    Lab Name: Neurovascular Coupling Laboratory



    Our laboratory aims to understand the basic mechanism of physiological interaction among neurons, glias and vascular system and provide better insights for perfusion related neuroimaging techniques. Our particular research interests include: 1) Study the effect of chronic stress on neurovascular coupling at functional and structural level, 2) Study  the effect of pathologically heightened neuronal excitation and synchronization on neurovascular coupling at functional and structural level and develop cell-therapy for epilepsy, 3) Study neurovascular coupling mechanism through neurovascular coupling modulators, such as nitric oxide, carbon monoxide, & glucose, and 4) Develop novel techniques to restore neurovascular coupling dysfunction

    We are always open to new possibilities for MR technical development and application to basic sciences as well as preclinical/clinical studies. We have recently been working on ultrashort echo-time (UTE) imaging with radial sampling and ultrafast imaging using spatiotemporal encoding. Among various UTE applications, we are now interested in its use in fMRI as well as lung imaging. Regarding ultrafast imaging, we recently developed a 3D gradient-echo-based ultrafast imaging technique using spatiotemporal encoding and are trying to find interesting applications (e.g. in fMRI).

    Modern high-field MRI provides unparalleled sensitivity and quantification accuracy for measurement of physical properties and processes of a living human body. In brain imaging, diffusion weighted imaging and quantitative susceptibility mapping are already widely used to map and measure water diffusion constant and magnetic susceptibility of grey and white matter, with a prospect of applying them as a quantitative biomarker for disease diagnosis. Our laboratory is interested in developing new methodologies for MRI to advance the magnetic resonance-based in-vivo physical property measurement and mapping. A strong emphasis is placed on solid understanding of the physics of MRI hardware and contrast generation, and translation of the research outcomes to clinical practices applied to local population.
