Background & Objectives
Headache is a common symptom of post-concussion syndrome which may persist in a substantial portion of patients contributing to a poor quality of life and disability. There is a pressing need to develop novel treatments for post-traumatic headache as current treatments have a number of side effects, are contraindicated or lack efficacy. The Elliott laboratory first established models of post-traumatic headache demonstrating sensitization of trigeminal neurons in rodent models of post-traumatic headache using well-known nociceptive and behavioral markers in the pain and migraine fields1-3. Traumatic brain injury in mice increases expression of calcitonin gene related …

Abstract
The goal of this study was to investigate the role of the cannabinoid receptor type-2 (CB2R) in the trigeminal pain pathway in a model of post-concussion headache. Sprague Dawley rats were randomized to receive either a repeated mild closed head injury (CHI) or served as incision controls. Changes in CGRP, nNOS, and IBA-1 were assessed in the trigeminal nucleus caudalis (TNC) and trigeminal ganglia via IHC. A subset of CHI rats received either a cannabinoid receptor type 2 (CB2R) anti-inflammatory agonist (JWH133), an NSAID (Ketorolac), or vehicle and underwent von Frey testing for trigeminal allodynia. …

Introduction
Isometheptene is thought to be the active ingredient of the commonly known headache medication, Midrin. Previously, we found only the (R) enantiomer to be effective in alleviating headache behavior in two models of headache compared to the (S) enantiomer.
Experiments using electrical and mechanical stimulation of the dura in animals with no history of head pain have been used to elucidate the mechanisms of the trigeminovascular system at the level of the trigeminal ganglion, trigeminal nucleus caudalis, periaqueductal gray, and the thalamus. The limitation of these acute models is that electrical and mechanical stimulation of the dural blood vessels …
