My research focuses on developing novel functional imaging techniques to understand cerebral energy metabolism and hemodynamics due to neuronal activation. In addition, using a novel functional techniques, I am trying to understand the neuronal processing of olfaction and taste in the human and animal brain.

Functional magnetic resonance imaging (fMRI) based on the blood oxygenation level-dependent (BOLD) effect is a powerful tool for brain functional mapping since it non-invasively provides high spatial and temporal resolution. Since fMRI obtains signal changes related to changes in cerebral metabolism and hemodynamics, fMRI indirectly measures neuronal activity during functional activation. Therefore, it is important to understand the mechanisms of neuro-vascular-metabolic coupling under both functional activation and resting conditions.

Currently, I am using fMRI and developing novel techniques at 7T field strengths to understand the relationship between neuronal activity and hemodynamic-metabolic changes. This research aims to improve the spatiotemporal resolution of fMRI, and includes development of calibrated BOLD and direct measurement of neuronal activity.

In addition, I am applying novel imaging and fMRI at 7T to functionally and anatomically understand how the brain processes olfaction and taste.
