WebEarly inspiratory neurons trigger the augmenting discharge of inspiratory neurons. This increase in activity, which produces lung expansion, is caused by self-excitation of the … WebRespiration is controlled by a section of the brain called the medulla. Lying on either side of the medulla are chemoreceptors that sense changes in the level of pCO2 in the blood. When the level of pCO2 becomes too high or too low, chemoreceptors send signals to the inspiratory center within the medulla to increase breathing or slow it. ipart fire and rescue
