    Fast and accurate edge orientation processing during object manipulation

    J Andrew Pruszynski, J Randall Flanagan, Roland S Johansson
    Tactile edge orientation processing during object manipulation is many times better than previously thought based on perceptual studies.
    1. Neuroscience

    Motor memories of object dynamics are categorically organized

    Evan Cesanek, Zhaoran Zhang ... J Randall Flanagan
    The motor-relevant properties of the myriad objects with which we interact on a daily basis are encoded in memory using categorical representations, or 'object families'.

    Natural forgetting reversibly modulates engram expression

    James D O'Leary, Rasmus Bruckner ... Tomás J Ryan
    Causal investigation of engram ensembles shows that natural forgetting is an active and reversible process driven by perceptual feedback, supporting the perspective of forgetting an adaptive function of the brain.
    1. Neuroscience

    Unsupervised changes in core object recognition behavior are predicted by neural plasticity in inferior temporal cortex

    Xiaoxuan Jia, Ha Hong, James J DiCarlo
    Temporal continuity-induced plasticity in individual neurons of inferior temporal cortex builds neural representations that underlie robust core object recognition behavior.
    1. Neuroscience

    Progressively shifting patterns of co-modulation among premotor cortex neurons carry dynamically similar signals during action execution and observation

    Zhonghao Zhao, Marc H Schieber
    Population trajectories of premotor cortex mirror neurons progress through distinct subspaces during execution versus observation of reach-grasp-manipulate movements, yet latent dynamics can be aligned, indicating similar relationships among neural representations.

    Entorhinal-retrosplenial circuits for allocentric-egocentric transformation of boundary coding

    Joeri BG van Wijngaarden, Susanne S Babl, Hiroshi T Ito
    An extended border coding circuit across the entorhinal and retrosplenial cortex incorporates self-referenced and viewpoint-invariant boundary information to guide navigation behavior.

    Columnar neurons support saccadic bar tracking in Drosophila

    Giovanni Frighetto, Mark A Frye
    Flies have two parallel visual pathways with specialized physiological properties to compensate for perturbations in their flight course and to saccade toward objects.

    Causal neural mechanisms of context-based object recognition

    Miles Wischnewski, Marius V Peelen
    Context-based object recognition causally relies on both scene- and object-selective cortex, with scene-selective cortex generating expectations (at 160-200 ms after onset) that disambiguate object representations in object-selective cortex (at 260-300 ms after onset).
    1. Neuroscience

    The large-scale organization of shape processing in the ventral and dorsal pathways

    Erez Freud, Jody C Culham ... Marlene Behrmann
    Functional neuroimaging reveals sensitivity to shape information and correlation between brain activation and perceptual behaviour in both dorsal and ventral visual pathways, thereby challenging the strict binary distinctions between the two pathways.
    1. Neuroscience

    Broca's cerebral asymmetry reflects gestural communication's lateralisation in monkeys (Papio anubis)

    Yannick Becker, Nicolas Claidière ... Adrien Meguerditchian
    A brain MRI imaging study on brain and manual lateralisation in 50 baboons shows that communicative manual gesturing is related to a Broca's area marker.
