The hemodynamics of the brain is, to a large extent, determined by the cerebrovascular resistance which is dependent, in its turn, on the functional state of the whole vascular system, starting from the arteries entering the skull and ending with the veins draining blood from the brain. Hence the need for obtaining the fullest information possible concerning the behavior of all portions of the vascular system of the brain under all conditions studied. This is why, in the investigations on which the present book is based, the methods commonly used were those which simultaneously indicated the functional behavior of different parts of its vascular system. If this was impossible, or if the information obtained was insufficient to give a complete picture of behavior of the cerebrovascular system, several series of analogous experiments were carried out with appropriate variation of the parameters studied.
