Medial prefrontal decoupling from the default mode network benefits memory

N.C.J. Müller, Martin Dresler, G. Janzen et al. preprint

Abstract In the last few years the involvement of the medial prefrontal cortex (mPFC) in memory processing has received increased attention. It is centrally involved when we use prior knowledge (schemas) to improve learning of new material. With the mPFC also being one of the core hubs of the default mode network (DMN) and the DMN’s role in memory retrieval, we decided to investigate whether...

Default Mode Network Detection using EEG in Real-time

Navin Cooray, Chetan Gohil, Brendan Harris et al. preprint

Abstract Mental health disorders affect countless people worldwide and present a major challenge for mental health services, which are struggling with the demand on a global scale. Recent studies have indicated that activity of the brain’s Default Mode Network (DMN) could prove insightful in monitoring patient recovery from depression and has been used as a therapeutic target itself. An...

Default mode network-basal ganglia network connectivity predicts the transition to postherpetic neuralgia

Ying Wu, Chao Wang, Wei Qian et al. preprint

Abstract Background Neuroimaging study has revealed aberrant network functional connectivities in postherpetic neuralgia (PHN) patients. However, there is a lack of knowledge regarding the relationship between brain network connectivity in acute period and disease prognosis. The purpose was to detect a characteristic network connectivity in the process of herpes zoster (HZ) pain chronification...

Disruptions of default mode network and precuneus connectivity associated with cognitive dysfunctions in tinnitus

Stephanie Rosemann, Josef P. Rauschecker preprint

Tinnitus is the perception of a ringing, buzzing or hissing sound “in the ear” without external stimulation. Previous research has demonstrated changes in resting-state functional connectivity in tinnitus, but findings do not overlap and are even contradictory. Furthermore, how altered functional connectivity in tinnitus is related to cognitive abilities is currently unknown. Here we...

Increased Default Mode Network Connectivity and Temperament Predict Internalizing Symptoms in Early Childhood

Halle Miller, Johanna Chajes, Tobias Grossmann preprint

Abstract This study investigates the early neural and temperament precursors to internalizing psychopathology. Increased default mode network (DMN) functional connectivity and decreased frontoparietal network (FPN) connectivity are established neural signatures of internalizing disorders in adults, but it is unknown if these patterns represent early-emerging vulnerability. In a community sample...

Oscillatory default mode network coupling in concussion

B.T Dunkley, Karolina Urban, L. Da Costa et al. preprint

Abstract Background Concussion is a common form of mild traumatic brain injury (mTBI). Despite the descriptor ‘mild’, a single injury can leave long-lasting and sustained alterations to brain function, including changes to localised activity and large-scale interregional communication. Cognitive complaints are thought to arise from such functional deficits. We investigated the impact of injury...

Default Mode Network activation at task switches reflects mental task-set structure

Ashley X. Zhou, John Duncan, Daniel J Mitchell preprint

Abstract Recent findings challenge traditional views of the Default Mode Network (DMN) as purely task-negative or self-oriented, showing increased DMN activity during demanding switches between externally-focused tasks (Crittenden et al., 2015; Smith et al., 2018; Zhou et al., 2024). However, it is unclear what modulates the DMN at switches, with transitions within a stimulus domain activating...

Modulatory Interactions between the Default Mode Network and Task Positive Networks in Resting-State

Xin Di, Bharat B. Biswal

Communications between different brain systems are critical to support complex brain functions. Unlike generally high functional connectivity between brain regions from same system, functional connectivity between regions from different systems are more variable. In the present study, we examined whether the connectivity between different brain networks were modulated by other regions by using...

Medial Temporal Default Mode Network Selectively Encodes Autobiographical Visual Imagery

Andrew J. Anderson, Adam Turnbull, Feng V. Lin preprint

Abstract The human brain’s capacity to imagine visual scenes from memory is thought to rely on the medial temporal subsystem of the default mode network (MT-DMN), yet the neural codes supporting this ability remain poorly understood. We combined functional magnetic resonance imaging (fMRI) with vision and language artificial intelligence models to characterize neural codes during...
