| Research Abstract |
In this study, neural basis of internet addiction was ionvestigated using molecular neuroimaging technique in healthy individuals. More precisely, the the relationship between scores of a questionnaire for internet use and dopamine D2 receptor binding potential (BP) was investigated considering the effect of psychological measures such as self-esteem. The number of the participants was 18 at the end of the project,that has not reached 20 (expected at the begging of the project). The experiment would be expected to be completed by the end of 2014.
The preliminary result suggested that scores of a questionnaire for internet use was negatively correlated with dopamine D2 receptor binding potential. The mediation effect of psychological measures was not significant.
