Abstract

The partial pressure of tissue oxygen (pO(2)) was measured in rat somatosensory cortex during periodic electrical forepaw stimulation of either 1 minor 4 s in duration, and correlated with simultaneous laser Doppler flowmetry. For both stimulus durations, a transient decrease in tissue pO(2) preceded blood flow changes, followed by a peak in blood flow and an overshoot in tissue pO(2) With protracted stimulation, tissue pO(2) remained only slightly above pre-stimulus baseline, while blood flow was maintained at a reduced plateau phase. A sustained post-stimulus undershoot in tissue pO(2) wasobserved only for the 1 min stimulus. These findings suggest a complex dynamic relationship between oxygen utilization and blood flow.
