Introduction: The baroreceptor reflex mediated heart rate response is generally estimated by complex cross-spectral analysis (transfer function gain) between R-R interval and systolic blood pressure ...

Introduction: The baroreceptor reflex (BR) is the most prominent short-term compensator during blood pressure (BP) challenges. Aim: To study the effect of postconceptional age (PCA, gestational age + ...

Blood pressure modulates a person's tendency to worry and can be associated with a "tranquilizing" effect when elevated. This is indicated in a new study that reflects how we can implicitly learn to ...

The baroreceptor reflex is a fascinating medical phenomenon. The reflex is controlled by specialized neurons that react in just a fraction of a second to keep blood pressure fairly consistent. For ...

The physiologic mechanisms involved in the human's adaptation to endurance exercise training result in the endurance exercise trained individual having high maximal oxygen uptakes (V͘O2max) and being ...

New research suggests that young women with a family history of high blood pressure (hypertension) have decreased baroreflex function, which may increase their risk for hypertension later in life. The ...

Pharmacology researchers found that a recently identified enzyme in the brain plays a critically important role in the central regulation of blood pressure. The researchers showed that ...

Background: Epidemiologic studies suggest a positive association between fine particulate matter and arterial blood pressure, but the results have been inconsistent. Objectives: We investigated the ...

What is the name of the physiologic mechanism (reflex) that is thought to cause sinus arrhythmia? The Bainbridge reflex (atrial reflex) occurs when the heart increases in response to an increase in ...

Two proteins -- PIEZO1 and PIEZO2 that sense blood pressure and help control the baroreceptor reflex have been discovered by scientists at Scripps Research. The baroreceptor reflex is a fascinating ...
