    Human VMPFC encodes early signatures of confidence in perceptual decisions

    Sabina Gherman, Marios G. Philiastides
    Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

    Localization of spontaneous bursting neuronal activity in the preterm human brain with simultaneous EEG-fMRI

    Tomoki Arichi, Kimberley Whitehead ... Lorenzo Fabrizi
    Direct measure of neural and hemodynamic activity in the developing human brain shows that the insula is a major source of transient bursting events that are critical for cortical maturation.

    Inferring multi-scale neural mechanisms with brain network modelling

    Michael Schirner, Anthony Randal McIntosh ... Petra Ritter
    Hybrid brain network models predict neurophysiological processes that link structural and functional empirical data across scales and modalities in order to better understand neural information processing and its relation to brain function.

    The transformation of sensory to perceptual braille letter representations in the visually deprived brain

    Marleen Haupt, Monika Graumann ... Radoslaw Cichy
    The visually deprived brain processes sensory letter information in tactile areas but perceptual letter information in sighted reading areas, revealing experience-dependent brain plasticity.

    EEG-fMRI in awake rat and whole-brain simulations show decreased brain responsiveness to sensory stimulations during absence seizures

    Petteri Stenroos, Isabelle Guillemain ... Emmanuel L Barbier
    Rats with absence epilepsy exhibit hindered and restricted sensory processing during ongoing seizures, as demonstrated by functional magnetic resonance imaging and mean-field simulation studies.

    Alpha/beta power decreases track the fidelity of stimulus-specific information

    Benjamin James Griffiths, Stephen D Mayhew ... Simon Hanslmayr
    Neural representations of stimulus-specific information increase in fidelity as the power of alpha/beta activity decreases, suggesting that alpha/beta power decreases reflect a domain-general mechanism that supports information representation.

    Combining magnetoencephalography with magnetic resonance imaging enhances learning of surrogate-biomarkers

    Denis A Engemann, Oleh Kozynets ... Alexandre Gramfort
    Predicting age jointly from multimodal brain images and electrophysiology with machine learning enhances detecting health issues and facets of cognitive decline.

    Spatial signatures of anesthesia-induced burst-suppression differ between primates and rodents

    Nikoloz Sirmpilatze, Judith Mylius ... Susann Boretius
    Functional imaging (fMRI) across four mammalian species maps the brain areas engaging in burst-suppression activity during anesthesia, and uncovers differences between primates and rodents.

    The causal role of the somatosensory cortex in prosocial behaviour

    Selene Gallo, Riccardo Paracampo ... Valeria Gazzola
    A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.
    1. Neuroscience

    TMS-evoked responses are driven by recurrent large-scale network dynamics

    Davide Momi, Zheng Wang, John D Griffiths
    Whole-brain computational modelling, incorporating novel ML-based parameter estimation techniques, reveals how transcranial magnetic stimulation-evoked brain responses are driven at earlier timepoints by local echoes of the external stimulus, and at later timepoints by large-scale network reverberation across the connectome.
