Research
Dr. Mizuno's laboratory studies autonomic control of the cardiovascular system, focusing on the mechanisms underlying alterations in circulatory control in type1 or type2 diabetes and Alzheimer’s disease. More specifically, the lab is actively investigating the central and peripheral mechanisms underpinning the abnormal alterations in sympathetic nerve activity that accompany the pathogenesis of these diseases.
