    1. Neuroscience

    Toolkits for detailed and high-throughput interrogation of synapses in C. elegans

    Maryam Majeed, Haejun Han ... Hang Lu
    An imaging pipeline together with a collection of transgenic nematode strains provide a strategy to visualize and properly quantify synaptic connectivity in the C. elegans brain.
    1. Neuroscience

    High-throughput microcircuit analysis of individual human brains through next-generation multineuron patch-clamp

    Yangfan Peng, Franz Xaver Mittermaier ... Jörg Rolf Paul Geiger
    Combining a multineuron patch-clamp system with an automated pipette pressure and cleaning device enables efficient screening of synaptic connectivity in human brain slices and allows inter-individual comparison.
    1. Neuroscience

    A genuine layer 4 in motor cortex with prototypical synaptic circuit connectivity

    Naoki Yamawaki, Katharine Borges ... Gordon M G Shepherd
    New evidence challenges the long-held view that motor cortex lacks a fourth layer, and reveals that its circuitry resembles that of other cortical regions more than previously thought.
    1. Neuroscience

    Causal manipulation of functional connectivity in a specific neural pathway during behaviour and at rest

    Vanessa M Johnen, Franz-Xaver Neubert ... Matthew F S Rushworth
    Functional connectivity in the human brain reflects changes in synaptic plasticity induced with repeated paired stimulation.
    1. Neuroscience

    Cellular resolution circuit mapping with temporal-focused excitation of soma-targeted channelrhodopsin

    Christopher A Baker, Yishai M Elyada ... M McLean Bolton
    Combining spatial restriction of channelrhodopsin to the neuronal cell body with two photon excitation and calcium imaging will enable production of high resolution maps of neural circuitry.
    1. Neuroscience

    Ephrin-B3 controls excitatory synapse density through cell-cell competition for EphBs

    Nathan T Henderson, Sylvain J Le Marchand ... Matthew B Dalva
    Competition between neurons for postsynaptic ephrin-B3 controls distribution of a limited pool of synapses and defines a novel trans-synaptic mechanism enabling neurons to set the number of synapses they receive.
    1. Neuroscience

    Mechanisms of distributed working memory in a large-scale network of macaque neocortex

    Jorge F Mejías, Xiao-Jing Wang
    An anatomically constrained computational model of the macaque cortical network demonstrates the emergence of large-scale distributed patterns of mnemonic activity sustained by long-range cortico-cortical interactions.
    1. Neuroscience

    Learning excitatory-inhibitory neuronal assemblies in recurrent networks

    Owen Mackwood, Laura B Naumann, Henning Sprekeler
    The synaptic structure in mouse V1 is explained by a synergy of homeostatic plasticity in incoming and outgoing synapses of inhibitory interneurons, establishing a stimulus-specific balance of excitation and inhibition.
    1. Neuroscience

    Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

    Noga Mosheiff, Yoram Burak
    The neural representation of position in the medial entorhinal cortex may be stabilized by synaptic connectivity across modules, which enforces coherent updates in their states.
    1. Neuroscience

    Learning accurate path integration in ring attractor models of the head direction system

    Pantelis Vafidis, David Owald ... Richard Kempter
    A theoretical model combines self-supervised predictive learning with structural inductive biases to reveal how quasi-continuous attractors that perform accurate angular path integration can be learned from experience during development in the Drosophila and potentially other animal models.
