## Abstract Echo‐planar magnetic resonance (MR) imaging was used to observe signal intensity changes in the human brain during hypoxia. Increasing arterial blood levels of deoxyhemoglobin (0%–42%) during prolonged apnea were monitored with a pulse oximeter and correlated with gray matter and white

Abstract
When deoxygenated, blood behaves as an effective susceptibility contrast agent. Changes in brain oxygenation can be monitored using gradient‐echo echo‐planar imaging. With this technique, difference images also demonstrate that blood oxygenation is increased during periods of recovery from respiratory challenge. © 1991 Academic Press, Inc.

## Abstract Brain function is widely investigated with functional magnetic resonance imaging (fMRI) in humans and animals. In fMRI, the time courses of voxels typically reflect the local blood‐oxygen level, which is taken as an indicator of neuronal activity. Voxel time‐course correlations are ofte
