Abstract
In a recent review1 of the cerebral vasomotor phenomena, an explanation for the conflict of opinion concerning the existence of vasomotor control was presented. The discrepancy was attributed to the inadequate methods frequently employed, and especially to the absence of a quantitative method for directly measuring brain vessels. In this article, Forbes and one of us (H. G. W.) applied a method which was quantitative and direct for the measurement of cerebral vessels. The conclusion was reached that arteries of the brain responded by a change in diameter to stimulation of vasomotor nerves. If one accepts this experimental evidence that the nerves to the cerebral vessels have a vasomotor function, it is not unreasonable to expect that these nerves partially influence the tone of the capillaries as well as the arteries, even though the major regulation of the diameter of the brain vessels is chemical.2 The observations of
