Seiji is particularly renowned for his pioneering contributions to functional magnetic resonance imaging (fMRI). He played a foundational role in developing the blood oxygenation level-dependent (BOLD) contrast technique, which forms the basis of modern fMRI. While he did not invent MRI technology itself—a process based on principles developed in the 1970s—his research significantly advanced the field by enabling the real-time visualization of brain activity.
This BOLD technique relies on detecting changes in blood oxygenation levels in the brain, providing insights into neural function and mapping physiological processes. Today, both MRI and fMRI are indispensable tools in fields such as neurobiology, neurology, biology, psychology, and medicine, widely used for diagnostic and research purposes.
Seiji is known to have been married, but he has consistently kept his personal life private. His reserved nature, coupled with limited media interest in academic figures, has resulted in minimal public information regarding his family or personal relationships.
Although specific details about Seiji’s annual salary or net worth are not publicly disclosed, it is generally believed that his decades-long career in research and academia, along with his leadership roles, account for a substantial income. His work is widely documented in scientific archives and is also summarized in his biography, available on platforms such as Wikipedia.
