Single-fiber recording is an effective electrophysiological technique that is applicable to the central and peripheral nervous systems. Along with the preparation of intact DRG with the attached sciatic nerve, the mechanism of conduction failure is examined. Both protocols improve the understanding of the peripheral nervous system's relationship with pain.

This protocol describes a straightforward method for creating coated filaments for the middle cerebral artery occlusion (MCAO) model in mice using silicone, nylon sutures, and syringe needles. This method allows for the production of filaments with a consistent diameter and various silicone wrapping lengths tailored to experimental needs.
