    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.

    Uncertainty-based inference of a common cause for body ownership

    Marie Chancel, H Henrik Ehrsson, Wei Ji Ma
    Behavioral and computational results show that the perception of our body as our own depends on Bayesian probabilistic reasoning that take into account the variations in sensory uncertainty when integrating visual and somatosensory cues.

    Homoplasy in the evolution of modern human-like joint proportions in Australopithecus afarensis

    Anjali M Prabhat, Catherine K Miller ... Jeremy M DeSilva
    The human-like joint proportions of Australopithecus afarensis evolved independently, making 'Lucy' and her kind the earliest known evolutionary experiment in obligate bipedalism.

    Understanding implicit sensorimotor adaptation as a process of proprioceptive re-alignment

    Jonathan S Tsay, Hyosub Kim ... Richard B Ivry
    A new computational model reveals how implicit sensorimotor adaptation is elicited to re-align one's felt and desired hand position.

    Extrinsic and intrinsic dynamics in movement intermittency

    Damar Susilaradeya, Wei Xu ... Andrew Jackson
    The rhythmicity in upper-limb tracking movements and associated population dynamics in primary motor cortex is explained by a feedback controller incorporating optimal state estimation.

    The manifold structure of limb coordination in walking Drosophila

    Brian D DeAngelis, Jacob A Zavatone-Veth, Damon A Clark
    During walking and turning, the fruit fly Drosophila uses variable limb coordination patterns, which exist on a low-dimensional, continuous manifold.

    Action history influences subsequent movement via two distinct processes

    Welber Marinovic, Eugene Poh ... Timothy J Carroll
    Movement biases due to recent action history involve both dynamically-evolving processes reflecting prediction of future actions, and temporally-stable processes induced by movement repetition.

    Slowly evolving dopaminergic activity modulates the moment-to-moment probability of reward-related self-timed movements

    Allison E Hamilos, Giulia Spedicato ... John A Assad
    Dynamic dopaminergic signaling modulates the timing of reward-related movements by tuning the moment-to-moment probability of their onset.

    Influence of sensory modality and control dynamics on human path integration

    Akis Stavropoulos, Kaushik J Lakshminarasimhan ... Dora E Angelaki
    Human path integration accuracy is strongly influenced by the underlying control dynamics, but less so when visual, rather than vestibular, feedback is available.

    The role of V3 neurons in speed-dependent interlimb coordination during locomotion in mice

    Han Zhang, Natalia A Shevtsova ... Ilya A Rybak
    The role of genetically identified V3 interneurons with ascending propriospinal projections in the spinal locomotor circuitry and their contribution to the limb coordination and speed-dependent gait expression during locomotion were investigated using a combination of experimental studies and computational modeling.
