Support Unit for Functional Magnetic Resonance Imaging

Equipped with a 4-Tesla MRI system, this unit supports non-invasive functional MRI (fMRI) studies on human subjects conducted by laboratories within BSI. The subjects participated in fMRI studies are limited to healthy adults of 20 years and older. Each experiment is conducted within 2 hours, including the preparation time. In order to use the MRI system, the head of laboratory intending to use the MRI facility should submit the experimental proposal and obtain the permission in advance from the RIKEN fMRI Safety and Ethics Committee.
