Coronary chemoreflex evoked by intrapericardial nicotine has a somatic component

, 1997
Stimulation of vagally innervated cardiac or pulmonary receptors reflexly evokes depressor responses called the coronary chemoreflex and pulmonary depressor reflex, respectively.

Update on vascular control of central chemoreceptors

Experimental Physiology
At least four mechanisms have been proposed to elucidate how neurons in the retrotrapezoid (RTN) region sense changes in CO2/H+ to regulate breathing (i.e., function as respiratory chemosensors).

Enhanced peripheral chemoreflex function in conscious rabbits with pacing-induced heart failure

, 1999
The present study aimed to determine whether peripheral and/or central chemoreflex function is altered in chronic heart failure (CHF) and whether altered chemoreflex function contributes to sympathetic activation in CHF.

Autonomic processing of the cardiovascular reflexes in the nucleus tractus solitarii

Brazilian Journal of Medical and Biological Research, 1997
The nucleus tractus solitarii (NTS) receives afferent projections from the arterial baroreceptors, carotid chemoreceptors and cardiopulmonary receptors and as a function of this information produces autonomic adjustments in order to maintain arterial ...

Carotid chemoreflex control of blood pressure at rest and during exercise in young‐onset hypertension

Despite reports of amplified carotid chemoreflex sensitivity to hypoxia in young adults with hypertension (<40 years), it is unclear whether this equates to a direct role of this reflex in maintaining high resting and exercise blood pressures (BP ...

Effects of alcohol on sympathetic activity, hemodynamics, and chemoreflex sensitivity.

, 1997
Alcohol intake has been shown to worsen obstructive sleep apnea and increase nocturnal hypoxemia. The mechanisms of this action are unclear. Animal studies suggest that a reduction in chemoreflex sensitivity may be implicated.

Alteration of capsaicin-induced pulmonary chemoreflex following chronic cervical spinal cord injury

, 2014
High cervical spinal cord injury usually changes the respiratory pattern, which may influence the pulmonary vagal afferent activity. Previous study revealed that pulmonary chemoreflex cannot be evoked following acute C2 hemisection (C2Hx).
