| Outline of Final Research Achievements |
Deterioration of intracerebral networks occurs in aging and neuropsychiatric disorders, and "myelination tuning" by oligodendrocytes has been found to be important. However, evaluation of brain ultrastructural changes is difficult to observe with conventional MRI, and analysis of "myelination tuning" is limited. The applicants aimed to contribute to the development of new diagnostic markers for neuropsychiatric disorders in the future, in comparison with histological data obtained by observing ultrastructural changes in ultra-high resolution and three-dimensional images.
