Abstract Theory of mind (ie, the ability to infer others' mental states)–a fundamental social
cognitive ability–declines with increasing age. Prior investigations have focused on …

Functional imaging studies have shown that certain brain regions, including posterior
cingulate cortex (PCC) and ventral anterior cingulate cortex (vACC), consistently show …

The electrophysiological basis for higher brain activity during rest and internally directed
cognition within the human default mode network (DMN) remains largely unknown. Here we …

A growing number of studies suggest the brain's “default network” becomes engaged when
individuals recall their personal past or simulate their future. Recent reports of heterogeneity …

The brain's default network (DN) has been a topic of considerable empirical interest. In fMRI
research, DN activity is associated with spontaneous and self‐generated cognition, such as …

The default mode network (DMN) has been mostly investigated using positron emission
tomography and functional magnetic resonance imaging (fMRI) and has received mixed …

We used a semantic feature-matching task combined with multivoxel pattern decoding to test
contrasting accounts of the role of the default mode network (DMN) in cognitive flexibility. By …

The default network is involved in self-generated thought, a class of cognition that includes
autobiographical memory, prospection, and reasoning about the mental states of others. We …

The human default mode network (DMN) is engaged at rest and in cognitive states such as
self-directed thoughts. Interconnected homologous cortical areas in primates constitute a …

Anticorrelation between the default network (DN) and dorsal attention network (DAN) is
thought to be an intrinsic aspect of functional brain organization reflecting competing …
