| Outline of Final Research Achievements |
Alexithymia is an important psychopathology which manifests inability to identify self’s emotion and difficulty in expressing it. The aim of this study is to reveal neural basis of the relationship between body and mind status changes, using functional magnetic resonance imaging (fMRI). For self-continuity based on autobiographical information, we created web system to record everyday events and found that positive memories are more retained than negative ones, which involves hippocampus activities. We also measured brain activity with fMRI and concurrently heart rate variability (HRV) in response to emotional stimuli, and found insula and ventromedical prefrontal activity and connectivity were correlated with parasympathetic factor in HRV. Oversensitivity to interoceptive information increased anxiety and insula activity was decreased in alexithymia.
