A team of researchers have discovered a signaling system within the brainstem that activates almost immediately at birth to support early breathing. That first gasp that every parent cherishes appears to trigger this support system.
“Birth is traumatic for the newborn, as the baby has to independently take control over various important body functions, including breathing,” said Bayliss, chairman of UVA’s Department of Pharmacology. “We think that activation of this support system at birth provides an extra safety factor for this critical period.”
