Two groups of eight adults successfully trained with biofeedback for increases in 40-Hz EEG responses in left or right hemispheres also demonstrated significant 40-Hz EEG increases during baseline periods, and increases in the contralateral hemisphere during training periods. No changes in heart rate, 40-Hz EMG, or 21- or 31-Hz beta, alpha, or theta EEG occurred over training days. Three subjects returning for additional training demonstrated suppression of 40-Hz EEG. A group of four subjects experiencing daily bidirectional training produced substantial within-session control of 40-Hz EEG but no changes over days. Data from posttraining tests without feedback for successful subjects in both groups indicated significant control of 40-Hz EEG responses in the initial parts of these sessions, and some correlated changes in other EEG responses. Measures of successful subjects' experiences during training and control tests indicated awareness of changes in subjective concomitants of EEG responses. This study suggests further strategies for research on behavioral correlates of EEG activity.
两组各八名成年人通过生物反馈训练成功提高了左半球或右半球的40赫兹脑电图反应，他们在基线期也表现出显著的40赫兹脑电图增加，在训练期对侧半球也有增加。在训练期间，心率、40赫兹肌电图或21或31赫兹的β、α或θ脑电图均无变化。三名回来接受额外训练的受试者表现出40赫兹脑电图受到抑制。一组四名每天进行双向训练的受试者在训练期间对40赫兹脑电图进行了有效的控制，但数天内没有变化。两组成功受试者在无反馈的训练后测试数据表明，在这些测试的初始阶段，40赫兹脑电图反应得到了显著控制，并且其他脑电图反应也有一些相关变化。成功受试者在训练和对照测试期间的体验测量表明，他们意识到了脑电图反应主观伴随物的变化。这项研究为脑电图活动行为相关性的研究提出了进一步的策略。
