补充运动区（SMA）和后顶叶皮层（PPC）的运动对侧的半球，并在次级躯体感觉皮层（S2）的两个半球。
