Scaling of brain metabolism and blood flow in relation to capillary and neural scaling [PDF]
PLoS ONE 6(10): e26709 (2011), 2011 Brain is one of the most energy demanding organs in mammals, and its total metabolic rate scales with brain volume raised to a power of around 5/6. This value is significantly higher than the more common exponent 3/4 relating whole body resting metabolism with body mass and several other physiological variables in animals and plants.

Cerebral blood flow autoregulation is impaired in schizophrenia [PDF]
, 2017 Patients with schizophrenia have a higher risk of cardiovascular diseases and higher mortality from them than does the general population; however, the underlying mechanism remains unclear.

Cardiac Output and Cerebral Blood Flow: The Integrated Regulation of Brain Perfusion in Adult Humans
Anesthesiology, 2015 Cerebral blood flow (CBF) is rigorously regulated by various powerful mechanisms to safeguard the match between cerebral metabolic demand and supply. The question of how a change in cardiac output (CO) affects CBF is fundamental, because CBF is dependent

Postishemic Cerebral Function and Blood Flow
Общая реаниматология, 2005 The impact of massive blood loss on cerebral blood flow-function relationships was studied in rats in the postis-chemic period. Anxiety was examined in the raised cross-shaped labyrinth.

Real-Time Phase Contrast MRI to quantify Cerebral arterial flow change during variations breathing [PDF]
arXiv, 2022 Cerebral arterial blood flow (CABF) can be investigated in few seconds without any synchronization by Real-Time phase contrast. Significant changes in CABF were found between expiration and inspiration during normal breathing of healthy volunteers. Synopsis (100/100) Real-time phase contrast MRI has been applied to investigate cerebral arterial blood ...

Statistical physics of cerebral embolization leading to stroke [PDF]
Phys. Rev. E vol. 80, 051912 (2009), 2008 We discuss the physics of embolic stroke using a minimal model of emboli moving through the cerebral arteries. Our model of the blood flow network consists of a bifurcating tree, into which we introduce particles (emboli) that halt flow on reaching a node of similar size.

Aging alters the dampening of pulsatile blood flow in cerebral arteries
Journal of Cerebral Blood Flow and Metabolism, 2016 Excessive pulsatile flow caused by aortic stiffness is thought to be a contributing factor for several cerebrovascular diseases. The main purpose of this study was to describe the dampening of the pulsatile flow from the proximal to the distal cerebral ...
