WebIn- fants have an active Hering–Breuer reflex that decreases with age but is still present during early childhood (26). Clinically, this can be a problem for children receiving continuous posi- tive airway pressure (CPAP), who sometimes develop central apnea during positive pressure application (27). WebDec 7, 2009 · This study describes a novel phenomenon which consists of alterations in the Hering-Breuer reflexes in response to electrical microstimulation applied to sites in the prefrontal cortex. This fact suggests that the prefrontal cortex is able to modulate respiratory reflexes evoked by SARs. grandview bank cleburne tx routing number
