Skin–Nerve Preparation to Assay the Function of Opioid Receptors in Peripheral Endings of Sensory Neurons

This chapter describes the methodology of the in vitro skin–saphenous nerve preparation and its application to test for the modulatory effects of opioids on the function of cutaneous sensory neurons in experimental models of pain. We detail the skin–nerve setup requirements and the technique to record action potentials from single sensory fibers. We address how to test for inhibitory effects of opioid receptor activation on mechanical and thermal sensitivity of nociceptors and mechanoreceptors in the complete Freund’s adjuvant-induced inflammation and the chronic constriction injury model of neuropathic pain.
