The central drive is exquisitely sensitive to<br />changes in CO2/H+ concentration. New data show that the fast- acting neurotransmitter acetylcholine is essential in the<br />CO2/H+ ventilatory response as well as in generating the central drive. Ret gene and MASH-1 are essential in<br />development of the parasympathetic system and thus in the central respiratory drive. Clinical states of hypoventilation<br />most likely have a genetic defect affecting the cholinergic system.This article will review briefly the site and mechanisms<br />of action of CO2 centrally, the neurotransmitters involved in the process, the gene(s) involved in the process and clinical<br />states where there are abnormalities in the system and inevitably hypoventilation results.<br />(Tanaffos 2002;1(1):9-13 ) https://www.tanaffosjournal.ir/article_241904_08ec61bbe9858011c4a0b4b91d6ace81.pdf
