Psychological Status Monitoring with Cerebral Blood Flow: CBF, Electroencephalogram: EEG and Electro-Oculogram: EOG Measurements [PDF]

open access: yes, 2015
—Psychological status monitoring with cerebral blood flow (CBF), EEG and EOG measurements are attempted. Through experiments, it is confirmed that the proposed method for psychological status monitoring is valid.

THE NITROUS OXIDE METHOD FOR THE QUANTITATIVE DETERMINATION OF CEREBRAL BLOOD FLOW IN MAN: THEORY, PROCEDURE AND NORMAL VALUES.

open access: yesJournal of Clinical Investigation, 1948
In 1945 the authors reported the determination of cerebral blood. flow in man by the use of nitrous oxide in low concentration, a technique which permitted for the first time quantitative clinical measurement of this important physiologic function (1 ...

Experimental carotid baroreceptor stimulation reduces blood flow velocities in the anterior and middle cerebral arteries of healthy individuals

open access: yesJournal of Physiological Sciences, 2023
This study investigated effects of experimental baroreceptor stimulation on bilateral blood flow velocities in the anterior and middle cerebral arteries (ACA and MCA) using functional transcranial Doppler sonography. Carotid baroreceptors were stimulated

Towards Assistive Diagnoses in m-Health: A Gray-box Neural Model for Cerebral Autoregulation Index [PDF]

open access: yesarXiv, 2020
The cerebral autoregulation system (CAS), is a mechanism which aims to regulate pressure variations occurring in the cerebral circulatory system. At present, there only exist invasive methods and, in turn, they are not used to prevent cerebrovascular accidents.
