Abstract

Adrenaline regulates respiratory network, however, adrenergic contribution to the developing respiratory center has not well studied. Adrenaline application on embryonic day 17 medulla–spinal cord block preparations abolished non-respiratory activity and enhanced respiratory frequency. Phentolamine application on neonatal brainstem-spinal cord preparations that produced stable neonatal respiration resulted in respiratory destabilization. In E19 rat, adrenaline switched from enhancement to depression of the respiratory rhythm. Adrenaline modulated GABAergic synaptic transmission to respiratory neurons in late developmental stage. These results suggest that the involvement of central adrenergic modulation on the respiratory network maturation.
