Source: Jakobs, M., et al. Subcutaneous Trigeminal Nerve Field Stimulation for Refractory Facial Pain. J. Vis. Exp. (2017)This procedure demonstrates the implantation of subcutaneous electrodes for trigeminal nerve stimulation to treat neuropathic facial pain. The electrodes are tunneled subcutaneously from the affected facial region to an infraclavicular pocket, where they are connected to an internal pulse generator (IPG). The IPG delivers electrical stimulation, activating mechanoreceptor...

Treating chronic or neuropathic facial pain can be challenging when medical or standard treatment fails. Subcutaneous nerve field stimulation is the least invasive form of neuromodulation and is used for chronic back pain. We applied this technology to treat chronic and neuropathic trigeminal facial pain.

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Implantation of an Electrode Assembly in a Mouse Brain for Electrophysiological Recording

This video demonstrates a technique for implanting an electrode assembly into a mouse brain. The assembly contains bipolar electrodes to record activity from the hippocampus and a reference electrode to obtain baseline activity from the cerebellum. An anesthetized mouse is placed on a stereotaxic frame, and the electrode assembly is implanted in the target brain region. The animal is then allowed to recover before performing electrophysiological recording.

This protocol describes how to generate carbon fiber electrodes. The electrodes are subsequently used to detect catecholamine release from vesicles with carbon fiber amperometry.
FAQs
These electrodes detect voltage changes generated by nearby nerves or muscles through a conductive interface positioned beneath the skin. Their location gives electronic equipment access to biological signals without relying solely on measurements at the body surface. In neuroscience, this arrangement supports monitoring of neural and peripheral physiological activity during studies of nerve function.
Recording uses the electrode to sense naturally generated voltage changes, whereas stimulation uses externally controlled electrical pulses to activate excitable tissue. The same general interface can therefore support either observation or intervention, depending on how it connects to the controlling equipment. This distinction allows researchers to study nerve responses as well as evaluate electrically driven bioelectronic therapies.
Placement beneath the skin can provide more direct access to nearby nerves or muscles than surface electrodes, which may improve access to the electrical activity generated by those tissues. This positioning is especially relevant when researchers need to monitor peripheral physiological signals or examine nerve function through a closer interface with the target tissue.
Their small size and minimally invasive placement can support long-term recordings while limiting the physical burden of the interface. This combination is useful when researchers need to follow neural or peripheral physiological activity over extended periods rather than collect only a brief measurement. It also contributes to the development of emerging neural interfaces.
Researchers can use these electrodes to monitor voltage changes associated with nearby nerves and muscles, along with other peripheral physiological signals. The resulting measurements help investigate nerve function and provide information about electrical activity in tissues outside the central nervous system. Their use therefore connects neural measurement with broader studies of peripheral physiology.
In therapy-oriented research, subcutaneous electrodes can deliver controlled electrical pulses to excitable tissue, allowing investigators to examine the effects of targeted activation. They may also provide an interface for monitoring activity during such studies. This combined potential for stimulation and recording makes them relevant to evaluating bioelectronic therapies and developing neural-interface approaches.
