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.

We present a protocol to assess changes in neuromuscular function. Percutaneous electrical nerve stimulation is a non-invasive method that evokes muscular responses. Electrophysiological and mechanical properties of these responses permit the evaluation of neuromuscular function from brain to muscle (supra-spinal, spinal and peripheral levels).
FAQs
Nerve root stimulation changes the membrane potential of excitable axons, which can initiate or modify action-potential transmission. Because axons differ in their functional roles, the resulting signal may recruit sensory or motor fibers and alter how information travels through connected spinal circuits. This membrane-level effect links an applied electrical input with downstream neural communication.
Recruiting sensory or motor fibers engages different parts of neural function. Sensory-fiber activation can influence signaling related to sensation and pain pathways, whereas motor-fiber recruitment can affect circuits involved in motor control. Distinguishing these responses helps researchers interpret which neural pathways are being influenced and supports more precise functional mapping.
Electrical impulses can change action-potential transmission in axons connected to spinal circuits. Those altered signals can influence synaptic activity, the communication process between connected neural cells, and neurotransmitter release. In biochemical research, this connection allows investigators to examine how changes in electrical signaling affect cellular communication rather than studying neurotransmitter processes in isolation.
Functional mapping primarily uses changes produced by stimulation to investigate nerve function and identify how spinal pathways participate in sensory or motor processes. Therapeutic neuromodulation instead focuses on altering neural signaling in a useful way, including effects on pain pathways. The same underlying electrical influence can therefore support either experimental analysis or intervention.
A basic assessment applies controlled electrical impulses to a spinal nerve root and examines how neural signaling changes in response. Investigators can relate the stimulation to recruitment of sensory or motor fibers, action-potential transmission, and activity in connected spinal circuits. This approach provides a structured way to evaluate nerve function and signaling pathways.
Nerve root stimulation supports physiological research, functional mapping, and investigations of sensory processing and motor control. It can also help examine pain pathways by showing how electrical changes affect connected spinal signaling. In biochemistry and neurobiology, the method connects cellular communication, action-potential activity, synaptic processes, and neurotransmitter release within a common experimental framework.
