Rat brains also have a default mode network
The default mode network (DMN) in humans has been suggested to support a variety of cognitive functions and has been implicated in an array of neuropsychological disorders. However, its function(s)Expand

Resting-State Glutamate and GABA Concentrations Predict Task-Induced Deactivation in the Default Mode Network
Deactivation of the human brain's default mode network (DMN) is regarded as suppression of endogenous activity to support exogenous task-related processes. This phenomenon has important functionalExpand

Large-scale brain network coupling predicts acute nicotine abstinence effects on craving and cognitive function.
IMPORTANCE Interactions of large-scale brain networks may underlie cognitive dysfunctions in psychiatric and addictive disorders. OBJECTIVES To test the hypothesis that the strength of couplingExpand

Intrinsic resting‐state activity predicts working memory brain activation and behavioral performance
Although resting‐state brain activity has been demonstrated to correspond with task‐evoked brain activation, the relationship between intrinsic and evoked brain activity has not been fullyExpand

Simultaneous MRI acquisition of blood volume, blood flow, and blood oxygenation information during brain activation
TLDR
A new MRI technique is presented that is able to achieve concurrent acquisition of three hemodynamic images based primarily on the changes of cerebral blood volume, blood flow, and blood oxygenation, respectively, associated with brain activation. Expand
