Eight clinical normal subjects (two males aged between 30 and 45 years; six females aged between 18 and 65 years) were examined. Under the hypothesis that magneto-sensory evoked potentials are nonlinear, the brain electrical responses exhibited by human subjects would be expected to differ even when the exposures were replicated. Therefore, the participants were exposed at two times separated by at least one week and results compared in this regard.

Using recurrence analysis (nonlinear analysis), magneto-sensory evoked potentials were detected in each subject in both the initial and replicate studies, with one exception. All magneto-sensory evoked potentials exhibited characteristics, indicating that they were nonlinearly related to the magnetic field stimulus.
Using time averaging (linear analysis) the magneto-sensory evoked potentials were not detected, thereby further confirming their nonlinearity.
