To assess the relationship between hemispheric differences in information processing and interhemispheric asymmetries in terms of brain bioelectrical activity, we correlated scores on the MMPI Depression scale with interhemispheric asymmetry, measured as peak amplitude and latency of the P3 component of somatosensory evoked potentials (SEPs) at the frontocortical region of 14 healthy unselected volunteers (8 men and 6 women) who were about to start a course in autogenic training. The sample was subdivided into two groups on the basis of the median score on the MMPI Depression scale. Subjects scoring above the median showed a right lateralization at the frontocentral region and a significantly shorter P3 latency at the right hemisphere compared to the left.
为了评估信息处理中的半球差异与基于脑生物电活动的半球间不对称性之间的关系，我们将明尼苏达多相人格调查表（MMPI）抑郁量表得分与半球间不对称性进行了关联分析。半球间不对称性通过14名即将开始自生训练课程的健康非特定志愿者（8名男性和6名女性）额叶皮质区域体感诱发电位（SEP）的P3成分的峰值幅度和潜伏期来衡量。根据MMPI抑郁量表的中位数得分，将样本分为两组。得分高于中位数的受试者在额中央区域表现出右侧化，并且与左侧相比，右侧半球的P3潜伏期明显更短。
