Dysmaturation of the default mode network in autism

Human Brain Mapping, 2013
Two hypotheses of autism spectrum disorder (ASD) propose that this condition is characterized by deficits in Theory of Mind and by hypoconnectivity between remote cortical regions with hyperconnectivity locally. The default mode network (DMN) is a set of remote, functionally connected cortical nodes less active during executive tasks than at rest and ...

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.

Default mode network activity in depression subtypes

Reviews in the Neurosciences, 2021
Abstract Depression continues to carry a major disease burden worldwide, with limitations on the success of traditional pharmacological or psychological treatments. Recent approaches have therefore focused upon the neurobiological underpinnings of depression, and on the “individualization” of depression symptom profiles.

Amyloid-driven disruption of default mode network connectivity in cognitively healthy individuals [PDF]

Brain Communications, 2021
Cortical accumulation of amyloid beta is one of the first events of Alzheimer's disease pathophysiology, and has been suggested to follow a consistent spatiotemporal ordering, starting in the posterior cingulate cortex, precuneus and medio-orbitofrontal ...

Fluctuations between high- and low-modularity topology in time-resolved functional connectivity [PDF]

NeuroImage, vol. 180, pp. 406-416, 2018, 2017
Modularity is an important topological attribute for functional brain networks. Recent studies have reported that modularity of functional networks varies not only across individuals being related to demographics and cognitive performance, but also ...

Default mode network in the effects of Δ9-Tetrahydrocannabinol (THC) on human executive function. [PDF]

PLoS ONE, 2013
Evidence is increasing for involvement of the endocannabinoid system in cognitive functions including attention and executive function, as well as in psychiatric disorders characterized by cognitive deficits, such as schizophrenia.

Recruitment of the default mode network during a demanding act of executive control. [PDF]

eLife, 2015
In the human brain, a default mode or task-negative network shows reduced activity during many cognitive tasks and is often associated with internally-directed processes, such as mind wandering and thoughts about the self.

The default mode network is affected in the early stage of simian immunodeficiency virus infection: a longitudinal study

Neural Regeneration Research, 2023
Acquired immune deficiency syndrome infection can lead to cognitive dysfunction represented by changes in the default mode network. Most recent studies have been cross-sectional and thus have not revealed dynamic changes in the default mode network ...

The default mode network and rumination in individuals at risk for depression

Social Cognitive and Affective Neuroscience, 2023
The default mode network (DMN) is a network of brain regions active during rest and self-referential thinking. Individuals with major depressive disorder (MDD) show increased or decreased DMN activity relative to controls. DMN activity has been linked to

The Default Mode Network in Autism [PDF]

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 2017
Autism spectrum disorder (ASD) is characterized by deficits in social communication and interaction. Since its discovery as a major functional brain system, the default mode network (DMN) has been implicated in a number of psychiatric disorders, including ASD.
