Effects of sensory awareness, imagery and observation on electroencephalography in adult with psychological stress

Abstract

[Purpose] The aim of the present study was to examine the effects of brain activation using sensory awareness, imagery, and observation in adults with psychological stress. [Participants and Methods] The participants of the study were 30 adults with psychological stress. They responded to questionnaires, including a stress response inventory. Data for brain activation were collected for sensory awareness, imagery, and observation using electroencephalography. To determine the neurological changes in the brain, this study analysed the relative power of sensory motor rhythm of the participants using electroencephalography. [Results] Results showed that the relative power of the sensory motor rhythm was significantly greater during awareness and imagery of sensory than during observation. [Conclusion] The results of this study suggest that awareness, imagery, and observation of sensation should be considered as useful modalities in people with psychological stress.
