The examination of the human brain at a tissue, cellular, or molecular level is useful for understanding brain disease as well as for developing medicine and treatment options. It is important to study different brains when evaluating disease progression.

The Japan Brain Bank Network (JBBN) is a brain bank that can be used across Japan. It was established in 2016 by funding from the Strategic Research Program for Brain Science, Japan Agency for Medical Research and Development (AMED). The subject was the “Integrative Research on Depression, Dementia and Development disorders (IR3D)”.

Eight major brain banks in Japan have joined the JBBN and share their database of brain stocks, and co-operate with the wider brain bank project.
The JBBN collects brain tissue from various neurological and psychiatric diseases as well as from healthy controls that have donated. The brains are diagnosed neuropathologically and stored for biomedical research use upon request.
