Shifts in the Plutchik emotion profile indices following three weekly treatments with pulsed vs continuous cerebral magnetic fields.
Compared to baseline measures, the emotional profile indices of normal volunteers who received 3 weekly exposures to 20 min. of bilateral burst-firing magnetic fields along the temporal plane displayed increased aggression and decreased trust relative to those exposed to pulsed (1 sec. every 4 sec.) fields or to control conditions. The effect size was equivalent to an eta of 0.70. There were no shifts in Holtzman Inkblot Projection Scores. These results suggest that brief cerebral exposures to weak magnetic fields that simulate the burst-firing of amygdaloid cells may affect specific limbic emotions.
