    Recruitment of the default mode network during a demanding act of executive control

    Ben M Crittenden, Daniel J Mitchell, John Duncan
    The default mode network in the brain is activated during the performance of executive-type tasks when a substantial change in cognitive contents is required.
    1. Neuroscience

    Task-evoked metabolic demands of the posteromedial default mode network are shaped by dorsal attention and frontoparietal control networks

    Godber M Godbersen, Sebastian Klug ... Andreas Hahn
    In the human brain, default mode network BOLD deactivations can be accompanied by both increases and decreases in glucose metabolism, depending on the respective metabolic demands of task-positive cognitive control and attention networks.
    1. Neuroscience

    Infant brain regional cerebral blood flow increases supporting emergence of the default-mode network

    Qinlin Yu, Minhui Ouyang ... Hao Huang
    Unprecedented 4D spatiotemporal infant regional cerebral blood flow framework and region-specific physiology–function coupling across infancy were elucidated, highlighting strong physiology–function coupling specifically at the default-mode network to meet extraneuronal metabolic demand for network emergence.
    1. Neuroscience

    Content-specific activity in frontoparietal and default-mode networks during prior-guided visual perception

    Carlos González-García, Matthew W Flounders ... Biyu J He
    Prior experience alters content-specific neural representations of visual input in frontoparietal and default-mode networks.
    1. Neuroscience

    Default mode-visual network hypoconnectivity in an autism subtype with pronounced social visual engagement difficulties

    Michael V Lombardo, Lisa Eyler ... Karen Pierce
    Functional hypoconnectivity between ‘social brain’ default mode circuitry and visual association cortex underpins a subtype of autistic toddlers with a strong preference to attend to the non-social visual world.
    1. Neuroscience

    Perceptual coupling and decoupling of the default mode network during mind-wandering and reading

    Meichao Zhang, Boris C Bernhardt ... Elizabeth Jefferies
    Functional neuroimaging in the human brain reveals the neurocognitive mechanisms that underpin the experience of mind-wandering during reading, explaining why comprehension is impaired.
    1. Neuroscience

    Electrophysiological dynamics of salience, default mode, and frontoparietal networks during episodic memory formation and recall revealed through multi-experiment iEEG replication

    Anup Das, Vinod Menon
    Human intracranial electroencephalography recordings across 177 participants and four diverse episodic memory experiments demonstrate how the anterior insula node of the salience network orchestrates dynamics of large-scale brain networks.
    1. Neuroscience

    A double dissociation between semantic and spatial cognition in visual to default network pathways

    Tirso RJ Gonzalez Alam, Katya Krieger-Redwood ... Elizabeth Jefferies
    Default mode network and visual cortex are connected via two parallel pathways that differentially respond to the processing of visual scenes and semantic information about objects, reflecting domain-specific organisation.
    1. Neuroscience

    Neural representations of naturalistic events are updated as our understanding of the past changes

    Asieh Zadbood, Samuel Nastase ... Uri Hasson
    Changes in the interpretation of specific scenes in a narrative trigger corresponding updates in the neural patterns evoked by those scenes in the default mode network.
    1. Neuroscience

    Large-scale neural dynamics in a shared low-dimensional state space reflect cognitive and attentional dynamics

    Hayoung Song, Won Mok Shim, Monica D Rosenberg
    People’s neural activity travels between a small number of brain states based on what they are thinking and paying attention to.
