Blood pressure, heart rate, sympathetic nerve activity, and polysomnography were recorded
during wakefulness and sleep in 10 patients with obstructive sleep apnea. Measurements …

Background The early hours of the morning after awakening are associated with an increased
frequency of events such as myocardial infarction and ischemic stroke. The triggering …

Background Spectral analysis of RR interval and systolic arterial pressure variabilities may
provide indirect markers of the balance between sympathetic and vagal cardiovascular …

We tested the hypothesis that sympathetic nerve responses to stimulation of chemoreceptors
by hypoxia are exaggerated in borderline hypertensive humans. We compared responses …

We compared the effects of isocapnic hypoxia (IHO) and hyperoxic hypercapnia (HC) on
sympathetic nerve activity (SNA) recorded from a peroneal nerve in 13 normal subjects. HC …

Acid-sensing ion channel (ASIC) 1a subunit is expressed in synapses of central neurons
where it contributes to synaptic plasticity. However, whether these channels can conduct Ca 2+ …

Animal studies have demonstrated that activation of the baroreflex by increases in arterial
pressure inhibits cardiovascular and ventilatory responses to activation of peripheral …

Arterial baroreceptors provide a neural sensory input that reflexly regulates the autonomic
drive of circulation. Our goal was to test the hypothesis that a member of the acid-sensing ion …

The sympathetic response to hypoxia depends on the interaction between chemoreceptor
stimulation (CRS) and the associated hyperventilation. We studied this interaction by …

Activation of stretch-sensitive baroreceptor neurons exerts acute control over heart rate and
blood pressure. Although this homeostatic baroreflex has been described for more than 80 …
