In this study, the individually determined upper alpha frequency band in EEG (electroencephalogram) was investigated as a neurofeedback parameter. Fourteen subjects were trained on five sessions within 1 week by means of feedback dependent on the current upper alpha amplitude. On the first and fifth session, cognitive ability was tested by a mental rotation test. As a result, eleven of the fourteen subjects showed significant training success. Individually determined upper alpha was increased independently of other frequency bands. The enhancement of cognitive performance was significantly larger for the neurofeedback group than for a control group who did not receive feedback. Thus, enhanced cognitive control went along with an increased upper alpha amplitude that was found in the neurofeedback group only.
在这项研究中，我们将个体确定的脑电图（EEG）中的上阿尔法频段作为神经反馈参数进行了研究。14 名受试者在一周内进行了 5 次训练，每次训练都根据当前的上阿尔法波幅进行反馈。在第一次和第五次训练中，我们通过心理旋转测试来测试认知能力。结果表明，14 名受试者中有 11 名表现出显著的训练效果。个体确定的上阿尔法频段独立于其他频段而增加。与未接受反馈的对照组相比，神经反馈组的认知表现提高更为显著。因此，认知控制的增强伴随着上阿尔法频段的增加，而这种增加仅在神经反馈组中出现。
