Abstract
Breathing is our first act upon birth and the last action we complete before death. The first to last breath taken, is in fact, how we define someone’s life. Since it was first reported that the blood concentration of CO2istightly controlled, and provides the dominant drive to breathe, the search for the cells that regulate it began. It took almost 60 years for the identification of the first central chemosensitive areas, regions within the brain that respond to specific chemical stimuli (such as CO2or its proxy H+), found at the ventrolateral surface of the medulla (VLM). Since then the debate over which cells in these areas are responsible for detectingCO2and signalling its fluctuations to the respiratory oscillators, has been extensive and heated. Chemosensitive cells are thought to have cell bodies located in, or close to, the VLM with dendrites in close apposition to blood vessels to better detect changes in blood gases. Several candidates fulfil this criteria, including the retrotrapezoid nucleus (RTN) and medullary raphe.
