    Dendritic coincidence detection in Purkinje neurons of awake mice

    Christopher J Roome, Bernd Kuhn
    Simultaneous voltage and calcium two-photon imaging of Purkinje neuron dendrites in awake mice reveals multiple interplaying mechanisms underlying sensory-evoked dendritic coincidence detection of parallel fiber and climbing fiber input.

    AMPA receptor mediated synaptic excitation drives state-dependent bursting in Purkinje neurons of zebrafish larvae

    Mohini Sengupta, Vatsala Thirumalai
    In vivo recordings in unanesthetized zebrafish larvae show that Purkinje neurons have two stable membrane potential states and that climbing fiber inputs can toggle them to up states during motor episodes.

    FGF14 modulates resurgent sodium current in mouse cerebellar Purkinje neurons

    Haidun Yan, Juan L Pablo ... Geoffrey S Pitt
    The N-terminus of the FGF14b isoform promotes the inactivation of voltage-gated Na+ channels to regulate the resurgent Na+ channel current needed for high frequency action potentials.

    Age-dependent dormant resident progenitors are stimulated by injury to regenerate Purkinje neurons

    N Sumru Bayin, Alexandre Wojcinski ... Alexandra L Joyner
    Injury at birth induces immature neurons to divide and regenerate cerebellar Purkinje cells in a time-dependent manner.

    Multiplexed coding by cerebellar Purkinje neurons

    Sungho Hong, Mario Negrello ... Erik De Schutter
    Cerebellar Purkinje neurons use a multiplexed simple spike code combining synchrony/spike time and firing rate, with each component encoding distinct information about movements such as motion onset timing and kinematics.

    Cerebellar nuclei excitatory neurons regulate developmental scaling of presynaptic Purkinje cell number and organ growth

    Ryan T Willett, N Sumru Bayin ... Alexandra L Joyner
    The first born excitatory cerebellar nuclei neurons influence the survival of their Purkinje cell partners which stimulate the expansion of granule cells and interneurons to produce functional local circuits.

    5-Hydroxymethylcytosine-mediated active demethylation is required for mammalian neuronal differentiation and function

    Elitsa Stoyanova, Michael Riad ... Nathaniel Heintz
    5-Hydroxymethylcytosine-mediated active DNA demethylation occurs in postmitotic neurons, and is required for their terminal differentiation and function.

    TTBK2 and primary cilia are essential for the connectivity and survival of cerebellar Purkinje neurons

    Emily Bowie, Sarah C Goetz
    Signaling at the primary cilium is important to sustain the morphology, connectivity, and survival of a key neural population within the brain.

    Gjd2b-mediated gap junctions promote glutamatergic synapse formation and dendritic elaboration in Purkinje neurons

    Sahana Sitaraman, Gnaneshwar Yadav ... Vatsala Thirumalai
    A protein that is a building block of intercellular bridges between neurons promotes their ability to grow dendrites and make synapses.
