| Outline of Final Research Achievements |
To identify abnormal neural patterns related to the experience of a major depressive episode, we performed functional magnetic resonance imaging (fMRI) experiments using cognitive tasks in participants with depression and remission in depression. The patients with major depressive disorder showed specific brain activity during recall of happy/negative memories, compared to the healthy participants. Furthermore, the patients who had experienced multiple episodes showed distinctive functional connectivity patterns in (a) the cluster related to self/executive function and (b) the cluster related to the emotional system, compared to the patients who had experienced a single episode.
