This study investigate the mutual fine-tuning of ongoing EEG rhythmic features with RGB values controlling color shades of computer screen during neuro-feedback training. Fifteen participants had not been informed about the existence of neurofeedback loop (NF), but were guided only to look at the computer screen. It was found that during such unconscious NF training, a variety of color shades on the screen gradually changed from rather various types to the main one within the framework of color palette specified for each individual. This phenomenon was not observed in control experiments with simulated neuro-feedback. Individual color patterns induced on the screen during NF did not depend on the schema of connection between of EEG rhythms and RGB controller. It is suggested that the basic neurophysiological mechanism of described NF training consists of the directed selection of EEG patterns reinforced by comfortable color shades without conscious control.
本研究调查了在神经反馈训练期间，正在进行的脑电图节律特征与控制电脑屏幕颜色深浅的RGB值之间的相互微调。15名参与者此前未被告知神经反馈回路（NF）的存在，仅被引导注视电脑屏幕。研究发现，在这种无意识的NF训练过程中，屏幕上的各种颜色深浅在为每个个体指定的调色板框架内，逐渐从相当多样的类型转变为主要类型。在模拟神经反馈的对照实验中未观察到这种现象。NF期间在屏幕上诱发的个体颜色模式并不取决于脑电图节律与RGB控制器之间的连接模式。研究表明，所描述的NF训练的基本神经生理机制包括在无有意识控制的情况下，通过舒适的颜色深浅对脑电图模式进行定向选择。
