    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.

    Memory: Overwriting the past with supervised plasticity

    Xingyun Wang, Richard Naud
    Triggered activity bursts in place cells can increase and decrease the strength of some inputs.

    Global organization of neuronal activity only requires unstructured local connectivity

    David Dahmen, Moritz Layer ... Moritz Helias
    Short-ranged and random connectivity are sufficient to explain complex, long-range activity patterns observed in macaque motor cortex that are, moreover, flexibly adaptable to behavior.

    The landscape of regulatory genes in brain-wide neuronal phenotypes of a vertebrate brain

    Hui Zhang, Haifang Wang ... Jie He
    Single-cell transcriptomes of larval zebrafish whole brain shed light on the multidimensional landscapes of transcription factors and post-transcriptional regulators in vertebrate whole-brain neuronal classification and revealed principles of how neuronal cell diversity develops and evolves.

    Molecular structures and conformations of protocadherin-15 and its complexes on stereocilia elucidated by cryo-electron tomography

    Johannes Elferich, Sarah Clark ... Eric Gouaux
    Direct imaging of individual molecules of the tip-link protein PCDH15 in mouse stereocilia shows that it assembles as a dimer, forms complexes that span stereocilia, and occurs in clusters with multiple copies of the PCDH15 dimer.

    Connexins evolved after early chordates lost innexin diversity

    Georg Welzel, Stefan Schuster
    An in silico analysis of gap junction proteins supports the hypothesis that connexins replaced the primordial innexins in chordate gap junctions due to an evolutionary bottleneck.

    Open-source, Python-based, hardware and software for controlling behavioural neuroscience experiments

    Thomas Akam, Andy Lustig ... Mark E Walton
    pyControl is an open-source tool that makes it easy to specify complex behavioural tasks, run them at scale on low-cost hardware, and communicate task logic to other researchers.

    Similar neural and perceptual masking effects of low-power optogenetic stimulation in primate V1

    Spencer Chin-Yu Chen, Giacomo Benvenuti ... Eyal Seidemann
    Simultaneous optogenetic stimulation and calcium imaging in V1 of behaving macaques reveals that low-power optostimulation can substitute a visual mask and significantly reduce perceptual and neural detection sensitivities.

    Context-dependent relationships between locus coeruleus firing patterns and coordinated neural activity in the anterior cingulate cortex

    Siddhartha Joshi, Joshua I Gold
    Simultaneous recordings in brainstem and cortex, combined with pupillometry, show that changes in coordinated activity in anterior cingulate cortex are related to distinct patterns of pupil-linked activation of the locus coeruleus-norepinephrine system.

    A theory of synaptic transmission

    Bin Wang, Olga K Dudko
    The analytic theory establishes the general principles of synaptic transmission, enables extraction of microscopic parameters of synaptic fusion machinery from experiments, and links molecular constituents to synaptic function.
