FHC microneurography electrodes (referred to as needles by many) were developed to record multi-unit peripheral nerve activity. The tip taper is dramatically shorter and broader than our standard microelectrodes and convex to facilitate a minimally painful penetration through the skin.
These tungsten electrodes can be provided with a variety of shank diameters and impedances to satisfy various recording requirements. A number of termination options are available to aid in the placement and support of the electrode in the nerve.
They are also typically provided with a 15mm square manipulating tab to aid in accurate placement. Alternatively, an insulated floating termination can be provided to allow the electrode to move with the target tissue. Our microneurography electrodes are available in an uninsulated configuration as well for use as a reference electrode.
