| Research Abstract |
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.
