Traditionally studies of brain function have focused on task-evoked responses. By their very
nature, such experiments tacitly encourage a reflexive view of brain function. Although such …

The amount of data gathered with echo-planar blood oxygen level (BOLD)-weighted
functional MRI can be staggering. With commercially available equipment, it is routine to …

Highly accurate surface models of the cerebral cortex are becoming increasingly important
as tools in the investigation of the functional organization of the human brain. The …

Functional brain imaging with positron emission tomography and magnetic resonance
imaging has been used extensively to map regional changes in brain activity. The signal …

Following arm amputation the region that represented the missing hand in primary
somatosensory cortex (S1) becomes deprived of its primary input, resulting in changed …

POSITRON emission tomographic (PET) studies of human attention have begun to dissect
isolable components of this complex higher brain function, including a midline attentional …

Background and Purpose—The effect of ebselen, a seleno-organic compound with
antioxidant activity through a glutathione peroxidase–like action, on the outcome of acute …

Primary headache syndromes, such as cluster headache and migraine, are widely
described as vascular headaches, although considerable clinical evidence suggests that …

The representation of pain in the cerebral cortex is less well understood than that of any
other sensory system. However, with the use of magnetic resonance imaging and positron …

Pain is a diverse sensory and emotional experience that likely involves activation of
numerous regions of the brain. Yet, many of these areas are also implicated in the …
