    Somatosensory neurons integrate the geometry of skin deformation and mechanotransduction channels to shape touch sensing

    Alessandro Sanzeni et al.
    Nonlinear elasticity of skin tissues and somatosensory neural responses are combined to predict and test C. elegans processing of touch stimuli and modifications due to changes in the body mechanics.

    Mapping quantal touch using 7 Tesla functional magnetic resonance imaging and single-unit intraneural microstimulation

    Rosa Maria Sanchez Panchuelo et al.
    The combination of intraneural microstimulation and 7T fMRI makes it possible to bridge the gap between first-order mechanoreceptive afferent input codes and their spatial, dynamic and perceptual representations in human cortex.

    Low-noise encoding of active touch by layer 4 in the somatosensory cortex

    Samuel Andrew Hires et al.
    Touch information is represented with minimal noise in the somatosensory cortex during tactile exploration.
    1. Neuroscience

    Computation identifies structural features that govern neuronal firing properties in slowly adapting touch receptors

    Daine R Lesniak et al.
    Computer simulations show that the firing patterns of branched touch receptors can be set in part by the organization of their sensory endings in the skin.

    Keratinocytes mediate innocuous and noxious touch via ATP-P2X4 signaling

    Francie Moehring et al.
    Keratinocytes are critical for normal innocuous and noxious touch through their mechanically evoked ATP release and subsequent signaling to P2X4 channels on sensory neurons.
    1. Neuroscience

    Acetylated tubulin is essential for touch sensation in mice

    Shane J Morley et al.
    Increased stiffness of sensory neurons in the absence of microtubule acetylation renders mice profoundly insensitive to touch and pain.

    Intracortical Microstimulation: Regaining the senses of touch and movement

    Victor de Lafuente
    Artificially activating certain neurons in the cortex can make a tetraplegic patient feel naturalistic sensations of skin pressure and arm movement.

    The cellular basis of mechanosensory Merkel-cell innervation during development

    Blair A Jenkins et al.
    Touch-sensitive neurons are patterned during mammalian skin development by placode-derived keratinocytes and Bone Morphogenetic Protein signaling.

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

    Calogero Maria Oddo et al.
    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.

    Fast and accurate edge orientation processing during object manipulation

    J Andrew Pruszynski et al.
    Tactile edge orientation processing during object manipulation is many times better than previously thought based on perceptual studies.
