The effect of increasing static magnetic field strength up to 4.7 Tesla on the electrical function of the cat brain was studied by EEG frequency analysis and recording of somatosensory evoked potentials. While the latencies of the peaks P6 and P10 of the somatosensory evoked potentials were stable during the time course of the experiment, EEG intensity, EEG frequency index and the P10/N15 amplitude showed substantial fluctuations. EEG intensity varied between 67 and 156%, and EEG frequency index between 65 and 140% of the mean value averaged over the whole length of the experiment. The P10/N15 amplitude even varied between 16 and 186% of the mean amplitude. Despite these variations none of the variables correlated with the strength of the magnetic field. The observed changes are therefore interpreted as spontaneous fluctuations of vigilance and not as effects of the static magnetic field.
通过脑电图（EEG）频率分析和体感诱发电位记录，研究了高达4.7特斯拉的静磁场强度增加对猫脑电功能的影响。在实验过程中，体感诱发电位的P6和P10峰潜伏期稳定，但脑电图强度、脑电图频率指数和P10/N15振幅出现了大幅波动。脑电图强度在整个实验长度的平均值的67%至156%之间变化，脑电图频率指数在平均值的65%至140%之间变化。P10/N15振幅甚至在平均振幅的16%至186%之间变化。尽管存在这些变化，但没有一个变量与磁场强度相关。因此，观察到的变化被解释为警觉性的自发波动，而不是静磁场的影响。
