Abstract :
The feasibility of measuring the individual input impedance in each primary arterial input to intracranial structures was examined in the anesthetized dog. From a Fourier analysis of experimental pressures and flows, carotid and vertebral input impedances with the corresponding components of hydraulic power were computed, giving the anterior, posterior, and total cerebrovascular impedances.
