    Processing of different spatial scales in the human brain

    Michael Peer, Yorai Ron ... Shahar Arzy
    When subjects perform spatial judgments in environments of increasing scale, brain activity shifts along posterior-anterior gradients, advancing from the visual system to the default-mode network.

    A stochastic neuronal model predicts random search behaviors at multiple spatial scales in C. elegans

    William M Roberts, Steven B Augustine ... Shawn R Lockery
    A stochastic model of locomotory control in C. elegans based on an extensive new set of tracking data can explain and predict effects of ablations and mutations on behavior.

    A geometric attractor mechanism for self-organization of entorhinal grid modules

    Louis Kang, Vijay Balasubramanian
    The hierarchy of entorhinal grid cell modules with constant scale ratios can self-organize through a new geometrically organized attractor mechanism.

    Gigapixel imaging with a novel multi-camera array microscope

    Eric E Thomson, Mark Harfouche ... Eva A Naumann
    A new multi camera imaging platform simultaneously captures large-area, high-resolution video of unconstrained small model organisms and provides behavioral measurements that span multiple spatial scales.

    Spatial Navigation: A question of scale

    Muireann Irish, Siddharth Ramanan
    An fMRI experiment reveals distinct brain regions that respond in a graded manner as humans process distance information across increasing spatial scales.

    Broad geographic sampling reveals the shared basis and environmental correlates of seasonal adaptation in Drosophila

    Heather E Machado, Alan O Bergland ... Dmitri A Petrov
    Seasonal selection is a general feature of Drosophila melanogaster genetic variation, occurring in North American and European populations and affecting large proportions of the genome.

    Three-dimensional single-cell transcriptome imaging of thick tissues

    Rongxin Fang, Aaron Halpern ... Xiaowei Zhuang
    By integrating multiplexed error-robust fluorescence in situ hybridization (MERFISH), deep learning, optical sectioning, and protocol optimization, thick-tissue 3D MERFISH allows volumetric single-cell transcriptome imaging of thick-tissue samples, broadening the scope of applications of spatial genomics.

    Structural development and dorsoventral maturation of the medial entorhinal cortex

    Saikat Ray, Michael Brecht
    The medial entorhinal cortex is important for spatial memory formation and matures from dorsal, where smaller spatial-scales are represented, to ventral, where larger spatial-scales are represented.

    Irregular spiking of pyramidal neurons organizes as scale-invariant neuronal avalanches in the awake state

    Timothy Bellay, Andreas Klaus ... Dietmar Plenz
    Spontaneous, irregular spiking in single cortical pyramidal neurons assembles as neuronal avalanches at the group level identifying a robust scale-invariant organization of resting activity in the awake state.

    Linking spatial patterns of terrestrial herbivore community structure to trophic interactions

    Jakub Witold Bubnicki, Marcin Churski ... Dries PJ Kuijper
    The spatial interactions between humans, large carnivores and herbivores cascade down in a complex but predictable way to lower trophic levels affecting regeneration of tree species in a temperate forest.
