This study examined the effects of the relaxation response, elicited by autogenic training, on central nervous system (CNS) activity. We used computerized spectral analysis of EEG activity as a dependent measure. After baseline EEG data were obtained for all subjects, the experimental group practiced standard autogenic exercises for 15 experimental sessions with home practice. The control subjects received the same number of sessions under identical conditions, except that they listened to a pleasant radio show without home practice. Subjects were then posttested to assess the acute and chronic effects of autogenic training and the relaxation response on CNS activity. The results indicated significant acute effects differences between groups; the experimental group showed greater increases in theta and greater decreases in alpha percent total power. The results suggest that the relaxation response elicited by autogenic training produces significant acute changes in EEG activity and a characteristic spectral pattern; the results also suggest that focusing attention on a repetitive, internal stimulus is a key element in Benson's relaxation response model.
本研究考察了由自生训练引发的放松反应对中枢神经系统（CNS）活动的影响。我们将脑电图（EEG）活动的计算机化频谱分析作为一项因变量指标。在获取了所有受试者的脑电图基线数据后，实验组进行了15次标准自生训练练习，并要求在家中进行练习。对照组在相同条件下接受相同次数的训练，只是他们听了一档轻松的广播节目，且没有在家中练习。然后对受试者进行后测，以评估自生训练和放松反应对中枢神经系统活动的急性和慢性影响。结果表明两组之间存在显著的急性效应差异；实验组在θ波方面有更大幅度的增加，在α波总功率百分比方面有更大幅度的下降。结果表明，自生训练引发的放松反应会使脑电图活动产生显著的急性变化以及一种特征性的频谱模式；结果还表明，将注意力集中在重复性的内部刺激上是本森放松反应模型的一个关键要素。
