Source: Svientek, S. R., et al. Fabrication of the Composite Regenerative Peripheral Nerve Interface (C-RPNI) in the Adult Rat. J. Vis. Exp. (2020).This video demonstrates the surgical construction of a composite regenerative peripheral nerve interface (C-RPNI) in a rat model of peripheral nerve injury. The procedure involves attaching a transected peroneal nerve to a muscle graft and overlaying it with a dermal skin graft to promote nerve regeneration. Over time, motor and sensory neurons...

Source: Sanchez, C. A., et al. Preparation of Peripheral Nerve Stimulation Electrodes for Chronic Implantation in Rats. J. Vis. Exp. (2020).This video demonstrates vagus nerve stimulation in an awake rat. A rat with an implanted chronic peripheral nerve cuff electrode and trained in a lever press task is connected to a stimulus generator via an implanted head cap. The vagus nerve is stimulated immediately after each successful lever press, resulting in the expansion of the motor map.

In this video, we demonstrate the biomechanical testing of the brachial plexus nerve in a pig model to measure the threshold tensile strength of the nerve when subjected to stretching. This technique helps in determining the structural and mechanical properties of the nerve.
FAQs
Spontaneous recordings capture electrical activity that occurs without deliberate stimulation, whereas evoked responses follow controlled electrical or sensory input. Comparing these signal types gives clinicians complementary information: spontaneous activity can reveal ongoing neural changes, while evoked responses show how effectively a pathway reacts to stimulation. Together, they support continuous assessment during procedures involving vulnerable neural structures.
Sensor location determines which aspect of nervous system function is being sampled. Sensors may be placed on the skin, muscles, or near nerves, allowing recordings from different points along a neural pathway. This positioning helps clinicians assess signal transmission and relate observed changes to particular structures during medical procedures or neurological evaluation.
Changes in recorded electrical activity provide objective information while a procedure is underway. When measurements suggest altered signal transmission, the clinical team can recognize a possible threat to neural function and consider how the intervention should proceed. This real-time feedback is especially relevant when surgery involves the brain, spine, thyroid, or peripheral nerves.
Controlled electrical or sensory stimulation creates a defined input against which nervous system responses can be measured. The resulting signals indicate whether transmission produces an observable response at the recording site. Because the stimulus is deliberate and repeatable in principle, it complements spontaneous activity and helps clinicians evaluate functional pathways during monitoring.
A monitoring workflow places appropriate sensors, records ongoing electrical activity, and may deliver controlled electrical or sensory stimulation. The system then captures spontaneous signals or evoked responses as the procedure progresses. Clinicians review these measurements in real time to identify changes, communicate potential concerns, and use objective information when making procedural decisions.
Its medical relevance is greatest in procedures where neural structures may be exposed to risk. The overview identifies operations involving the brain, spine, thyroid, and peripheral nerves as important settings. In these contexts, monitoring can help identify neural structures, alert the team to potential injury, and support efforts to preserve function during the intervention.
Nerve monitoring can also provide objective information for diagnosing or managing neurological disorders, not only for guiding surgery. Electrical recordings and responses to stimulation offer measurable evidence about nervous system function and signal transmission. This information can complement clinical assessment by documenting functional changes relevant to neurological evaluation and ongoing medical management.
