Postnatal maturation of auditory-nerve heterogeneity, as seen in spatial gradients of synapse morphology in the inner hair cell area [PDF]

Hearing Research, 2016
Auditory nerve fibers in the adult ear are divided into functional subgroups according to spontaneous rate (SR) and threshold sensitivity. The high-threshold, low-SR fibers are morphologically and spatially distinct from the low-threshold high-SR fibers at their synaptic contacts with inner hair cells.

Synaptic Dysfunction in the Anterior Cingulate Cortex Underlies Pain‐Anxiety Comorbidity in a Mandibular Asymmetry Mouse Model

Advanced Science, EarlyView.
This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...

Tsukushi is essential for the development of the inner ear

Molecular Brain, 2020
Tsukushi (TSK)—a small, secreted, leucine-rich-repeat proteoglycan—interacts with and regulates essential cellular signaling cascades. However, its functions in the mouse inner ear are unknown.

Treating Hearing Loss: From Cochlear Implantation to Gene Therapy

Advanced Science, EarlyView.
Cochlear implantation is the primary treatment for deafness, restoring functional hearing in over a million people. Recently, gene therapy has enabled biological hearing restoration in a small number of patients with OTOF‐related mutations. This perspective evaluates both approaches, concluding that cochlear implants will remain the standard for most ...

Speech Recognition with Cochlea‐Inspired In‐Sensor Computing

Advanced Intelligent Systems, EarlyView.
Traditional speech recognition methods rely on software‐based feature extraction that introduces latency and high energy costs, making them unsuitable for low‐power devices. A proof‐of‐concept demonstration is provided of a bioinspired tonotopic sensor for speech recognition that mimics the human cochlea, using a spiral‐shaped elastic metamaterial. The

A Novel Missense Variant in LMX1A Leads to Autosomal Dominant Nonsyndromic Hearing Loss

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Hereditary nonsyndromic hearing loss (NSHL) is a prevalent entity associated with over 150 known causative genes, including LMX1A, which has fewer than 10 reported pathogenic variants. Here we present a novel missense variant in LMX1A in a family of European descent with hereditary hearing loss. Clinical and family histories were obtained, and

Cutting‐Edge Advancements in Physical Stimulation for Spiral Ganglion Neuron Protection and Regeneration

Advanced NanoBiomed Research, EarlyView.
Physical stimulation strategies have emerged as a therapeutic avenue for the regeneration of spiral ganglion neurons. This review explores diverse physical stimulation modalities—including topographical modulation, electrical stimulation, and photostimulation—each operating through distinct mechanisms to regulate SGN biological behavior. By elucidating

Viral-mediated Ntf3 overexpression disrupts innervation and hearing in nondeafened guinea pig cochleae

Molecular Therapy: Methods & Clinical Development, 2016
Synaptopathy in the cochlea occurs when the connection between inner hair cells and the auditory nerve is disrupted, leading to impaired hearing and nerve degeneration. Experiments using transgenic mice have shown that overexpression of NT3 by supporting

Deletion of SLC19A2, the High Affinity Thiamine Transporter, Causes Selective Inner Hair Cell Loss and an Auditory Neuropathy Phenotype [PDF]

Journal of the Association for Research in Otolaryngology, 2006
Mutations in the gene coding for the high-affinity thiamine transporter Slc19a2 underlie the clinical syndrome known as thiamine-responsive megaloblastic anemia (TRMA) characterized by anemia, diabetes, and sensorineural hearing loss. To create a mouse model of this disease, a mutant line was created with targeted disruption of the gene.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...
