Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Functional connectivity within the default mode network in patients with major depressive disorder has been frequently reported to be abnormal but with contradicting directions in previous studies with small sample sizes.

The Surprising Role of the Default Mode Network [PDF]
, 2020 AbstractThe default mode network (DMN) is a group of high-order brain regions recently implicated in processing external naturalistic events, yet it remains unclear what cognitive function it serves. Here we identified the cognitive states predictive of DMN fMRI coactivation.

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.

Default Mode Network alterations in alexithymia: An EEG power spectra and connectivity study [PDF]
, 2016 Recent neuroimaging studies have shown that alexithymia is characterized by functional alterations in different brain areas [e.g., posterior cingulate cortex (PCC)], during emotional/social tasks.

Nature Communications, 2017 It is not known exactly where amyloid-β (Aβ) fibrils begin to accumulate in individuals with Alzheimer’s disease (AD). Recently, we showed that abnormal levels of Aβ42 in cerebrospinal fluid (CSF) can be detected before abnormal amyloid can be detected ...

Study on Intelligent Forecasting of Credit Bond Default Risk [PDF]
arXiv, 2023 Credit risk in the China's bond market has become increasingly evident, creating a progressively escalating risk of default for credit bond investors. Given the current incomplete and inaccurate bond information disclosure, timely tracking and forecasting the individual credit bond default risks have become essential to maintain market stability and ...

Dark control: The default mode network as a reinforcement learning agent
Human Brain Mapping, 2020 The default mode network (DMN) is believed to subserve the baseline mental activity in humans. Its higher energy consumption compared to other brain networks and its intimate coupling with conscious awareness are both pointing to an unknown overarching ...
