    Dye-enhanced visualization of rat whiskers for behavioral studies

    Jacopo Rigosa, Alessandro Lucantonio ... Mathew E Diamond
    A simple fluorescent dye method allows visualization of whiskers, facilitating studies of rodent tactile behavior.
    1. Neuroscience

    Potentiation of cerebellar Purkinje cells facilitates whisker reflex adaptation through increased simple spike activity

    Vincenzo Romano, Licia De Propris ... Chris I De Zeeuw
    Physiological and behavioral analyses show that expression of cerebellar whisker learning can be mediated by increased simple spike activity, depending on LTP induction at parallel fiber to Purkinje cell synapses.
    1. Neuroscience

    Tapered whiskers are required for active tactile sensation

    Samuel Andrew Hires, Lorenz Pammer ... David Golomb
    The tapered, conical shape of rodent whiskers is essential for sensor mobility in constrained spaces and feature extraction from textured surfaces.
    1. Neuroscience

    Peripheral optogenetic stimulation induces whisker movement and sensory perception in head-fixed mice

    Sunmee Park, Akhil Bandi ... David J Margolis
    Light can be used to trigger the contraction of facial muscles and movement of the whiskers in transgenic mice, aiding the study of active sensation.
    1. Neuroscience

    Enrichment drives emergence of functional columns and improves sensory coding in the whisker map in L2/3 of mouse S1

    Amy M LeMessurier, Keven J Laboy-Juárez ... Daniel E Feldman
    Sensory enrichment creates a more columnar, less salt-and-pepper whisker map in somatosensory cortex, showing that impoverished experience contributes to intermixed tuning in rodent sensory maps.
    1. Neuroscience

    Coding of whisker motion across the mouse face

    Kyle S Severson, Duo Xu ... Daniel H O'Connor
    Electrophysiology and information theory show that diverse classes of mechanoreceptors in the face inform the mouse brain about whisking.
    1. Neuroscience

    A rapid whisker-based decision underlying skilled locomotion in mice

    Richard A Warren, Qianyun Zhang ... Nathaniel B Sawtell
    A rapid whisker-based decision underlies skilled locomotion in mice largely independent of cerebral cortex.
    1. Neuroscience

    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.

    Decoupling kinematics and mechanics reveals coding properties of trigeminal ganglion neurons in the rat vibrissal system

    Nicholas E Bush, Christopher L Schroeder ... Mitra JZ Hartmann
    Primary sensory neurons of the rat whisker system encode contact with objects in terms of the forces exerted on whiskers, rather than the induced whisker movements.
    1. Neuroscience

    The cerebellum linearly encodes whisker position during voluntary movement

    Susu Chen, George J Augustine, Paul Chadderton
    Cerebellar Purkinje cells represent movements via bidirectional linear changes in spike rate, and activity from single cells is sufficient to reconstruct kinematic changes during bouts of free whisking.
