[Functional stability of the cerebral circulatory system].
Functional stability of the cerebral circulation system seems to be based on the active mechanisms and on those stemming from specifics of the biophysical structure of the system under study. This latter parameter has some relevant criteria for its quantitative estimation. Analysis of common data on various effects upon cerebral vessels shows an essential difference between the functional stability and the idea of "autoregulation of the cerebral circulation". The data obtained suggest that the essential part of the mechanism for active responses of cerebral vessels which maintains the functional stability of this portion of the vascular system, consists of a neurogenic component involving central nervous structures localized, for instance, in the medulla oblongata.
