Abstract :
Evoked magnetic fields associated with the perception of visual apparent movement were measured with a multichannel DC SQUID. The sources of visual apparent movement were estimated as 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. This dipole model simulates well the evoked magnetic and electric fields associated with visual apparent movement
