title: Upper airway and abdominal motor output during sneezing: is the in vivo decererate rat an adequate model?
abstract: While numerous studies have focused on identifying and characterizing the neural mechanisms mediating upper airway defense reflexes in the anesthetized or decerebrate adult cat, little is known about these behaviors in in vivo rodent models. The current study was undertaken to investigate whether the in vivo decelerate adult rat might serve as an acceptable model for studying these behaviors. To begin to address this possibility, we examined multiple respiratory motor activities in response to mechanical stimulation of the anterior nasal cavity (sufficient to elicit fictive sneezing) in in vivo decerebrate adult rats. We found that the neural activities observed during nasal stimulation were consistent with those previously reported during fictive sneezing in the adult cat model. We suggest that the in vivo decerebrate rat is an acceptable model for studying the sneezing reflex.
