Conference paper


Regional cerebral blood flow (rCBF) is normally coupled to neuronal function. Increased neuronal activity needs enhanced rCBF to meet metabolic demands. Given the decreased dilatory capacity of the cerebral vessels in occlusive vascular disease [16], we studied the adapatation of flow to function in stroke patients. Specifically, we asked whether the cognitive dysfunction of stroke victims can be explained by impaired adaptability of rCBF to mental activity.
