Local increases in neuronal activity induce augmentations in local metabolism, which are compensated for by increases in blood supply. Thus, increases in cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO2) have been used as criteria for increases in neuronal activity. However, it has been impossible to detect these events in the timedimension as closely as is practical. Currently, near-infrared spectroscopy (NIRS) , which achieves a high temporal resolution (1 second) , enables continuous real-time measurements.
