METHODS Patients underwent (15)O PET and were randomized if OEF ratio was >1.13 on the(More)
BACKGROUND Cerebral blood flow (CBF) regulation is a critical element in cerebrovascular pathophysiology, particularly in large vessel disease, but the best method to use for hemodynamic assessment is not clear. We examined 4 different blood-flow related measures in patients with unilateral high-grade carotid artery disease, assessing asymmetry between the(More)
BACKGROUND Reducing inhibitory neurotransmission with pharmacological agents is a potential approach for augmenting plasticity after stroke. Previous work in healthy subjects showed diminished intracortical inhibition after administration of theophylline. OBJECTIVE We assessed the effect of single-dose theophylline on intracortical and interhemispheric(More)
