    Towards biologically plausible phosphene simulation for the differentiable optimization of visual cortical prostheses

    Maureen van der Grinten, Jaap de Ruyter van Steveninck ... Yağmur Güçlütürk
    The provided framework based on biological models and clinical literature can aid in the optimization of visual cortical prostheses through computational or behavioral simulation experiments, serving as a flexible tool for computational, clinical, and behavioral neuroscientists working on visual neuroprosthetics.

    Intuitive movement-based prosthesis control enables arm amputees to reach naturally in virtual reality

    Effie Segas, Sébastien Mick ... Aymar de Rugy
    A novel trans-humeral prosthesis control method based on artificial intelligence, and the proof of its effectiveness in virtual reality as well as on a robotic platform.
    1. Neuroscience

    Optogenetic activation of visual thalamus generates artificial visual percepts

    Jing Wang, Hamid Azimi ... Gregor Rainer
    The visual thalamus is a promising target for neural prosthetic intervention aimed at the restoration of visual function.
    1. Neuroscience

    Intraneural stimulation elicits discrimination of textural features by artificial fingertip in intact and amputee humans

    Calogero Maria Oddo, Stanisa Raspopovic ... Silvestro Micera
    Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.
    1. Neuroscience

    Sensory restoration by epidural stimulation of the lateral spinal cord in upper-limb amputees

    Santosh Chandrasekaran, Ameya C Nanivadekar ... Lee E Fisher
    Cervical spinal cord stimulation evokes sensory percepts in the missing hand and arm of people with upper-limb amputation, regardless of amputation level or time post-amputation.
    1. Neuroscience

    Augmented reality powers a cognitive assistant for the blind

    Yang Liu, Noelle RB Stiles, Markus Meister
    A non-invasive cognitive assistant for blind people endows objects in the environment with voices, allowing users to explore the scene, localize objects, and navigate through a building with minimal training.
    1. Neuroscience

    Probing the functional impact of sub-retinal prosthesis

    Sébastien Roux, Frédéric Matonti ... Frédéric Chavane
    Existing artificial retinas produce distorted and imprecise activation of the visual system, but reverse engineering promises to refine the induced activation patterns.
    1. Neuroscience

    Proof of concept for multiple nerve transfers to a single target muscle

    Matthias Luft, Johanna Klepetko ... Konstantin Davide Bergmeister
    A murine model for a novel surgical concept demonstrates potential advances of neuroprosthetic interfacing.
    1. Neuroscience

    Deprivation-related and use-dependent plasticity go hand in hand

    Tamar R Makin, Alona O Cramer ... Heidi Johansen-Berg
    In individuals with a missing hand, the area of the brain that would otherwise control that hand is recruited by either the remaining hand or the residual limb, depending on the usage preference of the individual.
    1. Neuroscience

    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.
