Seventeen clinically normal subjects (eight men, nine women, age range: 18-51) took part in this study. Magneto-sensory evoked potentials were determined by using a) recurrence analysis (linear and nonlinear determinism) and b) time averaging method (only linear determinism). As a positive control, a binaural 424 Hz tone (sound pressure level: 65 dB) was presented.
Exposure duration: 2 s

Using the method of recurrence analysis, magneto-sensory evoked potentials in the signals from occipital derivations were found in 16 of the subjects. Magneto-sensory evoked potentials in the signals from the central and parietal electrodes were found in most subjects.
Using the method of time averaging, no magneto-sensory evoked potentials were detected in any brain region.
