Welcome to the Department of Neural and Pain Sciences

The Department of Neural and Pain Sciences (NPS) is a Department of the University of Maryland School of Dentistry with research, teaching, and service responsibilities. Its research and educational domains are in the area of neuroscience, with a strong emphasis on the neurobiology of pain. NPS faculty members conduct multidisciplinary sensory-motor system research with a major focus on acute and chronic pain mechanisms. Leaders in this department use state-of-the-art methods including advanced molecular, neurophysiological, neuroanatomical, and neuroimaging techniques. As part of the school of dentistry, this department has a special interest in pain and dysfunction that manifests itself in the orofacial complex. However, we also recognize that study of somatic and visceral pain models throughout the body will provide scientific advances that can benefit our understanding of orofacial pain conditions.

A majority of the faculty conduct preclinical research. At the same time, the department also recognizes the need to transfer its groundbreaking basic science research into the clinical setting, in order to better manage clinical conditions, especially chronic pain, and improve quality of life. As such, collaborative research with clinicians in the school of dentistry, school of medicine, and elsewhere is an important part of our departmental mission. The science conducted by this department is integrated into the graduate and post-graduate programs of the school of dentistry and the Graduate Program in Life Sciences (GPILS) through faculty driven curricular innovations and dedicated teaching efforts.

Dr. Man-Kyo Chung received NIDCR Award for Sustaining Outstanding Achievement in Research (SOAR) (R35) entitled “Trigeminal Nociceptors: Neural Intersection of Chronic Pain and Alveolar Bone Remodeling”. In this project, dual roles of trigeminal sensory afferents on two fundamental areas in oral health. This award supports total $8M for 8 years.

Ke Ren, Ph.D./Feng Wei, Ph.D. - R01 DE029946 (Ren/Wei, MPI) NIH/NIDCR 07/01/2020-6/30/2025 Amount:  $3,030,104 (Total direct and indirect) Amount:  $3,030,104 (Total direct and indirect) "Disruption of Homeostatic Neuroimmune Interactions in Descending Circuitry in the Development of Pain Chronicity” Project summary:  Millions of people suffer from chronic or persistent pain, which is a major medical problem.  The current treatment for chronic pain conditions is unsatisfactory.  In recent years, ample evidence has documented the role of glia and their interactions with neurons in the development of persistent pain.  Despite overwhelming evidence from preclinical studies, clinical trials for the treatment of chronic pain with glial modulators have not been successful, which is related to our incomplete understanding of the mechanisms.  While a majority of studies show the pain-facilitating aspect of the injury-related glial activity, a potential inhibitory/protective role of neuron-glial interactions in the development of persistent pain has been largely overlooked.  This project will analyze inhibitory/beneficial neuroglial interactions in the descending pain modulatory circuitry and test the hypothesis that disrupted inhibitory glial activity contributes to the emergence of chronic pain.  Exploring the beneficial effect of glial activity will fill the gap in our understanding and lead to a transformative shift in the search for improved management for chronic pain.
