Changes in EEG fine structure in the occipital areas, heart rate, and breath pattern were recorded in 10 male volunteers under photic stimulation with slowly varying frequency in the range of lower or higher EEG alpha-subbands. Self-ratings (on the scale SAN-self-assessment of state of health, activity, and mood) of the functional state, general activity, and mood were obtained before and after stimulation. EEG effects of such photostimulation were represented by the resonance EEG responses of discrete spectral EEG components, frequencies of which periodically coincided with varying rate of flashes. Resonance alpha-enhancement levels depended on the initial individual EEG alpha-voltage and stimulation frequency. Average changes in objective and subjective parameters did not differ between the conditions of lower and higher frequencies of stimulation but were significantly different and of opposite signs when the subjects gave higher and lower self-ratings of positive stimulation effect regardless of the stimulation frequency.
在10名男性志愿者中，记录了在脑电图（EEG）α子带较低或较高频率范围内频率缓慢变化的光刺激下，枕叶区域的EEG精细结构、心率和呼吸模式的变化。在刺激前后，获得了功能状态、总体活动和情绪的自我评分（采用健康、活动和情绪状态自我评估量表）。这种光刺激的EEG效应由离散频谱EEG成分的共振EEG反应表示，其频率与闪烁变化率周期性一致。共振α增强水平取决于个体初始EEGα电压和刺激频率。在较低和较高刺激频率条件下，客观和主观参数的平均变化没有差异，但当受试者对正向刺激效果给出较高和较低自我评分时，无论刺激频率如何，这些变化都存在显著差异且符号相反。
