Arterial pressures in the Circle of Willis were measured in dogs subjected to positive pressure breathing. Catecholamines in hypothalamus and adrenals were measured in sacrificed animals. Pathologic changes in brain tissue were demonstrated. Pressure changes and catecholamine variations are discussed.
