The default mode network (DMN) is often considered a functionally homogeneous system that is broadly associated with internally directed cognition (e.g., episodic memory, theory of mind, self-evaluation). However, few studies have examined how this network interacts with other networks during putative "default" processes such as episodic memory retrieval. Using functional magnetic resonance...
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 particular challenge. Many suspect that left unconstrained, its activity will vary unpredictably. Despite this prediction we identify a baseline state of the normal adult human brain in terms of the brain oxygen...
Over the years, there have been numerous accounts of the events involved in the discovery of the default mode network (DMN), but as different accounts have multiplied and the DMN has surfaced in the popular media, a misconception has crept into a part of that history concerning the 1997 metaanalysis that identified the common brain regions that are deactivated by visual tasks and comprise the...
