Dr. Zixi Jack Cheng's lab at the University of Central Florida focuses on the sensory systems of the heart, particularly how nerves from the vagus and spinal cords communicate about heart health and disease. They examine both healthy and diabetic hearts to understand how these nerve systems change and affect heart function. By mapping these nerves in rats and humans using advanced imaging techniques, the lab aims to create detailed 3D models that can guide new treatments for heart-related conditions, especially in diabetic patients.
