Microneurography as a tool to study the function of individual C-fiber afferents in humans: responses from nociceptors, thermoreceptors, and mechanoreceptors

Journal of Neurophysiology, 2018
International audienceThe technique of microneurography—recording neural traffic from nerves in awake humans—has provided us with unrivaled insights into afferent and efferent processes in the peripheral nervous system for over 50 years.

The use of real-time ultrasound in microneurography [PDF]

Autonomic Neuroscience: Basic and Clinical, 2011
The use of microneurography to measure muscle sympathetic nerve activity has provided important insights in human physiology. However, placing microelectrodes into nerves can be challenging, particularly in certain patient populations. In this paper, we describe the use of real-time ultrasound guidance to assist with microneurography, including ...

Skin biopsy and microneurography disclose selective noradrenergic dysfunction due to dopamine-β-hydroxylase deficiency

Autonomic Neuroscience: Basic and Clinical, 2016
Skin biopsy and microneurography are autonomic tests directly evaluating adrenergic and cholinergic sympathetic fibers to identify selective deficiency of a specific peripheral sympathetic subdivision.

Microneurography, impulse conduction, and paresthesias†

Muscle and Nerve, 1993
AbstractIt is possible to learn more about peripheral nerve function in human subjects than is obtainable with routine nerve conduction studies, and thereby to study the basis of “positive” symptoms, such as paresthesias. Using microneurography, ectopic impulse activity in cutaneous afferents has been recorded in patients suffering from neurologic ...

The methodology and scope of human microneurography

Journal of Neuroscience Methods, 1997
Microneurography was introduced in 1967 and has developed into an invaluable tool for investigating human somatosensory, motor and cardiovascular physiology and pathophysiology. It involves percutaneous insertion of a metal microelectrode into fascicles of limb and facial nerves.

Assessing static and dynamic sympathetic transduction using microneurography

Journal of Applied Physiology, 2021
The relationship between sympathetic nerve activity and the vasculature has been of great interest due to its potential role in various cardiovascular-related diseases. This relationship, termed “sympathetic transduction,” has been quantified using several different laboratory and analytical techniques.

Microneurography

Journal of Cardiovascular Pharmacology, 1985
Alpha-2 receptor agonists may act to decrease sympathetic influences through central neural actions that inhibit sympathetic outflow and peripheral adrenergic effects that inhibit release of norepinephrine. Direct intraneural recordings using microneurography of postganglionic sympathetic nerve activity in humans permit assessment of effects of alpha-2

Microneurography for the recording and selective stimulation of afferents: An assessment

Muscle & Nerve, 1988
AbstractThe purpose of this study was to examine whether a microneurography electrode could record from and then selectively stimulate the same afferent fiber in cat sural and tibial nerves. Fiber activity was recorded distally with microneurography needle electrodes and proximally with hook electrodes.

After-Effect of Microneurography in Humans

Physical Therapy, 1981
Twenty subjects were followed up to three months after microneurographic recording of sympathetic nerve fiber activity to determine the nature and incidence of sequelae to the invasive microneurographic procedure. Skin or muscle parethesias lasting two weeks on the average were reported by the majority of subjects.

Chapter 29 Microneurography in the assessment of neuropathic pain

2006
Publisher Summary This chapter describes microneurography as a neurophysiological method that allows microelectrode recordings of impulses in single nerve fibers in awake human subjects. It has been employed for recordings from afferent sensory nerve fibers, efferent sympathetic nerve fibers, and proprioceptive nerve fibers.
