RHEOENCEPHALOGRAPHY

Rheoencephalography (REG) The Core Definition of Rheoencephalography Rheoencephalography (REG) is a non-invasive biomedical technique utilized for the continuous registration and assessment of pulsatile changes in the electrical impedance of the head, which primarily reflect variations in cerebral blood volume associated with each heartbeat. In essence, it provides an indirect measure of the dynamic characteristics of […]

RHEOENCEPHALOGRAPH

Rheoencephalography (REG) The Core Definition of Rheoencephalography Rheoencephalography, commonly abbreviated as REG, is defined as a non-invasive, bioelectrical technique used in clinical neurophysiology to measure changes in the electrical impedance of the brain tissue. These impedance changes are primarily correlated with the pulsatile flow of blood through the cerebral vasculature during the cardiac cycle. In […]
