Investigating Mechanisms In Nociceptors Driving Ongoing Activity And Ongoing Pain, Elia Lopez
Dissertations & Theses (Open Access)
Ongoing (apparently spontaneous) pain at rest is a major complaint of patients suffering from many forms of acute and chronic pain, including acute and persistent postsurgical pain. Accumulating evidence suggests ongoing activity in nociceptors is a major driver of ongoing pain. Ongoing activity can be generated in sensory neurons in the absence of sensory generator potentials if one or more of three neurophysiological alterations occur – prolonged depolarization of resting membrane potential (RMP), hyperpolarization of action potential (AP) threshold, and/or increased amplitude of depolarizing spontaneous fluctuations of membrane potential (DSFs) to bridge the gap between RMP and AP threshold.
