A default mode of brain function

A baseline or control state is fundamental to the understanding of most complex systems. Defining a baseline state in the human brain, arguably our most complex system, poses a ...

Searching for a baseline: Functional imaging and the resting human brain

Medial prefrontal cortex and self-referential mental activity: Relation to a default mode of brain function

Medial prefrontal cortex (MPFC) is among those brain regions having the highest baseline metabolic activity at rest and one that exhibits decreases from this baseline across a w...

Emotion-induced changes in human medial prefrontal cortex: I. During cognitive task performance

Regional cerebral blood flow (BF) was examined in regions of the medial prefrontal cortex (MPFC) with positron-emission tomography while subjects performed two cognitive tasks, ...

Effect of practice on reading performance and brain function

Word reading is considered a highly over-learned task. If true, then practice should have no effect on its performance or associated functional brain anatomy. We tested this hyp...
