Magnetic responses in representative subjects. a Stimulus. b magnetic waveforms in pair gradiometers with the greatest response, and root mean square (RSS) signals of pair gradiometers in a representative subject. Responses to the upper, lower, and full-field stimulations are shown. Note that responses to the lower and upper visual field stimulations were opposite in polarity and that the response to the full-field stimulation was approximately the sum of the two. c RSS waveforms for four refractive states obtained from selected pair gradiometers in two subjects
