| Outline of Final Research Achievements |
We investigated the association between the density of histamine H3 receptor (H3R) and the cognitive function. Ten healthy male participants were recruited in this study. All participants performed fMRI and PET scans on the same day. The H3R density was measured by a new PET ligand. To reveal the neural basis of cognitive function, we measured the neural activity with fMRI during working memory task. An exploratory analysis using the data of H3R density obtained from PET study and the data of neural activity obtained from fMRI study revealed that the activity of prefrontal cortex during N-back task was associated with the H3R density of the same region.
