    Here we show how PFL2 and PFL3 neurons in the Drosophila brain compare a representation of direction with internal spatial goals, both anchored in world-centric coordinates, and produce body-centric steering commands that act to correct deviations from the goal direction.

    Neural population activity in the medial entorhinal cortex of mice can be organized into ultraslow oscillatory sequences, with periods extending up to the minute range.

    Mapping of the mouse cerebellar cortex using 3D reconstruction from electron microscopy, as well as numerical simulation of neuronal activity, shows non-random redundancy of connectivity that may favour resilient learning over encoding capacity.

    A study presents ensemble recordings of neurons in the lumbar spinal cord indicating that activity in spinal cord circuits for movement follows low-dimensional rotational dynamics, and proposes a theory of neural generation of movements.

    Predictive models that relate brain activity to phenotype reliably fail when applied to subgroups of participants who do not fit stereotypical profiles, showing that the utility of a one-size-fits-all modelling approach is limited.

    The mouse neocortex supports sensory performance through transient increases in sensory coding redundancy, neural codes that are robust to cellular variability, and inter-area fluctuation modes that transmit sensory data and task responses in non-interfering channels.

    Simultaneous recordings from hundreds of grid cells in rats, combined with topological data analysis, show that network activity in grid cells resides on a toroidal manifold that is invariant across environments and brain states.

    Single-cell tracing and optogenetics manipulation in mice are used to show how spatial tuning of individual pyramidal cells in CA1 can propagate to and be amplified by their local subnetwork of neurons.

    Both piriform cortex and its sensory inputs from the olfactory bulb represent chemical odour relationships, but cortex reshapes relational information inherited from the sensory periphery to enhance odour generalization and to reflect experience.

    A microscopy system that enables simultaneous recording from hundreds of neurons in the mouse visual cortex reveals that the brain enhances its coding capacity by representing visual inputs in dimensions perpendicular to correlated noise.

    Quantitative connectivity matrices (or connectomes) for both adult sexes of the nematode Caenorhabditis elegans are presented that encompass all connections from sensory input to end-organ output across the entire animal.

    In mouse cortex, ‘preparatory’ activity that encodes future movements is remarkably robust against large-scale perturbations; this robustness is achieved by corrective signals from unperturbed parts of the network.

    Neural sequences recorded from the vocal premotor area HVC in juvenile birds learning song ‘syllables’ show ‘prototype’ syllables forming early, with multiple new highly divergent neural sequences emerging from this precursor syllable as learning progresses.

    On the basis of neural firing rates a specific class of neuron is identified in the medial entorhinal cortex that linearly encodes information on running speed in a context-independent manner and that is distinct from other functionally specific entorhinal neurons.

    Grid cells are cells of the brain’s internal map of space that fire when an animal is in a location corresponding to the vertices of a hexagonal grid pattern tiling the entire environment; how the pattern is mapped onto the external environment has remained a mystery, however, new studies in rat reveal that the axes of the grid are determined by the boundaries of the external environment and provide insight into the rotation of the grid axis in relation to these boundaries.

    Grid cells confer a spatial impression of an animal's environment on the brain. Their firing patterns in a cave-dwelling bat reopen old questions about how they do this, and pose some compelling new ones. See Letter p.103

    The idea that artificial neural networks could be based on molecular components is not new, but making such a system has been difficult. A network of four artificial neurons made from DNA has now been created. See Letter p.368

    Ramón y Cajal, the founding father of neuroscience, observed similarities between the vertebrate retina and the insect eye, but that was based purely on anatomy. Using state-of-the-art genetics and electrophysiology in the fruitfly, these authors distinguish motion-sensitive neurons responding to abrupt increases in light from those specific to light decrements, thus bringing the similarity with vertebrate circuitry to the functional level.

    Modern networks are rarely independent, instead being coupled together with many others. Thus the failure of a small fraction of nodes in one network may lead to the complete fragmentation of a system of several interdependent networks. Here, a framework is developed for understanding the robustness of interacting networks subject to such 'cascading' failures. Surprisingly, a broader degree distribution increases the vulnerability of interdependent networks to random failure.
