Breathing automatically is controlled by respiratory centers in the brainstem. The medulla oblongata provides the main rhythmic generator for respiration, with groups that drive inspiration and expiration. The dorsal respiratory group mainly handles inspiration, integrating input from chemoreceptors, while the ventral respiratory group contributes to expiration and active breathing. The pons modulates the rhythm and depth of breathing, smoothing the transitions between inspiration and expiration. Together, these brainstem regions set the involuntary breathing pattern you maintain without thinking about it. Higher brain areas like the hypothalamus, cerebellum, or thalamus are not the primary generators of this rhythm, though they can influence breathing under certain conditions.
