    Structured inhibitory activity dynamics in new virtual environments

    Moises Arriaga, Edward B Han
    Inhibitory interneuron activity is dynamically modulated in new environments while individual interneurons show consistent levels of activity modulation across multiple environments, suggesting functional specialization of inhibitory subnetworks.

    Novel long-range inhibitory nNOS-expressing hippocampal cells

    Zoé Christenson Wick et al.
    An intersectional genetic vector approach allows the identification and characterization of novel hippocampal inhibitory neurons with both broad local connectivity within CA1 and long-range projections to several extrahippocampal areas.

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

    Jessica K Nadalin et al.
    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.

    A neural mechanism for contextualizing fragmented inputs during naturalistic vision

    Daniel Kaiser et al.
    In scene-selective occipital cortex and within 200 ms of processing, visual inputs are sorted according to their typical spatial position within a scene.

    An arbitrary-spectrum spatial visual stimulator for vision research

    Katrin Franke et al.
    Towards a community effort, we here present a flexible yet standardised visual stimulator design based on open hardware and software.

    Presenilin/γ-secretase-dependent EphA3 processing mediates axon elongation through non-muscle myosin IIA

    Míriam Javier-Torrent et al.
    EphA signaling plays dual opposite roles on axon dynamics in neurons, so it inhibits and promotes axon growth through ligand binding and receptor processing, respectively.

    Size control of the inner ear via hydraulic feedback

    Kishore R Mosaliganti et al.
    Size regulation of the otic vesicle, the progenitor of the inner ear, is mediated by mechanical feedback involving fluid influx, hydraulic pressure, and tissue mechanics.

    The NKCC1 antagonist bumetanide mitigates interneuronopathy associated with ethanol exposure in utero

    Alexander GJ Skorput et al.
    Prenatal ethanol exposure results in aberrant tangential migration by altering NKCC1-mediated chloride homeostasis that can be mitigated by bumetanide.

    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.

    Processing of different spatial scales in the human brain

    Michael Peer et al.
    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.
