Saad Nagi is an associate professor in neurophysiology at Linköping University, Sweden. His laboratory’s interests revolve around understanding the peripheral nervous system’s role in acute and persistent pain using microneurography (single-unit afferent recordings in awake humans) combined with targeted pharmacological and psychophysical approaches. A recent focus area is understanding how the nervous system creates and modulates perceptions linked to the activation of very fast-conducting myelinated nociceptors in health and disease.
