    Visually-updated hand state estimates modulate the proprioceptive reflex independently of motor task requirements

    Sho Ito, Hiroaki Gomi
    Distortion and elimination of limb visual feedback affects low-level stretch reflex control, indicating the involvement of a high-level and multimodal representation of the limb state in orchestrating hierarchical sensorimotor control.

    Functional gradients of the cerebellum

    Xavier Guell, Jeremy D Schmahmann ... Satrajit S Ghosh
    Cerebellar functional regions follow a gradual organization, which progresses from primary (motor) to transmodal (Default Mode Network) regions, and a secondary axis extends from task-unfocused to task-focused processing.

    Unimodal statistical learning produces multimodal object-like representations

    Gábor Lengyel, Goda Žalalytė ... Daniel M Wolpert
    Mere exposure to scenes with statistical contingencies in the visual or haptic modality alone allows participants to decompose scenes into object-like multimodal representations.

    A double dissociation between semantic and spatial cognition in visual to default network pathways

    Tirso RJ Gonzalez Alam, Katya Krieger-Redwood ... Elizabeth Jefferies
    Default mode network and visual cortex are connected via two parallel pathways that differentially respond to the processing of visual scenes and semantic information about objects, reflecting domain-specific organisation.

    Learning precise spatiotemporal sequences via biophysically realistic learning rules in a modular, spiking network

    Ian Cone, Harel Z Shouval
    A computational model shows that it's possible to learn and replay extended temporal sequences in a network of spiking neurons with a modular architecture and a biologically realistic learning rule.

    Disynaptic cerebrocerebellar pathways originating from multiple functionally distinct cortical areas

    Julia U Henschke, Janelle MP Pakan
    Anatomical projections from sensory, motor, and association cortex to the cerebellum are precisely mapped, including cortical-precerebellar connections and terminal organization, providing insight into how the cerebellum may utilize cortical information.

    Stability of motor representations after paralysis

    Charles Guan, Tyson Aflalo ... Richard A Andersen
    Neural populations in PPC dynamically represent motor-like and then sensory-like aspects of brain–computer interface finger movements with a representational structure that matches able-bodied individuals.

    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.

    Encoding and control of orientation to airflow by a set of Drosophila fan-shaped body neurons

    Timothy A Currier, Andrew MM Matheson, Katherine I Nagel
    Electrophysiology identifies a population of fan-shaped body neurons that encode airflow in two directions relative to the fly midline and whose silencing disrupts proper orientation to airflow.

    Task-dependent optimal representations for cerebellar learning

    Marjorie Xie, Samuel P Muscinelli ... Ashok Litwin-Kumar
    Classical theoretical approaches to studying the cerebellar cortex are generalized to a broader set of learning tasks, revealing that the optimal value for the sparsity of granule cell activity is task-dependent.
