    Uncovering circuit mechanisms of current sinks and sources with biophysical simulations of primary visual cortex

    Atle E Rimehaug, Alexander J Stasik ... Anton Arkhipov
    A biophysically detailed model of mouse primary visual cortex reproduces, in a quantitative manner, experimentally recorded spikes and local field potentials, and suggests mechanisms that form current sinks and sources in vivo.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst, Susan R Strickler ... Georg Jander
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Brain endothelial cell TRPA1 channels initiate neurovascular coupling

    Pratish Thakore, Michael G Alvarado ... Scott Earley
    Activation of TRPA1 channels on cerebral capillary endothelial cells initiates a retrograde signal that propagates and dilates upstream arterioles.

    First spikes in visual cortex enable perceptual discrimination

    Arbora Resulaj, Sarah Ruediger ... Massimo Scanziani
    A brief time window of visually evoked activity in mouse primary visual cortex is sufficient for perceptual discrimination.

    Dendritic spikes in hippocampal granule cells are necessary for long-term potentiation at the perforant path synapse

    Sooyun Kim, Yoonsub Kim ... Won-Kyung Ho
    A novel mechanism of local plasticity in the distal dendrites of hippocampal granule cells.

    Experiments from unfinished Registered Reports in the Reproducibility Project: Cancer Biology

    Timothy M Errington, Alexandria Denis ... Lisa Young
    A project to repeat experiments from high-impact papers in cancer biology did not complete all replications, with challenges ranging from mundane reasons to unexpected methodological issues.

    Bidirectional synaptic plasticity rapidly modifies hippocampal representations

    Aaron D Milstein, Yiding Li ... Sandro Romani
    Dendritic calcium spikes translocate hippocampal place fields by inducing a non-Hebbian form of bidirectional synaptic plasticity that operates over a seconds-long timescale called behavioral timescale synaptic plasticity.

    Molecular organization and dynamics of the fusion protein Gc at the hantavirus surface

    Eduardo A Bignon, Amelina Albornoz ... Nicole D Tischler
    Hantavirus spikes are related laterally by 2-fold Gc contacts that can be disulfide-linked and display a temperature-dependent dynamic behavior at neutral pH, exposing and masking the Gc fusion loops.

    Protein engineering expands the effector recognition profile of a rice NLR immune receptor

    Juan Carlos De la Concepcion, Marina Franceschetti ... Mark J Banfield
    Structure-led protein engineering can expand the effector recognition profile of plant intracellular NLR immune receptors, providing a proof-of-principle for the development of novel disease resistance mechanisms in plants.

    Inferring synaptic inputs from spikes with a conductance-based neural encoding model

    Kenneth W Latimer, Fred Rieke, Jonathan W Pillow
    The conductance-based encoding model creates a new bridge between statistical models and biophysical models of neurons, and infers visually-evoked excitatory and inhibitory synaptic conductances from spike trains in macaque retina.
