The majority of functional neuroscience studies have focused on the brain's response to a
task or stimulus. However, the brain is very active even in the absence of explicit input or …

A series of recent empirical observations demonstrate structured activity patterns that exist
during passive task states. One observation is that a network of regions, referred to as the …

Variations in neural circuitry, inherited or acquired, may underlie important individual
differences in thought, feeling, and action patterns. Here, we used task-free connectivity …

Control regions in the brain are thought to provide signals that configure the brain's moment-
to-moment information processing. Previously, we identified regions that carried signals …

Brain anatomical networks are sparse, complex, and have economical small-world
properties. We investigated the efficiency and cost of human brain functional networks …

Functional neuroimaging and electrophysiological studies have documented a dynamic
baseline of intrinsic (not stimulus-or task-evoked) brain activity during resting wakefulness …

The traditional approach to studying brain function is to measure physiological responses to
controlled sensory, motor and cognitive paradigms. However, most of the brain's energy …

Alzheimer's disease (AD) is a neurodegenerative disorder that prominently affects cerebral
connectivity. Assessing the functional connectivity at rest, recent functional MRI (fMRI) …

Anterior cingulate cortex (ACC) is a nexus of information processing and regulation in the
brain. Reflecting this central role, ACC is structurally and functionally heterogeneous, a fact …

In the absence of any overt task performance, it has been shown that spontaneous, intrinsic
brain activity is expressed as systemwide, resting-state networks in the adult brain. However …
