摘要：

Using gradient‐echo echo‐planar MRI, a local signal increase of 4.3 ± 0.3% is observed in the human brain during task activation, suggesting a local decrease in blood deoxyhemoglobin concentration and an increase in blood oxygenation. Images highlighting areas of signal enhancement temporally correlated to the task are created. © 1992 Academic Press, Inc. Copyright © 1992 Wiley‐Liss, Inc., A Wiley Company
