    27 T ultra-high static magnetic field changes orientation and morphology of mitotic spindles in human cells

    Lei Zhang, Yubin Hou ... Xin Zhang
    An ultra-high static magnetic field changes mitotic spindle orientation in cells by exerting magnetic torques on both microtubules and chromosomes.

    Co-movement of astral microtubules, organelles and F-actin by dynein and actomyosin forces in frog egg cytoplasm

    James F Pelletier, Christine M Field ... Timothy J Mitchison
    Live imaging of multiple cytoplasmic networks in frog egg extracts calls for new models for how egg cytoplasm is physically organized during cleavage divisions.

    Plant secondary metabolite-dependent plant-soil feedbacks can improve crop yield in the field

    Valentin Gfeller, Jan Waelchli ... Matthias Erb
    A 2-year field experiment reveals that plant secondary metabolites can be harnessed to increase crop productivity through plant-soil feedbacks under agronomically realistic conditions.

    Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field

    Arne Weinhold, Elham Karimi Dorcheh ... Ian T Baldwin
    The attempt to manipulate a microbiome in planta to study the ecological consequences under field conditions leaves plants and their microbes surprisingly unimpressed.

    The aperiodic exponent of subthalamic field potentials reflects excitation/inhibition balance in Parkinsonism

    Christoph Wiest, Flavie Torrecillos ... Huiling Tan
    The slope of the power spectrum of subthalamic local field potentials tracks pathological states in Parkinson’s disease and likely complements beta activity as a feedback marker for adaptive deep brain stimulation.

    Cortical waves mediate the cellular response to electric fields

    Qixin Yang, Yuchuan Miao ... Wolfgang Losert
    Electrical and biomechanical stimuli directly bias cortical signal transduction and cytoskeletal waves, and the direct bias induced by an electric field develops slowly compared to the rapid surface-receptor-mediated response to chemotactic gradients.

    Local field potentials reflect cortical population dynamics in a region-specific and frequency-dependent manner

    Cecilia Gallego-Carracedo, Matthew G Perich ... Juan Álvaro Gallego
    There is a frequency-dependent association between the local field potential and the coordinated activity of populations of single neurons, which remains constant during different aspects of behaviour but changes across regions of primate sensorimotor cortex.

    Oligodendrocyte-mediated myelin plasticity and its role in neural synchronization

    Sinisa Pajevic, Dietmar Plenz ... R Douglas Fields
    A biologically plausible model of myelin plasticity demonstrates how oligodendrocytes can selectively adjust conduction delays in axon bundles to allow robust communication between brain regions through long-range synchronization.

    Electric field causes volumetric changes in the human brain

    Miklos Argyelan, Leif Oltedal ... Christopher Abbott
    The electroconvulsive therapy induced electric field magnitude and laterality is related to volumetric increases in cortical and subcortical structures, but the association with clinical outcomes remains elusive.

    Enhancing precision in human neuroscience

    Stephan Nebe, Mario Reutter ... Gordon B Feld
    Measurement precision offers a comprehensive perspective on good scientific practices to improve reproducibility of research results by providing means to optimize design and analysis parameters (e.g. sample size, trial count, or sample heterogeneity) in accordance with the researcher’s goals.
