Previous research has shown that exposure to circumcerebral weak magnetic fields with different rates of acceleration applied in a counterclockwise rotation around the head was associated with increased estimations of subjective time and as much as a 30% increase in power within the theta range within quantitative electroencephalographic (QEEG) recordings. The largest effect was associated with magnetic fields applied with 20 ms rates of change through each of the successively stimulated, equally spaced, 8 circumcerebral solenoids. The purpose of the present study was to compare the intracerebral power spectra associated with the rotation of the same patterns in either the clockwise or counterclockwise direction. The results generally replicated previous reports and showed enhanced power over regions of the left hemisphere during clockwise rotations and over the right hemisphere during counterclockwise rotations. These results were considered congruent with the creation of "interference patterns" between the rostral-caudal generation of endogenous cerebral magnetic fields putatively associated with consciousness and the spatial direction of the applied rotating magnetic fields.
先前的研究表明，头部周围逆时针旋转施加不同加速度的大脑周围弱磁场，与主观时间估计增加以及定量脑电图（QEEG）记录中θ范围内功率增加多达30%有关。最大的效应与通过连续刺激的、等间距的8个大脑周围螺线管以20毫秒的变化率施加的磁场有关。本研究的目的是比较顺时针或逆时针方向旋转相同模式时相关的脑内功率谱。结果总体上重复了先前的报告，显示顺时针旋转时左半球区域功率增强，逆时针旋转时右半球区域功率增强。这些结果被认为与假定与意识相关的内源性脑磁场的头-尾生成与所施加旋转磁场的空间方向之间产生的“干涉模式”一致。
