We have conducted MEG (magnetoencephalography) measurements while normal subjects were watching a set of selected pictures for which affection values were established. During the measurement, either flicker-light stimulation at the frame of pictures or repetitive sound stimuli was delivered to the subjects at a stimulation rate that (or its harmonic) was matched to the frequency of visual or auditory rhythmic activity. Results of the steady state response indicated augmentation of the response-amplitude for negative than positive affective pictures. We suggest that the rhythmic neural activities could serve as objective measures of internal condition such as affection or cognitive load.

我们进行了MEG（脑磁图）测量，而正常受试者正在观看一组选定的图片，情感值建立。在测量过程中，无论是在帧的图片或重复的声音刺激的闪烁光刺激提供给受试者的刺激率（或其谐波）是匹配的频率的视觉或听觉的节奏活动。稳态反应的结果表明，负性情感图片的反应幅度比正性情感图片大。我们认为节律性神经活动可以作为情感或认知负荷等内部条件的客观测量。
