The physiological basis for the interaction of selective attention and arousal is not clearly
understood. Here we present evidence in humans that specifically implicates the thalamus in …

… Thus, each session data set is surmised by a single contrast image whose voxel values
are the fitted response amplitudes. These contrast images can then be assessed at the …

Proton magnetic resonance spectroscopy can measure in vivo brain lactate and other
metabolites noninvasively. We measured the biochemical changes accompanying stroke in 16 …

Subject motion in functional magnetic resonance imaging (fMRI) studies can be accurately
estimated using realignment algorithms. However, residual changes in signal intensity arising …

A limitation of previous methods for studying human brain glucose metabolism, such as positron
emission tomography, is that metabolic steps beyond glucose uptake cannot be studied. …

Flow‐sensitive alternating inversion recovery (FAIR) is a pulsed arterial spin labeling magnetic
resonance imaging method for perfusion quantification. In its standard implementation for …

New variants of the ultra-high-speed echo-planar imaging technique have been used to
obtain snap-shot images of adult patients and volunteers at 0.1 T. Modified pulsed-gradient …

Gastrointestinal (GI) tract motility was depicted in four human volunteers with the high-speed
echo-planar imaging technique: modulus blipped echo-planar single-pulse technique (…

The ultra-high-speed echo-planar imaging technique produces instant snapshot magnetic
resonance images in exposure times ranging from approximately 10 to 100 msec. A particular …
