Ventilatory Complexity Persists in Phox2b Mutant Mice Lacking the Retrotrapezoid Nucleus/Parafacial Respiratory Group (RTN/pFRG) and in Humans With Congenital Central Hypoventilation Syndrome.

Abstract excerpt

Breathing is inherently variable due to the nonlinear dynamics of its brainstem neural control. In amphibians, a gill and a lung oscillator interact to produce breathing but the lung oscillator is necessary and sufficient to produce a mathematically complex behavior. In mammals, where the preBötzinger complex (preBötC) is considered homologous to the amphibian lung oscillator and the retrotrapezoid...
