Main Interests

Our laboratory is interested in pain and inflammation. We study the properties of sensory afferents (nociceptors) that transduce the mechanical, thermal and chemical events that are perceived as painful. Afferent cell bodies are isolated from sensory ganglia of rats and placed in a small petri dish. Small glass electrodes fuse with the cell body and enable us to study the currents induced by pro-inflammatory agents. These agents both activate nociceptors and induce plastic changes that are important in inflammatory pain. We examine the specific influences of agents on different classes of nociceptors and how each may influence nociceptor plasticity.
