title: Power increases within the gamma range over the frontal and occipital regions during acute exposures to cerebrally counterclockwise rotating magnetic fields with specific derivatives of change.
abstract: A total of 11 men and women were exposed for 5 min each to six different temporal configurations of pulsed magnetic fields that were delivered through serial activation of 8 solenoids in a counterclockwise direction around the head within the horizontal plane above the ears. Twenty-second samples of quantitative electroencephalographic activity within the delta, theta, lower alpha, upper alpha, beta, and gamma regions were collected after each configuration had been activated for 2.5 min. Only the circumcerebral presentation of the first pulse for 25 ms followed by an acceleration of +2 ms to each of the other 7 solenoids (the last duration = 11 ms) resulted in a significant increase in power within the gamma range (35 Hz to 45 Hz) over both frontal and occipital lobes but not over the parietal or temporal lobes. These results suggest topical application of specific spatial-temporal configurations of magnetic fields may affect the recursive creation of the rostral-caudal waves of cohesive fields that might produce consciousness.
