Abstract
In severe hypoxia, homeostatic mechanisms maintain function of the brainstem respiratory network. We hypothesized that hypoxia involves a transition from neuronal mechanisms of normal breathing (eupnea) to a rudimentary pattern of inspiratory movements (gasping). We provide evidence for hypoxia-driven transformation within the central respiratory oscillator, in which gasping relies on persistent sodium current, whereas eupnea does not depend on this cellular mechanism.
