Magnetic responses of the brain to rhythmic visual stimulation are measured at frequencies of ~10 Hz using a 7-channel SQUID magnetoencephalograph. Despite the stationarity of the stimulation, the responses of the brain demonstrate the constant instability of the amplitude and spatial distribution of the magnetic field. The signal from the eyes is periodically redirected to different parts of the cortex, although the stimulation is always the same.
