The Spared Nerve Injury animal model is described here as a mouse model of peripheral neuropathic pain following partial denervation of the sciatic nerve by lesioning the tibial and common peroneal nerve branches, leaving the remaining sural nerve intact. Behavioral modification resulting from mechanical allodynia is quantified by von Frey filaments.

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.

2025
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...
FAQs
Its typical formation from the medial sural cutaneous branch of the tibial nerve and a communicating branch of the common fibular nerve creates a sensory pathway assembled from two peripheral contributions. This arrangement helps explain why the nerve carries information from a continuous posterolateral lower-limb region and provides an anatomical basis for evaluating distal sensory function.
The nerve’s accessible course along the calf and toward the foot makes it practical to examine outside the central nervous system. Because it is purely sensory, measurements from it can focus on sensory pathway abnormalities without needing to interpret motor output. This supports neuroscience studies of peripheral nerve function and clinically oriented investigations of sensory impairment.
Sural nerve measurements can help distinguish patterns associated with axonal injury, demyelination, or nerve regeneration. These categories describe different effects on peripheral nerve integrity and recovery, so the findings can contribute to characterizing how a sensory pathway has been damaged or is changing over time. Interpretation is therefore relevant to both neuropathy assessment and regeneration research.
Sensory nerve-conduction studies use the sural nerve as an accessible peripheral sensory pathway for functional evaluation. Measurements obtained from the nerve can support assessment of peripheral neuropathy and help characterize abnormalities affecting sensory transmission. In neuroscience, this makes the technique useful for linking an observable conduction result with broader patterns of peripheral nerve dysfunction.
A sural nerve biopsy may be used when direct examination of peripheral nerve tissue is needed in research or clinical investigation. Its accessible location supports sampling, while the resulting tissue can contribute to studies of nerve pathology and structural change. Because biopsy is an invasive procedure, its role differs from noninvasive functional measurement through sensory nerve-conduction studies.
The sural nerve is relevant to grafting procedures and to research on peripheral nerve regeneration because it can be accessed along the lower limb and provides a sensory nerve pathway for examination. Measurements and tissue-based observations can be considered together: functional data indicate changes in nerve performance, while biopsy or grafting contexts address structural or restorative investigation.
