Outline of Final Research Achievements

In the present study, not only FDG-PET but also MRI were used to measure morphological changes as well as metabolic changes to determine neurogenesis. Subjects were randomly assigned to blight light therapy and dim light therapy, both of which continued for 4 weeks. As a result, blight light therapy but not dim light therapy significantly increased volume and glucose uptake in the right olfactory bulb. The present findings suggest that bright light therapy for 4 weeks may induce neurogenesis in the right olfactory bulb.
