Abstract
From the investigations of M. Fog, H. S. Forbes, G. I. Mchedlishvili, H. G. Wolff [1, 2, 3, 4, 5, 6] and others it is known, that the pial arteries change their diameter with any change of cerebrovascular resistance. But, it was unknown, to what extent the arterial vessels in the pia contribute to the blood flow resistance and to what degree their diameter changes give rise to alterations of the total cerebrovascular resistance. The experiments to be described were carried out to study the possible role of the pial arteries in the flow resistance by determinations of the pressure drop from the aorta to large and small pial arteries.
