Serotonin and substance P: Synergy or competition in the control of breathing
Cholinergic inputs to laryngeal motoneurons functionally identified in vivo in rat: A combined electrophysiological and microscopic study
TLDR
It is demonstrated that LMNs identified in Sprague–Dawley rat receive several close appositions from vesicular acetylcholine transporter‐immunoreactive (VAChT‐ir) boutons, supporting a strong influence of cholinergic input on LMNs and may have implications in the differential modulation of laryngeal muscle activity.
Catecholamine inputs to expiratory laryngeal motoneurons in rats
TLDR
Details of the extent and distribution of potential catecholamine inputs to the expiratory laryngeal motoneuron are demonstrated, and it is indicated that the inputs, at least in part, originate from the dorsomedial medulla, providing a potential anatomical basis for previously reported catechlaminergic effects on the larynx.
Peptides, serotonin, and breathing: the role of the raphe in the control of respiration.
Medullary mediation of the laryngeal adductor reflex: A possible role in sudden infant death syndrome
Neuronal Mechanisms Underlying the Laryngeal Adductor Reflex
TLDR
The R1 response appears to be the result of the short-latency action potentials, orthodromically activated by ipsilateral stimulation of the superior laryngeal nerve (SLN), and the R2 response is likely to be a result ofThe long-latencies action possibles that can be recorded from ELMs on both sides.
Substance P, tyrosine hydroxylase and serotonin terminals in the rat caudal nucleus ambiguus
Recurrent laryngeal nerve activity exhibits a 5-HT-mediated long-term facilitation and enhanced response to hypoxia following acute intermittent hypoxia in rat.
TLDR
It is concluded that AIH induces neural plasticity in laryngeal motoneurons, via serotonin-mediated mechanisms similar to that observed in phrenic mot oneurons: the so-called "Q-pathway".
Distribution of Fos-Like Immunoreactivity, Catecholaminergic and Serotoninergic Neurons Activated by the Laryngeal Chemoreflex in the Medulla Oblongata of Rats
TLDR
The distribution of medullary nuclei that were activated by the LCR was demonstrated, and it was demonstrated that catecholaminergic neurons of the SolDL and serotoninergic neuron of the ROb wereactivated by the laryngeal lumen of adult rats, indicating the potential central pathway of the L CR.
The temporal relationship between non‐respiratory burst activity of expiratory laryngeal motoneurons and phrenic apnoea during stimulation of the superior laryngeal nerve in rat
TLDR
A temporal, sequential relationship between excitation of expiratory laryngeal motoneurons that close the larynx during swallowing, and inhibition of breathing, during stimulation of the SLN in rat is reported.

Serotonin inputs to inspiratory laryngeal motoneurons in the rat
TLDR
A significant serotonin input to inspiratory laryngeal motoneurons is demonstrated, which is more prominent on CT compared with PCA mot oneurons, and may reflect the different functional role of the muscles that they innervate during the sleep–wake cycle.

Serotonin immunoreactive boutons make synapses with feline phrenic motoneurons
TLDR
Results suggest that serotonin-containing neurons may directly affect the excitability of phrenic motoneurons, mainly through an input onto their extensive dendritic trees.

TLDR
