Transcranial stimulation of alpha oscillations up-regulates the default mode network
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance In the brain’s functional organization, the default mode network (DMN) represents a key architecture, whose dysregulation is involved in a host of major neuropsychiatric disorders.

Default mode network activity in bipolar disorder [PDF]
Epidemiology and Psychiatric Sciences, 2020 Abstract Since its discovery in 1997, the default mode network (DMN) and its components have been extensively studied in both healthy individuals and psychiatric patients. Several studies have investigated possible DMN alterations in specific mental conditions such as bipolar disorder (BD).

The Default Mode Network and the Problem of Determining Intrinsic Mental Contents
Studies in Logic, Grammar and Rhetoric, 2015 We provide a brief overview of the shift toward the intrinsic view of brain activity, describing in particular the structural and functional connectivity patterns of the “Default mode network” (part I).

Involvement of the default mode network under varying levels of cognitive effort
Scientific Reports, 2022 Everyday cognitive functioning is characterized by constant alternations between different modes of information processing, driven by constant fluctuations in environmental demands.

Episodic memory retrieval, parietal cortex, and the default mode network: Functional and topographic analyses [PDF]
, 2011 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).

Controllability of structural brain networks. [PDF]
, 2015 Cognitive function is driven by dynamic interactions between large-scale neural circuits or networks, enabling behaviour. However, fundamental principles constraining these dynamic network processes have remained elusive.

Emotional faces and the default mode network [PDF]
Neuroscience Letters, 2012 The default-mode network (DMN) of the human brain has become a central topic of cognitive neuroscience research. Although alterations in its resting state activity and in its recruitment during tasks have been reported for several mental and neurodegenerative disorders, its role in emotion processing has received relatively little attention.

Age differences in default mode activity on easy and difficult spatial judgment tasks
Frontiers in Human Neuroscience, 2010 The default network is a system of brain areas that are engaged when the mind is not involved in goal-directed activity. Most previous studies of age-related changes in default mode processing have used verbal tasks.

Long reaction times are associated with delayed brain activity in Lewy body dementia [PDF]
, 2018 A significant symptom of Lewy body dementia (LBD) is slow cognitive processing or bradyphrenia. In a previous fMRI task-based study, we found slower responses in LBD, accompanied by greater deactivation in the default mode network.

Resting-state modulation of alpha rhythms by interference with angular gyrus activity [PDF]
, 2014 The default mode network is active during restful wakefulness and suppressed during goal-driven behavior. We hypothesize that inhibitory interference with spontaneous ongoing, that is, not task-driven, activity in the angular gyrus (AG), one of the core ...
