We investigated the electrical activity of the occipital, sensorimotor, and frontal zones in the right and left hemispheres of the cerebral cortex and times for bimanual motor response in healthy adult experimental subjects between the ages of 15 and 25 receiving photostimulation by means of pulse trains with frequencies increasing from 15 to 25 Hz and pulse trains with frequencies decreasing from 15 to 5 Hz. We observed nonspecific physiological reactions in the organism regardless of the type of photostimulation presented and also observed specific reactions dictated by the parameters of the light stimulus acting upon the brain. It was demonstrated that the action of the light was most effective when the frequency of the stimuli was gradually increased. The expressiveness of the alpha-band of oscillations in the electrical brain activity increased in this case, and the asymmetry of the bimanual motor responses changed significantly. A definite connection was noted between the physiological reactions of the experimental subjects and their subjective states.
我们研究了年龄在15至25岁之间的健康成年实验对象，在接受频率从15赫兹增加到25赫兹的脉冲序列以及频率从15赫兹降低到5赫兹的脉冲序列进行光刺激时，大脑皮层左右半球枕叶、感觉运动区和额叶的电活动以及双手运动反应的时间。无论呈现何种类型的光刺激，我们都观察到机体出现非特异性生理反应，同时也观察到由作用于大脑的光刺激参数所决定的特异性反应。结果表明，当刺激频率逐渐增加时，光的作用最为有效。在这种情况下，脑电活动中α波段振荡的表现力增强，双手运动反应的不对称性也发生了显著变化。实验对象的生理反应与其主观状态之间存在一定的关联。
