| Research Abstract |
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.
