Abstract
The methodology of the Laguerre-Volterra network for systems with fast and slow dynamics was used to study dynamic autoregulation of cerebral hemodynamics. A nonlinear model including low-frequency autoregulation dynamics was obtained for the purpose. Cerebral autoregulation was found to be a nonlinear and frequency-dependent system with considerable nonstationarities.
