Losing the dogmatic view of cerebral autoregulation
Physiological Reports, 2021 In 1959, Niels Lassen illustrated the cerebral autoregulation curve in the classic review article entitled Cerebral Blood Flow and Oxygen Consumption in Man.

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.

Advanced Materials, EarlyView.This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Tissue oxygenation dynamics during transition from seizure to spreading depolarization in rat brain
Epilepsia, EarlyView.Abstract Objective Spreading depolarization (SD) is a phenomenon underlying various neurological conditions, including epilepsy. Researchers have suspected that local tissue oxygenation breakdown induces spontaneous SD. In this study, we investigated the relationship between spontaneous epileptic seizures and SD, with a focus on the role of local ...

Effect of head-upright tilt on the dynamic of cerebral autoregulation. [PDF]
, 1998 The effect of head-upright tilting on the rate of cerebral autoregulation was studied in 12 healthy volunteers (nine men and three women; age range 20-36 years).

Impaired Dynamic Cerebral Autoregulation in Cerebral Venous Thrombosis
Frontiers in Neurology, 2020 Background: Cerebral autoregulation is crucial in traumatic brain injury, which might be used for determining the optimal intracranial pressure. Cerebral venous thrombosis (CVT) is a cerebral vascular disease with features of high intracranial pressure ...

Mathematical modeling of local perfusion in large distensible microvascular networks [PDF]
, 2016 Microvessels -blood vessels with diameter less than 200 microns- form large, intricate networks organized into arterioles, capillaries and venules. In these networks, the distribution of flow and pressure drop is a highly interlaced function of single ...

METHOD FOR DETERMINING THE UPPER LIMIT OF CEREBRAL AUTOREGULATION IN RATS
Фармация и фармакология (Пятигорск), 2018 The main objective of the phenomenon of cerebral autoregulation is to maintain a constant cerebral blood flow rate with changes in systemic arterial pressure in the range of 50 mmH up to 150 Mmhg.
