Figure 1 Neurovascular coupling mechanisms. Performing brain activities, such as sensory, cognitive, and motor tasks, leads to activation of the corresponding cortex. This activation causes changes in local oxygen metabolism rates and local cerebral blood flow dynamics. The increase in local cerebral blood flow in the activated regions of the brain exceeds the local oxygen consumption rate, resulting in increased oxyhemoglobin concentrations and decreased deoxyhemoglobin concentrations in these regions.
