A Novel Measure of Instantaneous Baroreflex Sensitivity

Various time- and frequency-based approaches have been proposed to measure baroreflex sensitivity. All these methods are block-based ones. This study proposes a novel instantaneous measure of baroreflex sensitivity that enables the investigation of ...

Autonomic dysfunction measured by baroreflex sensitivity in markedly abnormal in stable cirrhosis despite minimal haemodynamic changes.

, 2008
Introduction: Autonomic dysfunction occurs in 43-80% of cases of cirrhosis, but is usually asymptomatic. The baroreflex arc is an important component of the autonomic nervous system main- taining cardiovascular status both at rest and during physio ...

Neurocardiology: Brain–Heart Interactions in the Heart

MedComm, Volume 7, Issue 9, September 2026.
The heart and brain maintain systemic homeostasis through bidirectional communication involving neural, biochemical, and mechanical pathways. Dysregulation of these pathways contributes to a spectrum of conditions involving heart–brain interactions, including Takotsubo syndrome, the epileptic heart, stroke–heart syndrome, heart failure, cardiac ...

Relationship Between Sympathetic Baroreflex Sensitivity and Arterial Stiffness in Elderly Men and Women

, 2012
Previous human studies have shown that large-artery stiffness contributes to an age-related decrease in cardiovagal baroreflex sensitivity. Whether this is also true with sympathetic baroreflex sensitivity is unknown.

Cholecystokinin Induces Ca2+ Transients in Brainstem Neurons, Astrocytes and Central Vagal Terminals in Jugular/Nodose Ganglia–Brainstem Slice Cultures

European Journal of Neuroscience, Volume 64, Issue 5, September 2026.
A jugular/nodose ganglion–brainstem slice culture with intact ganglia attached to the brainstem, preserving functional vagal afferent pathways to the brainstem. In this preparation, cholecystokinin activates brainstem neurons, central vagal terminals and brainstem astrocytes, establishing this preparation as a powerful model for dissecting the neuro ...

Average Real Variability Is an Independent Predictor of Increased Arterial Stiffness Assessed by Pulse Wave Velocity

The Journal of Clinical Hypertension, Volume 28, Issue 9, September 2026.
ABSTRACT Blood pressure variability (BPV) is an established cardiovascular risk factor associated with target organ damage beyond mean blood pressure levels. Arterial stiffness, assessed by carotid–femoral pulse wave velocity (cfPWV), represents an early manifestation of hypertension and an independent predictor of cardiovascular events.

Body Posture‐Related Differences in Pain Perception and Their Mediation by Cardiovascular Factors

Psychophysiology, Volume 63, Issue 9, September 2026.
ABSTRACT Pain modulation arising from the cardiovascular system has repeatedly been described. It is mediated by the baroreceptor system, where the activity of baroreceptor afferents inhibits nociception. Body posture changes cause blood volume redistribution that might modulate baroreceptor activity and antinociceptive effects. This study investigated

Age and sex differences in blood pressure regulation: A focus on the vascular baroreflex limb

Physiological Reports
Despite the vasculature's role in long‐term blood pressure (BP) regulation, limited work exists on vascular baroreflex function. This study focused on hypothesized age and sex differences in the vascular‐sympathetic baroreflex limb and explored the role ...

Toward an Understanding of the Psychological Meaning of Physiological Synchrony

Psychophysiology, Volume 63, Issue 9, September 2026.
ABSTRACT Physiological synchrony—coordinated changes in physiological activity between individuals—is a frequently studied yet variably interpreted phenomenon in psychological science. Decades of research show that physiological synchrony is ubiquitous across relationship and social contexts, but consensus remains elusive about what it means ...

Haemodynamic responses to head‐up tilt versus lower‐body negative pressure in type 1 diabetes

Experimental Physiology, Volume 111, Issue 9, Page 4089-4102, 1 September 2026.
Abstract Head‐up tilt (HUT) and lower‐body negative pressure (LBNP) both reduce central blood volume but differ in heart orientation and regional fluid shifts. Whether they evoke comparable cardiovascular regulation when matched for preload remains uncertain.
