    Spatial cell firing during virtual navigation of open arenas by head-restrained mice

    Guifen Chen, John Andrew King ... Neil Burgess
    A mouse virtual reality system is presented which allows normal spatial behavior and place, grid and head-direction cell firing patterns in 2-D arenas, and is compatible with electrophysiology and multi-photon imaging.

    1. Neuroscience

    Asymmetric ON-OFF processing of visual motion cancels variability induced by the structure of natural scenes

    Juyue Chen, Holly B Mandel ... Damon A Clark
    The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.

    Chronic postnatal chemogenetic activation of forebrain excitatory neurons evokes persistent changes in mood behavior

    Sthitapranjya Pati, Kamal Saba ... Vidita A Vaidya
    Enhanced Gq-signaling-mediated activation of forebrain excitatory neurons in postnatal life programs enhanced anxiety-, despair- and schizophrenia-like behavior, recapitulating key aspects of the behavioral consequences of early life adversity.

    Gjd2b-mediated gap junctions promote glutamatergic synapse formation and dendritic elaboration in Purkinje neurons

    Sahana Sitaraman, Gnaneshwar Yadav ... Vatsala Thirumalai
    A protein that is a building block of intercellular bridges between neurons promotes their ability to grow dendrites and make synapses.

    Glutamate is required for depression but not potentiation of long-term presynaptic function

    Zahid Padamsey, Rudi Tong, Nigel Emptage
    Electrophysiological and optical analysis of neurotransmitter release at central synapses reveals that glutamate signalling is not required for the long-term potentiation (LTP) of presynaptic function, and instead only promotes presynaptic long-term depression (LTD).

    Bacterial death and TRADD-N domains help define novel apoptosis and immunity mechanisms shared by prokaryotes and metazoans

    Gurmeet Kaur, Lakshminarayan M Iyer ... L Aravind
    Prokaryotic TRADD-N and Death-like adaptor domains in diverse predicted apoptosis and immune systems from multicellular prokaryotes and metazoans indicate the common origin of key apoptosis mechanisms required for the stabilization of multicellularity.

    Amplitude modulations of cortical sensory responses in pulsatile evidence accumulation

    Sue Ann Koay, Stephan Thiberge ... David W Tank
    From as early as primary visual cortex and across posterior cortical areas, neural responses to visual pulses during an evidence-accumulation task exhibit a multitude of task-related amplitude modulations/gain changes.

    An inhibitory gate for state transition in cortex

    Stefano Zucca, Giulia D’Urso ... Tommaso Fellin
    Two major subtypes of cortical interneurons, the PV and the SST positive cells, causally contribute to the regulation of large-scale state transitions in the cortex.

    A fully automated high-throughput workflow for 3D-based chemical screening in human midbrain organoids

    Henrik Renner, Martha Grabos ... Jan M Bruder
    Automated liquid handling, whole mount staining, and clearing allow unbiased 3D quantitation of cell markers in human neural organoids with diameters of up to 1 mm at the single-cell level.
