Implementing Microneurography
The technique of microneurography has been used in laboratory settings and in clinical trials to study autonomic nervous system function. Microneurography was originally used to investigate afferent discharges in myelinated fibers from the muscles and skin More current research is examining the action potentials in afferent and efferent C-fibers, unmyelinated peripheral axons. Experiments performed using microneurography have elucidated details of muscle sympathetic nerve activity (MSNA), skin sympathetic nerve activity (SSNA), the action of several classes of C-fibers including nociceptors (pain receptors), as well as pruritus (itching), abnormal blood pressure control, and thermoregulation.
