Modeling of Cerebral Blood Flow Autoregulation Using Mathematical Control Theory
Mathematics, 2022 A mathematical model of cerebral blood flow in the form of a dynamical system is studied. The cerebral blood flow autoregulation modeling problem is treated as a nonlinear control problem and the potential and applicability of the nonlinear control ...

Cerebral Autoregulation in Man [PDF]
Stroke, 1974 Autoregulation was tested by regional blood flow (rCBF) and cardiohemodynamic measurements before and after induced systemic arterial hypertension in 16 patients with varying neurological disorders. Hypertension was induced by increasing the arterial blood pressure by an intravenous infusion of Aramine.

Cerebrovascular Impedance as a Function of Cerebral Perfusion Pressure
IEEE Open Journal of Engineering in Medicine and Biology, 2023 Goal: Cerebrovascular impedance is modulated by a vasoactive autoregulative mechanism in response to changes in cerebral perfusion pressure. Characterization of impedance and the limits of autoregulation are important biomarkers of cerebral health.

A stochastic delay differential model of cerebral autoregulation [PDF]
, 2015 Mathematical models of the cardiovascular system and of cerebral autoregulation (CAR) have been employed for several years in order to describe the time course of pressures and flows changes subsequent to postural changes. The assessment of the degree of
