    Repair of noise-induced damage to stereocilia F-actin cores is facilitated by XIRP2 and its novel mechanosensor domain

    Elizabeth L Wagner, Jun-Sub Im ... Jung-Bum Shin
    A novel mechanism for F-actin repair is involved in the maintenance of sensory hair cells and hearing function.

    Neural circuit-wide analysis of changes to gene expression during deafening-induced birdsong destabilization

    Bradley M Colquitt, Kelly Li ... Michael S Brainard
    Large-scale gene expression analysis of the songbird brain identifies the molecular and cellular features of vocal motor circuits that are altered by the loss of hearing.

    The dark kinase STK32A regulates hair cell planar polarity opposite of EMX2 in the developing mouse inner ear

    Shihai Jia, Evan M Ratzan ... Michael R Deans
    The planar polarized organization of vestibular hair cells in the mouse inner ear is determined by the coordinated activities of the STK32A kinase and the transcription factor EMX2 to regulate the orphan receptor GPR156.

    Large-scale electrophysiology and deep learning reveal distorted neural signal dynamics after hearing loss

    Shievanie Sabesan, Andreas Fragner ... Nicholas A Lesica
    Deep neural network modeling of auditory processing identifies distorted cross-frequency interactions as the key problem for the processing of speech in noise after hearing loss.

    Synaptic and circuit mechanisms prevent detrimentally precise correlation in the developing mammalian visual system

    Ruben A Tikidji-Hamburyan, Gubbi Govindaiah ... Matthew T Colonnese
    The imprecise and broad connectivity of retinal inputs during development have the potential to generate large correlations in target neurons that reduce retinotopic information unless suppressed by the special synaptic and circuit properties present at these ages.

    Experience-dependent flexibility in a molecularly diverse central-to-peripheral auditory feedback system

    Michelle M Frank, Austen A Sitko ... Lisa V Goodrich
    Single-nucleus sequencing, anatomy, and physiology reveal heterogeneity among olivocochlear neurons (a group of cells that provide feedback to the inner ear), identify a neuropeptide-enriched subtype, and show that neuropeptide expression changes during postnatal development and after sound exposure.

    Single-cell transcriptomic profiling of the zebrafish inner ear reveals molecularly distinct hair cell and supporting cell subtypes

    Tuo Shi, Marielle O Beaulieu ... David W Raible
    Single-cell transcriptomic analysis defines hair cell and supporting cell types in the zebrafish inner ear, and reveals homologies with cells in the mammalian ear.

    Cellular reprogramming with ATOH1, GFI1, and POU4F3 implicate epigenetic changes and cell-cell signaling as obstacles to hair cell regeneration in mature mammals

    Amrita A Iyer, Ishwar Hosamani ... Andrew K Groves
    Cells of the mammalian cochlea can be reprogrammed to produce mechanosensory hair cells, but epigenetic changes in the cochlea make this process less efficient with age.

    Presynaptic Rac1 controls synaptic strength through the regulation of synaptic vesicle priming

    Christian Keine, Mohammed Al-Yaari ... Samuel M Young Jr
    A combination of genetic, electrophysiological, and modeling approaches reveals that presynaptic Rac1 is a key molecule that controls synaptic strength and plasticity by regulating the synaptic vesicle cycle steps controlling the number of fusion competent synaptic vesicles.

    Repressor element 1-silencing transcription factor deficiency yields profound hearing loss through Kv7.4 channel upsurge in auditory neurons and hair cells

    Haiwei Zhang, Hongchen Li ... Ping Lv
    In the cochlea, repressor element 1-silencing transcription factor (REST) regulates the expression levels of Kv7.4 and alterations of REST functions result in progressive hearing loss.
