    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.

    Synthesis of a comprehensive population code for contextual features in the awake sensory cortex

    Evan H Lyall, Daniel P Mossing ... Hillel Adesnik
    Novel stimulation patterns and large-scale neural activity recording show that an input-specific supra-linear summation synthesizes a sparse, but comprehensive code of tactile and visual stimuli in the sensory cortex.

    Precise and stable edge orientation signaling by human first-order tactile neurons

    Vaishnavi Sukumar, Roland S Johansson, J Andrew Pruszynski
    Individual human first-order tactile neurons, those that innervate the mechanoreceptors in the skin, can signal information about edge orientation differences at the limit of what people can feel and across a broad range of speeds relevant for real-world hand use.

    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.

    Neural coding in barrel cortex during whisker-guided locomotion

    Nicholas James Sofroniew, Yurii A Vlasov ... Karel Svoboda
    A tactile virtual reality system reveals the neural codes in the barrel cortex that underlie wall-tracking in mice.
    1. Neuroscience

    Stretching the skin immediately enhances perceived stiffness and gradually enhances the predictive control of grip force

    Mor Farajian, Raz Leib ... Ilana Nisky
    Elucidating the contribution of augmented artificial skin-stretch stimulation to the fingertips to the immediate illusion of a higher stiffness and to an increased predictive grip force control.

    Massive cortical reorganization in sighted Braille readers

    Katarzyna Siuda-Krzywicka, Łukasz Bola ... Marcin Szwed
    Teaching a tactile alphabet to sighted adults reveals the brain’s unexpected potential for change.
    1. Neuroscience

    External location of touch is constructed post-hoc based on limb choice

    Femke Maij, Christian Seegelke ... Tobias Heed
    Humans retrospectively localize touch after deciding on which limb it occurred, challenging the mainstream idea that tactile location in space is the basis for assigning touch to a body part.
    1. Neuroscience

    Active tactile discrimination is coupled with and modulated by the cardiac cycle

    Alejandro Galvez-Pol, Pavandeep Virdee ... James Kilner
    Human subjects actively adjust the acquisition of sense data based on how their bodily cycles alter their senses, i.e., sensing tactile stimuli for longer periods when concurrent physiological signals are present vs. sensing for shorter periods when these are quiescent.

    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.
