    Cell assemblies at multiple time scales with arbitrary lag constellations

    Eleonora Russo, Daniel Durstewitz
    A novel statistical algorithm for mining high-dimensional spike train (count) data for significant spatio-temporal patterns reveals new insights into task and brain area dependent functional organization of neural activity.

    Dipolar extracellular potentials generated by axonal projections

    Thomas McColgan et al.
    Action potentials propagating in axon bundles with bifurcating and terminating fibers cause strong and far-reaching extracellular potentials.

    A geometric attractor mechanism for self-organization of entorhinal grid modules

    Louis Kang, Vijay Balasubramanian
    The hierarchy of entorhinal grid cell modules with constant scale ratios can self-organize through a new geometrically organized attractor mechanism.

    How biological attention mechanisms improve task performance in a large-scale visual system model

    Grace W Lindsay, Kenneth D Miller
    Implementing neural changes associated with attention in a deep neural network causes performance changes that mimic those observed in humans and macaques.

    Learning multiple variable-speed sequences in striatum via cortical tutoring

    James M Murray, G Sean Escola
    Inspired by the sparse, sequential neural activity patterns observed in striatum, a new circuit model implements variable-speed activity, the encoding of multiple sequences, and a tutor/student relationship between cortex and striatum.

    A theory of joint attractor dynamics in the hippocampus and the entorhinal cortex accounts for artificial remapping and grid cell field-to-field variability

    Haggai Agmon, Yoram Burak
    A theory of coordinated neural network dynamics in multiple brain areas offers an explanation for several recent experimental findings in the hippocampus and medial entorhinal cortex.

    Science Forum: The Human Cell Atlas

    Aviv Regev et al.
    Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.

    Tuning movement for sensing in an uncertain world

    Chen Chen et al.
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    The head direction circuit of two insect species

    Ioannis Pisokas et al.
    Two evolutionary distant insect species share a common head direction circuit with subtle differences in neuronal morphologies that result in distinct circuit dynamics adapted to each species’ ecology.
