Pneumotaxic center
The pneumotaxic center, also known as the pontine respiratory group (PRG), is a network of neurons in the rostral dorsal lateral pons. It consists of the Kölliker-Fuse nucleus and the medial parabrachial nucleus. It is considered an antagonist to the apneustic center, which produces abnormal breathing during inhalation.
Respiratory effects
The PRG antagonizes the apneustic center, cyclically inhibiting inhalation. The PRG limits the burst of action potentials in the phrenic nerve, effectively decreasing the tidal volume and regulating the respiratory rate. Absence of the PRG results in an increase in depth of respiration and a decrease in respiratory rate.

Medullary Respiratory Center: Control of Breathing (DRGs vs. VRGs)
What is the Medullary Respiratory Center? This video covers the medical definition and provides a brief overview of this topic. 💥Respiratory Therapy Definitions [Glossary] ➜ ➜ ➜ https://bit.ly/3g6s4Pj ➡️ Dorsal Respiratory Groups The dorsal respiratory groups (DRGs) are neurons located in the posterior region of the medulla. They are responsible for assimilating various factors that influence breathing, such as peripheral stretch receptors in the lungs, central chemoreceptors, and peripheral chemoreceptors. DRGs relay information to VRGs, which are responsible for controlling the rate, rhythm, and depth of breathing. ➡️ Ventral Respiratory Groups Ventral respiratory groups (VRGs) are complex neurons that run bilaterally between the brain stem and the pons-medulla junction. These neurons ...

Voice by: Ashley Fleming
Receptors in the body feed information about its metabolic state to the respiratory center in the brainstem, which responds by changing the firing pattern of inspiratory and expiratory neurons. The fibers of these neurons descend to the cervical and thoracic spine where they synapse with motor neurons. Motor neurons then travel in several nerves to respiratory muscles, changing the way these muscles contract, adjusting thereby the rate and depth of breathing to suit the body’s needs. Of most importance are phrenic nerves which control the diaphragm, and intercostal nerves which innervate intercostal muscles. The respiratory center is composed of several areas in the medulla: the dorsal respiratory group, DRG, mainly associated with inspiration; the ventral respiratory group, VRG, mostly concerned with expiration; and the pre-Bötzinger complex, possibly coupled with two other oscillators, thought to be the intrinsic rhythm generator, similar to the pacemaker in the heart. The medullar areas also communicate with two other areas in the pons to fine-tune the respiration control: the pneumotaxic center which seems to inhibit inspiration, while the apneustic center stimulates it.
The most important factor regulating breathing rate is the concentration of carbon dioxide. Changes in carbon dioxide leads to changes in pH, and these are detected by chemoreceptors. Central chemoreceptors located on the surface of the medulla monitor pH changes in the cerebrospinal fluid; while peripheral chemoreceptors found in the aortic and carotid bodies respond to fluctuations in pH, carbon dioxide, as well as oxygen levels in the blood. Peripheral receptors transmit signal to the respiratory center via the vagus and glossopharyngeal nerves. The respiratory center also receives input from various mechanoreceptors in the lungs, which transmit information about the mechanical status of the lungs via the vagus nerve.Pulmonary stretch receptors present in smooth muscle of the airways are activated when the lungs are excessively inflated, and trigger the inflation reflex. Other receptors respond to inhaled irritants and are responsible for defensive respiratory reflexes such as bronchoconstriction or coughing. The limbic system and hypothalamus also send information to the respiratory center and allow pain and emotional state to affect breathing. Voluntary control is also possible, for example, during singing, playing wind instruments, or holding breath under water. In this case the control originates from the primary motor cortex, which sends signals directly to the spinal cord, bypassing the respiratory center in the brainstem.

