Induction of Neuropathic Pain in a Rat Model by Constriction of the Infraorbital Nerve

Induction of Neuropathic Pain in a Rat Model by Constriction of the Infraorbital Nerve

Source: Deseure, K., et al. Chronic Constriction Injury of the Rat's Infraorbital Nerve (IoN-CCI) to Study Trigeminal Neuropathic Pain. J. Vis. Exp. (2015).This video demonstrates a method to induce neuropathic pain in a rat model by constricting the infraorbital nerve. After exposing the infraorbital nerve and tying ligatures to constrict it, the immune response at the injury site increases the excitability of neighboring neurons, which transmit pain signals to the...

The Sciatic Nerve Cuffing Model of Neuropathic Pain in Mice

Neuropathic pain is a consequence of a lesion or disease affecting the somatosensory system. The “cuff model” of neuropathic pain in mice consists of the implantation of a polyethylene cuff around the main branch of the sciatic nerve. Mechanical allodynia is tested using von Frey...
