Microneurography

Microneurography (pronunciation: /ˌmaɪkroʊnʊˈrɒɡrəfi/) is a technique used in neuroscience to record electrical activity from individual nerve fibers within a nerve bundle.

Etymology

The term "Microneurography" is derived from the Greek words "micros" meaning small, "neuron" meaning nerve, and "graphy" meaning to write or record.

Procedure

Microneurography involves the insertion of a fine electrode into a nerve, often in the leg or arm, to record the electrical activity of the nerve fibers. This technique allows for the direct measurement of action potentials in the peripheral nerves, providing valuable information about the function of the nervous system.

Applications

Microneurography has been used in a variety of research and clinical settings. It is particularly useful in studying the function of the autonomic nervous system, and has been used to investigate conditions such as hypertension, heart failure, and diabetes.
