    A statistical framework to assess cross-frequency coupling while accounting for confounding analysis effects

    Jessica K Nadalin, Louis-Emmanuel Martinet ... Mark A Kramer
    A new measure for cross-frequency coupling assesses phase-amplitude coupling and amplitude-amplitude coupling, and accounts for confounding factors such as low-frequency amplitude fluctuations, using a flexible statistical modeling approach.

    More homogeneous capillary flow and oxygenation in deeper cortical layers correlate with increased oxygen extraction

    Baoqiang Li, Tatiana V Esipova ... Sava Sakadžić
    Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

    Bridging the gap between single-cell migration and collective dynamics

    Florian Thüroff, Andriy Goychuk ... Erwin Frey
    A computational model, based on single-cell features like contractility and polarizability, quantitatively describes cellular dynamics from the single cell level up to small cohorts and confluent tissues.

    Mapping circuit dynamics during function and dysfunction

    Srinivas Gorur-Shandilya, Elizabeth M Cronin ... Eve Marder
    Mapping spike patterns from a small identified circuit reveals the diversity and complexity of circuit dynamics across animals and in response to perturbations.
    1. Neuroscience

    Reinforcement biases subsequent perceptual decisions when confidence is low, a widespread behavioral phenomenon

    Armin Lak, Emily Hueske ... Adam Kepecs
    Confidence-dependent reinforcement learning is active and produces trial-to-trial choice updating even in well-learned perceptual decisions without explicit reward biases, across species and sensory modalities.

    A synergy-based hand control is encoded in human motor cortical areas

    Andrea Leo, Giacomo Handjaras ... Emiliano Ricciardi
    The human brain encodes coordinated patterns of joint movements – synergies – to increase the efficiency with which it can control complex hand movements.

    Consistent patterns of distractor effects during decision making

    Bolton KH Chau, Chun-Kit Law ... Matthew FS Rushworth
    The value of any choice is not static but dynamically changes as a function of the context of the alternatives even if they are seemingly irrelevant.

    Lotka-Volterra pairwise modeling fails to capture diverse pairwise microbial interactions

    Babak Momeni, Li Xie, Wenying Shou
    With mathematical modeling being an important source of insight for microbial communities, we may need to move beyond commonly-used pairwise models that do not capture microbial interactions.

    An arbitrary-spectrum spatial visual stimulator for vision research

    Katrin Franke, André Maia Chagas ... Thomas Euler
    Towards a community effort, we here present a flexible yet standardised visual stimulator design based on open hardware and software.

    A locally-blazed ant trail achieves efficient collective navigation despite limited information

    Ehud Fonio, Yael Heyman ... Ofer Feinerman
    Ants employ a new kind of trail to resolve group-level navigational difficulties in scenarios where the information available to individuals does not suffice.
