Dynamics of blood flow and oxygenation changes during brain activation: The balloon model
A biomechanical model is presented for the dynamic changes in deoxyhemoglobin content during brain activation. The model incorporates the conflicting effects of dynamic changes in both bloodExpand

Processing strategies for time‐course data sets in functional mri of the human brain
TLDR
Image processing strategies for functional magnetic resonance imaging (FMRI) data sets acquired using a gradient‐recalled echo‐planar imaging sequence are considered. Expand

Involvement of striate and extrastriate visual cortical areas in spatial attention
We investigated the cortical mechanisms of visual-spatial attention while subjects discriminated patterned targets within distractor arrays. Functional magnetic resonance imaging (fMRI) was used toExpand

Quantitative imaging of perfusion using a single subtraction (QUIPSS and QUIPSS II)
In the pulsed arterial spin labeling (ASL) techniques EPISTAR, PICORE, and FAIR, subtraction of two images in which inflowing blood is first tagged and then not tagged yields a qualitative map ofExpand

Time course EPI of human brain function during task activation
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 concentrationExpand
