Differential suppression of upper airway motor activity during carbachol-induced, REM sleep-like atonia.
It is concluded that pontine carbachol evokes a stereotyped pattern of suppression of upper airway motor activity that was significantly greater than the depression caused by a level of hypocapnia that reduced Phr activity as much ascarbachol.
Localization of the “sneeze center”
The most recent description of a patient with systemic lupus erythmatosus–related demyelination who had ASR with a persisting lesion in the area of sneeze center is further evidence that ASR results from a well-defined brainstem lesion.
Microinjection of kynurenic acid in the rostral nucleus of the tractus solitarius disrupts spatiotemporal aspects of mechanically induced tracheobronchial cough.
The results are consistent with the existence of a critical component of the cough rhythmogenic circuit located in the rostral ventral and lateral NTS and significant elimination of neurons in the solitary tract nucleus results in cough apraxia.
Stereotyped yawning responses induced by electrical and chemical stimulation of paraventricular nucleus of the rat.
The sequential events of yawning may be generated by NOS-containing parvocellular neurons in the medial part of the rostral PVN projecting to the lower brain stem in anesthetized, spontaneously breathing rats.


Neural mechanisms of sneeze.
Temporal characteristics of the silent periods, "inhibitory gaps," suggested that they resulted from inhibition whose source was the expiratory neurons which were driven throughout inspriation, and some inspiratory neurons in the area of fasciculus solitarius failed to exhibit inhibitory gaps.
Re-examination of centrally-induced cough in cats using a micro-stimulation technique.
The results indicate that the area, in which the cough-like response is produced by electrical stimulation, is confined distinctly to a certain anatomical structure of the medulla, i.e., the nucleus tractus solitarius.
Central projections of the ethmoidal nerve of the cat as determined by the horseradish peroxidase tracer technique
The objective of this study was to localize the cell bodies of these ethmoidal afferents and to trace the central projections of these neurons, which are thought to be a part of the trigeminal system rather than olfactory in nature.

The localization of the central cough mechanism was studied by electrically stimulating the lower brainstem in cats lightly anesthetizing with pentobarbital sodium or in unanesthetized midcollicular decerebrate preparations, suggesting that these agents act centrally to suppress the cough responses.
A stereotaxic atlas of the cat brain
There are excellent regional atlases for both the cat and the monkey, but these are the first to cover the brain stem and basal telenccphalon in such a complete fashion and should prove of particular value to people working in the caudal brain stem.
Muscular, bronchomotor and cardiovascular reflexes elicited by mechanical stimulation of the respiratory tract
1. The effects of mechanical stimulation in the nose, epipharynx, laryngopharynx and tracheobronchial tree, and of chemical irritation of the nasal mucosa, were studied on various somatic and
Comments on Microelectrodes
Metal-filled microelectrodes are best for high-frequency work; fluid-filled ones are best for low frequencies and dc. Both have advantages and drawbacks. This paper gives the results of experience
