The carotid chemoreceptor discharge responses to hypoxia and hypercapnia were
quantitatively compared between normotensive (NTR) and spontaneously hypertensive rats …

Contribution of autonomic nervous system activity to the heart rate and blood pressure
responses during chemoreceptor excitations by systemic hypoxia and hypercapnia and to …

Carotid sinus nerve afferent activity was recorded in the peripheral end of the cut carotid
sinus nerves in rats anesthetized with urethane, paralyzed and artificially ventilated with …

Key points• Carbon dioxide (CO2) provides a major chemical stimulus to breathe, primarily
through the activity of CO2/pH sensors called chemoreceptors in the brainstem and in the …

Ventilatory responses to transient stimulation and inhibition of arterial chemoreceptors--by
hypoxia and hyperoxia, respectively--were studied in 10 pentobarbitone-anesthetized rats …

Key Points The influence of specific carotid body (CB) normoxic hypocapnia, hypercapnia
and normocapnia on the ventilatory sensitivity of central chemoreceptors to systemic …

The effects of both bolus injection and constant infusion of various levels of norepinephrine
(NE) on the activity of single-carotid chemoreceptor nerve fibers was studied in pentobarbital …

The steady-state stimulus-response relations between arterial pq, and P CO 2, and the
mean activity of carotid chemoreceptors (single and multi-fiber) and ventilation were …

METHODS Experiments were performed on dogs anesthetized with intravenous
chloralose(50 mg/kg) and urethan(750 mg/kg). The animals were subjected to thoracotomy …

The ventilatory response to hypoxia is augmented by muscular exercise. In order to
determine the role of peripheral chemoreceptors in the ventilatory response during hypoxic …
