    The role of conjunctive representations in prioritizing and selecting planned actions

    Atsushi Kikumoto, Ulrich Mayr, David Badre
    Time-resolved decoding of EEG reveals the nature of representations of upcoming actions and how the planned action is selected from working memory.
    1. Neuroscience

    Successor-like representation guides the prediction of future events in human visual cortex and hippocampus

    Matthias Ekman, Sarah Kusch, Floris P de Lange
    Early visual cortex (V1) and hippocampal cortex represent a predictive map of the visual world akin to the successor representation.
    1. Neuroscience

    Neural learning rules for generating flexible predictions and computing the successor representation

    Ching Fang, Dmitriy Aronov ... Emily L Mackevicius
    A recurrent network using a simple, biologically plausible learning rule can learn the successor representation, suggesting that long-horizon predictions are computations that are easily accessible in neural circuits.
    1. Neuroscience

    Consolidation alters motor sequence-specific distributed representations

    Basile Pinsard, Arnaud Boutin ... Julien Doyon
    The consolidation of newly acquired motor skills induces a functional reorganization of sequential information representations within secondary motor cortex, basal ganglia and hippocampus.
    1. Neuroscience

    The representational space of observed actions

    Raffaele Tucciarelli, Moritz Wurm ... Angelika Lingnau
    Representational similarity analysis of human functional magnetic resonance imaging data demonstrates that the lateral occipitotemporal cortex represents action knowledge along dimensions that are in accordance with behavioural judgements.
    1. Neuroscience

    Neural representation of newly instructed rule identities during early implementation trials

    Hannes Ruge, Theo AJ Schäfer ... Uta Wolfensteller
    Ventro-lateral prefrontal cortex codes novel rules starting from their first-time implementation right after instruction while early consolidation is channeled through increasing cooperation with the anterior striatum.
    1. Neuroscience

    Early language exposure affects neural mechanisms of semantic representations

    Xiaosha Wang, Bijun Wang, Yanchao Bi
    Impoverished access to natural human language during early childhood reduces semantic structure encoding in the left dorsal anterior temporal lobe, which provides positive evidence for the role of language in forming specific neural semantic representations in the human brain.
    1. Neuroscience

    Coordinated head direction representations in mouse anterodorsal thalamic nucleus and retrosplenial cortex

    Marie-Sophie H van der Goes, Jakob Voigts ... Mark T Harnett
    Dual site recordings of mouse anterodorsal thalamic nucleus and retrosplenial cortex reveal near 0-ms lag between the head direction representations of the two regions after cue rotations and correlated drift in darkness.
    1. Neuroscience

    THINGS-data, a multimodal collection of large-scale datasets for investigating object representations in human brain and behavior

    Martin N Hebart, Oliver Contier ... Chris I Baker
    THINGS-data reflects three large-scale neuroimaging and behavioral datasets of object processing in humans, comprising densely sampled functional MRI and magnetoencephalographic recordings, as well as 4.70 million similarity judgments in response to thousands of photographic images for up to 1854 objects.
    1. Neuroscience

    Increasing stimulus similarity drives nonmonotonic representational change in hippocampus

    Jeffrey Wammes, Kenneth A Norman, Nicholas Turk-Browne
    Hippocampal learning in dentate gyrus follows a U-shaped function, with moderate, but not high or low, overlap between representations leading to differentiation of neural patterns.
