| Research Abstract |
The purpose of this research was to quantify brain functions related to children's mental stability.
Mental status was measured by using fill-able psychological tests, and brain function and autonomic nervous function are measured by using electroencephalography (EEG), magnetoencephalography (MEG) and electrocardiography (ECG). Time-frequency analysis was adopted to process those data.
As a result the reactions of brain functions were classified on the basis of the mental stability. The temporal activities under unpleasure stimuli in the mental unstable group are significantly larger than those in the mental stable group. The frontal activities under pleasure stimuli in the mental stable group tend to be larger than those in the mental unstable group. Moreover, occipital activities after visual and auditory stimuli in the mental stable group are larger than those in the mental unstable group. These results suggest that the brain functional processes of the mental unstable people would be different from those of the mental stable people.
We also investigated qualification of the brain function related to image capability, stress, or trauma. These results would help that any kinds of mental problems could be qualified as brain's reactions.
