Not to confuse with the public radio station, research at NPR is focused on the sensory encoding and processing of the peripheral nervous system. Particular interests are given on 1) how the sensory afferent neurons detect and transmit pain-related sensory information, 2) the peripheral mechanisms that underlie the sensory aberrations in chronic pain and 3) translating scientific discoveries into next-generation neuromodulatory strategies and devices that target peripheral nerves/neurons as non-drug alternatives for managing chronic pain.
One in every three adults in the USA suffers from at least one type of chronic pain (Portenoy, 2004). Pain clinicians will tell you that there are treatment options to mitigate most types of chronic pain, but not for visceral pain. Drugs that work for other types of pain are generally ineffective at managing visceral pain. Clinicians can quickly exhaust their means at treating patients with chronic visceral pain. Considering this unmet clinical need, NPR lab's top priority of study is chronic visceral pain, one of the most frequent reasons for patients to seek medical attention.
We employ a multi-disciplinary approach that includes 1) experimental studies on the sensory nerve endings by in vitro electrophysiology and biomechanics of visceral tissue, 2) state-of-the-art molecular biology and generic knock-out/knock-in mouse models, and 3) computational simulations and rigorous mathematical analysis that integrates the experimental findings to deepen the theoretical understanding of visceral afferent encoding and sensitization. As biomedical engineers, we are also enthusiastic in engineering the next generation tools for neuroscience studies in general and chronic pain management in particular.
