Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Measurement of Intraspinal Pressure After Spinal Cord Injury: Technical Note from the Injured Spinal Cord Pressure Evaluation Study. [PDF]

, 2016
Intracranial pressure (ICP) is routinely measured in patients with severe traumatic brain injury (TBI). We describe a novel technique that allowed us to monitor intraspinal pressure (ISP) at the injury site in 14 patients who had severe acute traumatic ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Automated Measurement of Adherence to Traumatic Brain Injury (TBI) Guidelines using Neurological ICU Data [PDF]

, 2018
Using a combination of physiological and treatment information from neurological ICU data-sets, adherence to traumatic brain injury (TBI) guidelines on hypotension, intracranial pressure (ICP) and cerebral perfusion pressure (CPP) is calculated ...

Individuals with persisting post‐concussion symptoms with physiological subtype demonstrate altered cardiovascular and autonomic responses to face cooling

Experimental Physiology, EarlyView.
Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy

Neurovisceral phenotypes in the expression of psychiatric symptoms [PDF]

, 2015
This review explores the proposal that vulnerability to psychological symptoms, particularly anxiety, originates in constitutional differences in the control of bodily state, exemplified by a set of conditions that include Joint Hypermobility, Postural ...

Acute exercise‐induced improvements in cognition: Role of cerebral blood flow and metabolism

Experimental Physiology, EarlyView.
Abstract Physical activity is widely recognized for its ability to promote brain health, with acute exercise transiently enhancing cognition and long‐term training attenuating cognitive decline. However, the mechanisms underlying these benefits remain incompletely understood.
