Regulation of breathing
... Chemical regulation of respiration The activity of the respiratory centers is regulated by the O2, CO2 and H+ content of the blood. Carbon dioxide and H+ are most important. CO2 dissolves in cerebrospinal fluid (CSF) which bathes receptors sensitive to H+ on the ventral aspect of the medulla. Sti ...

Use of lipophilic dyes in studies of axonal pathfinding in vivo
