A review of pharmacological, neuroanatomical, electrophysiological, and behavioral data
indicates that systems controlling cardiovascular function are closely coupled to systems …

An increasing amount of anatomical, physiological, and pharmacological evidence suggest
that pain inhibitory circuitry is linked with cardiovascular regulatory systems in man and …

Recent studies have demonstrated a hypoalgesia in hypertensive subjects. This study
reports and evaluates factors responsible for the expression of the hypoalgesic behavior …

Responsiveness to sensory stimulation can undergo marked changes during the daily life
cycle. The sleeping or drowsy person may not respond to auditory or tactile stimuli which …

Endogenous pain regulatory system dysfunction appears to play a role in the maintenance
of chronic pain. An important component of the pain regulatory process is the functional …

Cardiovascular and Pain Regulatory Systems. Several recent findings provide evidence that
cardiovascular and pain regulatory systems are interactive. The physiological responses to …

Sinoaortic and cardiopulmonary baroreceptor reflex arcs represent the primary mechanisms
for maintaining circulatory homeostasis. These arcs utilize both peripheral receptors and …

Baroreceptor activity has been implicated in the modulation of pain. Sensory detection
thresholds and pain ratings were measured in a group of 28 men during carotid …

The relationship between pain and hypertension is potentially of great pathophysiological
and clinical interest, but is poorly understood. The perception of acute pain initially plays an …

To test the hypothesis that hypertension diminishes pain perception, a study was made that
evaluated the relation between arterial blood pressure and thermal pain perception in …
