Neuro-Vascular Efficiency

Meaning

Neuro-Vascular Efficiency is the optimal functional coupling between neuronal activity and the cerebral blood flow that supplies the active brain regions with necessary oxygen and nutrients. This metric represents the swiftness and precision with which the cerebral vasculature dilates or constricts to match the metabolic demands of localized neuronal firing. High efficiency is critical for supporting peak cognitive performance, as it ensures immediate and adequate energy delivery to areas engaged in complex thought, thereby protecting against ischemic stress and enhancing neuroplasticity.