💥Respiratory Therapy Definitions [Glossary] ➜ ➜ ➜ https://bit.ly/3g6s4Pj
➡️ Dorsal Respiratory Groups
The dorsal respiratory groups (DRGs) are neurons located in the posterior region of the medulla. They are responsible for assimilating various factors that influence breathing, such as peripheral stretch receptors in the lungs, central chemoreceptors, and peripheral chemoreceptors. DRGs relay information to VRGs, which are responsible for controlling the rate, rhythm, and depth of breathing.
➡️ Ventral Respiratory Groups
Ventral respiratory groups (VRGs) are complex neurons that run bilaterally between the brain stem and the pons-medulla junction. These neurons fire during both inspiration and expiration, making them essential for breathing to occur. During inspiration, neurons are stimulated and send impulses along the phrenic and intercostal nerves. This causes the diaphragm and external intercostal muscles to contract, resulting in thoracic expansion, where air can flow into the lungs. During expiration, neurons are stimulated, and the inspiratory muscles relax, resulting in passive expiration. This breathing cycle repeats continuously to produce a normal respiratory rate of around 12–20 breaths/min.
➡️ Recap
VRGs are also responsible for gasping, which is an abnormal breathing pattern seen in patients with severe hypoxemia. If the VRG neurons are suppressed, it results in apnea or the complete stoppage of breathing. For example, this can occur in patients who have overdosed. DRGs are responsible for gathering information and relaying it to VRGs. The VRG neurons are responsible for triggering inspiration, and they also control the rate, depth, and rhythm of breathing.

Receptors in the body feed information about its metabolic state to the respiratory center in the brainstem, which responds by changing the firing pattern of inspiratory and expiratory neurons. The fibers of these neurons descend to the cervical and thoracic spine where they synapse with motor neurons. Motor neurons then travel in several nerves to respiratory muscles, changing the way these muscles contract, adjusting thereby the rate and depth of breathing to suit the body’s needs. Of most importance are phrenic nerves which control the diaphragm, and intercostal nerves which innervate intercostal muscles. The respiratory center is composed of several areas in the medulla: the dorsal respiratory group, DRG, mainly associated with inspiration; the ventral respiratory group, VRG, mostly concerned with expiration; and the pre-Bötzinger complex, possibly coupled with two other oscillators, thought to be the intrinsic rhythm generator, similar to the pacemaker in the heart. The medullar areas also communicate with two other areas in the pons to fine-tune the respiration control: the pneumotaxic center which seems to inhibit inspiration, while the apneustic center stimulates it.
The most important factor regulating breathing rate is the concentration of carbon dioxide. Changes in carbon dioxide leads to changes in pH, and these are detected by chemoreceptors. Central chemoreceptors located on the surface of the medulla monitor pH changes in the cerebrospinal fluid; while peripheral chemoreceptors found in the aortic and carotid bodies respond to fluctuations in pH, carbon dioxide, as well as oxygen levels in the blood. Peripheral receptors transmit signal to the respiratory center via the vagus and glossopharyngeal nerves. The respiratory center also receives input from various mechanoreceptors in the lungs, which transmit information about the mechanical status of the lungs via the vagus nerve.Pulmonary stretch receptors present in smooth muscle of the airways are activated when the lungs are excessively inflated, and trigger the inflation reflex. Other receptors respond to inhaled irritants and are responsible for defensive respiratory reflexes such as bronchoconstriction or coughing. The limbic system and hypothalamus also send information to the respiratory center and allow pain and emotional state to affect breathing. Voluntary control is also possible, for example, during singing, playing wind instruments, or holding breath under water. In this case the control originates from the primary motor cortex, which sends signals directly to the spinal cord, bypassing the respiratory center in the brainstem.

Pneumotaxic center
The pneumotaxic center, also known as the pontine respiratory group (PRG), is a network of neurons in the rostral dorsal lateral pons. It consists of the Kölliker-Fuse nucleus and the medial parabrachial nucleus. It is considered an antagonist to the apneustic center, which produces abnormal breathing during inhalation.
Respiratory effects
The PRG antagonizes the apneustic center, cyclically inhibiting inhalation. The PRG limits the burst of action potentials in the phrenic nerve, effectively decreasing the tidal volume and regulating the respiratory rate. Absence of the PRG results in an increase in depth of respiration and a decrease in respiratory rate.
