誘発脳波・脳磁図による仮現運動の電源推定

抄録

Apparent movement is the experience of motion that occurs when at least two spatially separated stimuli are delivered sequentially under appropriate temporal conditions. In the present study, we measured and analyzed visual evoked electric and magnetic fields to localize the electric brain sources associated with the perception of apparent movement. Evoked magnetic fields associated with the perception of visual apparent movement were measured with a multi channel dc SQUID. The sources of visual apparent movement were estimated at at least three current dipoles. Two dipoles were located in the bilateral middle temporal area, and the third dipole was estimated in the occipital visual area.
