There are defined medullary, mesencephalic, hypothalamic, and thalamic functions in regulation of respiration, but knowledge of cortical control and the elements subserving the consciousness of breathlessness and air hunger is limited. In nine young adults, air hunger was produced acutely by CO(2) inhalation. Comparisons were made with inhalation of a N(2)/O(2) gas mixture with the same apparatus, and also with paced breathing, and with eyes closed rest. A network of activations in pons… CONTINUE READING
