Pontine respiratory‐modulated activity before and after vagotomy in decerebrate cats
TLDR
It is concluded that DL pontine neurones receive both vagal‐dependent excitatory inputs and central respiratory drive, and even though changes in pontine activity are transient, they can persist after no‐I tests whether or not changes in the respiratory pattern occur in the subsequent cycles.
Pontine mechanisms of respiratory control.
TLDR
This review focuses on the pontine-mediated inspiratory off-switch (IOS) associated with postinspiratory glottal constriction, which is examined in the context of pontine regulation ofglottal resistance in response to multimodal sensory inputs and higher commands.
Role of the retrotrapezoid nucleus/parafacial respiratory group in coughing and swallowing in guinea pigs.
TLDR
It is raised the prospect that the RTN/pFRG contributes to expiratory regulation during normal respiration, although this region is not an essential element of the neuronal networks involved in coughing and swallowing.
Production of reflex cough by brainstem respiratory networks.
Blood pressure changes alter tracheobronchial cough: computational model of the respiratory-cough network and in vivo experiments in anesthetized cats.
TLDR
The effects of BP on coughing likely originate from interactions between barosensitive and respiratory brainstem neuronal networks, particularly by modulation of respiratory neurons within multiple respiration/cough-related brainstem areas by baroreceptor input.
The Kölliker‐Fuse nucleus gates the postinspiratory phase of the respiratory cycle to control inspiratory off‐switch and upper airway resistance in rat
TLDR
It is concluded that descending KF inputs are essential to gate PI activity required for a proper pattern formation and phase control within the respiratory network, at least during absence of pulmonary stretch receptor activity and that the KF contains large numbers of laryngeal PI premotor neurons that might have a key role in the regulation of upper airway resistance during reflex control and vocalization.

Medullary raphe neuron activity is altered during fictive cough in the decerebrate cat.
TLDR
Results suggest involvement of midline neurons (i.e., raphe nuclei) in the cough reflex in cats, and suggest that multiple factors influence the discharge patterns during coughing: e.g., respiratory-modulated and tonic inputs and intrinsic connections.
Medullary respiratory neurones and control of laryngeal motoneurones during fictive eupnoea and cough in the cat
TLDR
The data confirm and extend previous results on the control of laryngeal motoneurones during eupnoea and support the hypothesis that the same premotor neurones help to shape mot oneurone firing patterns during both eupoa and coughing.
Ventrolateral medullary respiratory network and a model of cough motor pattern generation.
TLDR
The two main conclusions were as follows: 1) The Bötzinger/rostral ventral respiratory group neurons implicated in the generation of the eupneic pattern of breathing also participate in the configuration of the cough motor pattern, and 2) This altered activity of B Ötzinger /rostral ventilation group neurons is transmitted to phrenic, intercostal, and abdominal motoneurons via the same bulbospinal neurons that provide descending drive during eupnea.
Cough, expiration and aspiration reflexes following kainic acid lesions to the pontine respiratory group in anesthetized cats.
TLDR
The results indicate the significant role of pons in the multilevel organization of brainstem networks in central integration of the aforementioned reflexes.
Influence of pulmonary inflations on discharge of pontile respiratory neurons.
TLDR
Results support the concept that the discharge of neurons in the pneumotaxic region may exert phasic, as well as tonic, influences on ventilatory activity.
Medullary respiratory-related neurons with axonal connections to rostral pons and their function in termination of inspiration
TLDR
A neuronal model for a pontine mechanism terminating inspiration is proposed in urethane-anaesthetized, paralyzed and artificially ventilated rabbits and it is proposed that RRU receive descending excitatory and inhibitory afferents as well as ascending efferents.
Functional connectivity among ventrolateral medullary respiratory neurones and responses during fictive cough in the cat
TLDR
The concurrent responses and multiple short time scale correlations support parallel and serial network interactions proposed in the model for the generation of the cough motor pattern in the respiratory pump muscles.
Central nervous mechanisms of cough.
TLDR
These findings support the existence of multifunctional neural networks in the mammal brainstem and indicate that the Bötzinger complex and the caudal ventral respiratory group have a crucial role in determining both the inspiratory and the expiratory components of the cough motor pattern.
