    Sampling motion trajectories during hippocampal theta sequences

    Balazs B Ujfalussy, Gergő Orbán
    The rodent brain represents uncertainty associated with short-term predictions during naturalistic navigation tasks sequentially by sampling hypothetical future trajectories in every ~100 ms, corresponding to successive theta cycles.

    Neural structure mapping in human probabilistic reward learning

    Fabrice Luyckx, Hamed Nili ... Christopher Summerfield
    During learning, human neural codes for experienced reward probability map onto the same mental number line for symbolic numbers.

    Control of entropy in neural models of environmental state

    Timothy H Muller, Rogier B Mars ... Jill X O'Reilly
    Evidence for neuromodulatory control of flexibility in human neural models.

    Integrated externally and internally generated task predictions jointly guide cognitive control in prefrontal cortex

    Jiefeng Jiang, Anthony D Wagner, Tobias Egner
    The dorsolateral prefrontal cortex integrates concurrent externally and internally generated predictions of task demand to guide information processing, while the medial prefrontal cortex corrects its prediction error based on actual task demand.

    A principle of economy predicts the functional architecture of grid cells

    Xue-Xin Wei, Jason Prentice, Vijay Balasubramanian
    Mathematical modeling suggests that grid cells in the rodent brain use fundamental principles of number theory to maximize the efficiency of spatial mapping, enabling animals to accurately encode their location with as few neurons as possible.

    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.

    Finding structure during incremental speech comprehension

    Bingjiang Lyu, William D Marslen-Wilson ... Lorraine K Tyler
    Structural representations of sentences generated by deep language models correlate with human listeners' behaviours and neural activity, providing a quantifiable framework to uncover the neural dynamics underpinning incremental speech comprehension.

    Uncertainty leads to persistent effects on reach representations in dorsal premotor cortex

    Brian M Dekleva, Pavan Ramkumar ... Lee E Miller
    When Rhesus monkeys plan reaching movements of which they are not fully confident, a particular area of the brain represents both the chosen action as well as alternate movements, perhaps as an aid for error correction or learning.

    Obtaining and maintaining cortical hand representation as evidenced from acquired and congenital handlessness

    Daan B Wesselink, Fiona MZ van den Heiligenberg ... Tamar R Makin
    fMRI results show that despite arm amputation, and varying degrees of phantom sensations, canonical hand representation in primary somatosensory cortex is largely maintained.

    Integrating prediction errors at two time scales permits rapid recalibration of speech sound categories

    Itsaso Olasagasti, Anne-Lise Giraud
    Keeping flexible adaptable representations of speech categories at different time scales allows the brain to maintain stable perception in the face of varying speech sound characteristics.
