there is a set of receptors which are called piezo receptors, P-I-E-Z-O piezo receptors, piezo means pressure. And these were discovered a few years ago by a couple of different laboratories, but one of the main ones, one of the main laboratories that discovered these piezo receptors is the laboratory of Ardem Patapoutian. [...] The piezo receptors line many tissues, and inform the brain about pressure in those tissues. But the lungs have a particular category of piezo receptors called piezo two receptors. And as you fill your lungs and these little sacs of air, the alveoli fill, the piezo two receptors because of the way they react to that filling send information by way of a bunch of neurons, a bunch of wires up to the brain and tell you how full your lungs are
