This study was a preliminary evaluation of biofeedback training of human subjects to control high-frequency EEG responses in the 35- to 45-Hz (40-Hz) and 21- to 31-Hz ranges. A total of 22 adult males divided into three groups were successfully trained for increases or suppression of 40-Hz EEG, or increases of 21- to 31-Hz EEG. Dissociation of rates of 40-Hz EEG recorded from scalp leads and 40-Hz EMG responses from prominent muscle contaminators, and partial dissociation of 40-Hz and 21- to 31-Hz EEG responses were noted. After biofeedback training, 8 subjects demonstrated increase and suppression of 40-Hz EEG without feedback. No consistent descriptors of subjective experiences accompanying EEG changes were reported by subjects in any of the groups. The study suggests the utility of biofeedback procedures in research on high-frequency EEG activity.
本研究是对人类受试者进行生物反馈训练以控制35至45赫兹（40赫兹）和21至31赫兹范围内高频脑电图反应的初步评估。总共22名成年男性被分为三组，成功接受了增加或抑制40赫兹脑电图，或增加21至31赫兹脑电图的训练。记录到头皮导联的40赫兹脑电图速率与来自主要肌肉干扰源的40赫兹肌电图反应之间的分离，以及40赫兹和21至31赫兹脑电图反应的部分分离。生物反馈训练后，8名受试者在无反馈情况下表现出40赫兹脑电图的增加和抑制。任何一组受试者均未报告伴随脑电图变化的主观体验的一致描述。该研究表明生物反馈程序在高频脑电图活动研究中的效用。
