Twenty-four right-handed patients undergoing primal therapy served as subjects in the study. They all showed symptoms of tension, anxiety, and/or depression. The patients' right and left temporal EEGs were recorded immediately before and after a therapy session. Recordings were done while the patients were resting, and while they were performing a verbal and a visual task with their eyes closed. The EEG data were analysed off-line with a computer, using quantitative amplitude analysis in the 1.5 to 30 Hz frequency band. A "high intensity" group (n = 13) having high ratings of emotional activity in their therapy session was compared with a "low intensity" group (n = 11) with low ratings. The results showed that only in the "high intensity" group was there a significant increase in mean amplitude and amplitude variance in the right hemisphere, measured across conditions. A between-group comparison revealed that the "high intensity" group showed a significantly larger increase in right hemisphere variance and in right over left variance ratio, relative to the "low intensity" group, in which these variables were almost unchanged. These results indicate a greater involvement of the right hemisphere in emotional activity. It is also suggested that the EEG changes found in the "high intensity" group, following a therapy session, reflect a general deactivation of the brain and a functional improvement of the right hemisphere.
24名接受原始疗法的右利手患者作为研究对象。他们均表现出紧张、焦虑和/或抑郁症状。在一次治疗前后即刻记录患者的右侧和左侧颞叶脑电图。记录是在患者休息时以及闭眼执行言语和视觉任务时进行的。脑电图数据在离线状态下用计算机进行分析，采用1.5至30赫兹频段的定量幅度分析。将在治疗过程中情绪活动评分高的“高强度”组（n = 13）与评分低的“低强度”组（n = 11）进行比较。结果显示，仅在“高强度”组中，跨条件测量时右半球的平均幅度和幅度方差有显著增加。组间比较显示，相对于“低强度”组，“高强度”组右半球方差以及右/左方差比的增加显著更大，而在“低强度”组中这些变量几乎没有变化。这些结果表明右半球在情绪活动中参与度更高。还表明在“高强度”组中治疗后发现的脑电图变化反映了大脑的整体失活以及右半球的功能改善。
