    Distinct roles of forward and backward alpha-band waves in spatial visual attention

    Andrea Alamia, Lucie Terral ... Rufin VanRullen
    Covert visual attention modulates alpha-band traveling waves propagating from frontal to occipital regions in both hemispheres, yet it modulates waves propagating in the opposite direction (occipital to frontal) only in the presence of visual stimulation.

    Novel cyclic homogeneous oscillation detection method for high accuracy and specific characterization of neural dynamics

    Hohyun Cho, Markus Adamek ... Peter Brunner
    Detecting neural oscillations in time and frequency domains enables the detailed study of spatiotemporal dynamics of oscillations throughout the brain and the investigation of biomarkers that index functional brain areas.

    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.
    1. Neuroscience

    Multiple mechanisms link prestimulus neural oscillations to sensory responses

    Luca Iemi, Niko A Busch ... Vadim V Nikulin
    Neural oscillations prior to a stimulus modulate the strength of early and late responses in opposite directions via distinct mechanisms.

    Age-dependent electroencephalogram (EEG) patterns during sevoflurane general anesthesia in infants

    Laura Cornelissen, Seong-Eun Kim ... Charles B Berde
    Alpha EEG oscillations emerge at 4 months of age during sevoflurane general anesthesia, and unlike in adults, have a widespread spatial distribution that likely reflects differences in brain development.

    A state space modeling approach to real-time phase estimation

    Anirudh Wodeyar, Mark Schatza ... Mark A Kramer
    A statistically principled approach developed to estimate phase of rhythmic signals in real-time shows robustness to multiple sources of error and also provides confidence criteria.

    Sleep spindle maturity promotes slow oscillation-spindle coupling across child and adolescent development

    Ann-Kathrin Joechner, Michael A Hahn ... Markus Werkle-Bergner
    Across four samples of children, adolescents, and young adults, age-related higher similarity of dominant, development-specific fast sleep spindles and adult-like fast sleep spindles is uniquely related to stronger and more precise slow oscillation-sleep spindle coupling.

    Event-related modulation of alpha rhythm explains the auditory P300-evoked response in EEG

    Alina Studenova, Carina Forster ... Vadim Nikulin
    The decrease in alpha rhythm amplitude in the parietal regions after the presentation of a deviant auditory stimulus gives rise to a part of the P300-evoked response.

    On cross-frequency phase-phase coupling between theta and gamma oscillations in the hippocampus

    Robson Scheffer-Teixeira, Adriano BL Tort
    Phase-locking of hippocampal theta and gamma waves has been proposed to support memory formation, but an analysis using robust statistical methods finds no convincing evidence for the phenomenon.

    Slow oscillation-spindle coupling predicts enhanced memory formation from childhood to adolescence

    Michael A Hahn, Dominik Heib ... Randolph F Helfrich
    An individualized cross-frequency coupling approach identified slow oscillation-spindle coupling strength as a novel mechanism that mediates memory formation during cortical maturation.
