Abstract

Functional brain Imaging in humans has revealed task-specific increases inbrain activity that are associated with various mental activities. In the same studies, mysterious, task-Independent decreases have also frequently been encountered, especially when the tasks of interest have been compared with a passive state, such as simple fixation or eyes closed. These decreases have raised the possibility that there might be a baseline or resting state of brain function involving a specific set of mental operations. We explore this possibility, including the manner in which we might define a baseline and the implications of such a baseline for our understanding of brain function.
