Abstract
One of the areas that stand out in the ventilatory response to CO2 is the A6 region or Locus coeruleus (LC), where more than 80% of noradrenergic neurons are sensitive to CO2/pH. During the development of rodents, the chemosensitivity of LC neurons is intermittent, being more sensitive in newborn rats younger than 10 days (<P10) and less sensitive in rats older than 10 days (>P10).
