Pneumotaxic center

Pneumotaxic center is a part of the pons, an area of the brainstem, that plays a crucial role in the regulation of respiration. It is also known as the pontine respiratory group and is one of the several components of the respiratory centers of the brain.

Function

The pneumotaxic center controls both the intensity and frequency of breathing. It sends signals to the dorsal respiratory group (DRG) in the medulla oblongata, which in turn controls the rhythm of respiration. The pneumotaxic center inhibits the activity of the apneustic center, another part of the pons involved in respiration, to prevent over-inflation of the lungs.

Structure

The pneumotaxic center is located in the upper part of the pons, near the fourth ventricle. It consists of a network of neurons that generate impulses transmitted to other parts of the respiratory centers.

Clinical significance

Damage to the pneumotaxic center can lead to apneustic breathing, a condition characterized by prolonged inspiratory gasps interrupted by occasional expirations. This can be caused by stroke, brain injury, or neurodegenerative diseases.
