To address this gap, we recently devised a mouse model of trigeminal neuropathic pain, using a partial ligation of infraorbital nerve (pIONL) that induces allodynic response to tactile stimuli within the area innervated by infraorbital nerve (ION), with substantial changes in glial proliferation and neuropeptide expression in the trigeminal ganglion and caudal medulla [ 2 ].
