Outline of Final Research Achievements

In the present study, we investigated motivational brain activities, which are reflected as SPN, using EEG and fMRI to verify effects of affective auditory stimulus. There were three experimental conditions: voice sound, melody sound, and beep sound. Purposes of the research were to describe cortical distributions of the SPN and to find the presence of a right hemisphere preponderance that could be caused by different auditory stimulus. Results revealed that there is less topographical distribution difference between the 3 auditory stimuli. The right hemisphere preponderance was found in the beep sound stimulus; moreover motivational score is lower then the voice and melody sound stimuli. The present results suggest that a certain types of auditory stimulus caused lower motivation. Furthermore, to find any cortical difference between voice stimulus and melody sound stimulus will be required.
