...increase in blood flow and oxygen consumption can be picked up with various modern imaging techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). It is assumed that local increase in blood flow means that the brain area involved is doing the processing....

...traditional cortical sites of language, Broca's and Wernicke's areas, is unclear. However, new techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (FMRI) may help us solve the mystery. These techniques allow us to determine what parts of the human brain...

...brain, in both normal subjects and those with brain disorders. One of the unique features of techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) is that data are obtained from essentially the entire brain simultaneously. These potentially rich...

...Through Neural Interactions Anthony Randal Mclntosh University of Toronto, Canada Brain imaging methods, such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), provide a unique opportunity to study the neurobiology of human memory. As these methods can measure...

...variables (such as the location of the subject) might have been. Recently, nonintrusive techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) have become available for examining the human brain (see Orrison et al., 1995). Both of these techniques...

...widely distributed functions) is also a ubiquitous premise of the most modern work using brain scans such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). In short, localized modularity has been with us for many years and continues to be a mainstay of modern...

...The future for research on disorders affecting the brain is also a bright one New imaging techniques, such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), promise advances in our ability to identify regions of the brain associated with cognitive and affective...

...research, as, for example, in studies using knock-out mice. The use of noninvasive brain imaging techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) allows researchers to watch how the brain responds to doses of a drug. Researchers at Harvard used...

...tasks that require it to shift its attention from one task to another. The development of powerful new imaging technologies such as positron emission tomography...(PET) and functional magnetic resonance imaging (fMRI) is giving researchers the extraordinary ability to study the neural bases of a variety of cognitive...
