Discoveries over the past two decades demonstrate that regions distributed throughout the
association cortex, often called the default network, are suppressed during tasks that …

Many human brain disorders are associated with characteristic alterations in the structural

Psychiatric disorders encompass complex aberrations of cognition and affect and are
among the most debilitating and poorly understood of any medical condition. Current …

Most research on mind-wandering has characterized it as a mental state with contents that
are task unrelated or stimulus independent. However, the dynamics of mind-wandering …

Aberrant patterns of brain functional connectivity in the default mode network (DMN) have

Cognitive function requires the coordination of neural activity across many scales, from
neurons and circuits to large-scale networks. As such, it is unlikely that an explanatory …

Many mental illnesses share overlapping or similar clinical symptoms, confounding the
