Trigeminal afferences implied in the triggering or inhibition of sneezing in cats

The aim of this study was to precise the role of the different trigeminal nerve branches involved in innervation of the nostril in triggering the sneeze reflex. Electrical stimulation of the anterior ethmoidal, posterior nasal and infraorbital nerves was performed in anaesthetized cats. Stimulation...

Summary:The aim of this study was to precise the role of the different trigeminal nerve branches involved in innervation of the nostril in triggering the sneeze reflex. Electrical stimulation of the anterior ethmoidal, posterior nasal and infraorbital nerves was performed in anaesthetized cats. Stimulation of these 3 nerves produced sneezing identical to that induced by mechanical stimulation. Our results emphasize inhibition of the sneeze reflex related to stimulation of the anterior ethmoidal or the posterior nasal nerves by stimulation of the infraorbital nerve.
