- The National Institute on Deafness and Other Communication Disorders awarded The Johns Hopkins University $194,270 on May 11, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate the development of auditory thalamocortical circuits and how they are altered in cases of congenital deafness. The project will establish a foundational understanding of how the thalamus and auditory cortex develop and mature through sensory experience, with...
- The National Institute on Deafness and Other Communication Disorders awarded The Johns Hopkins University $654,879 on July 17, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate cortical representations of electrical stimulation in cochlear implant recipients. The research elucidates fundamental neural coding and plasticity mechanisms responsible for cortical processing of cochlear implant signals. The project employs optical imaging and...
- The National Institute on Deafness and Other Communication Disorders awarded Northeast Ohio Medical University $132,486 on August 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds investigation of inhibitory nuclei within the trapezoid body and their roles in sound localization, addressing deficits in spatial hearing that commonly accompany age-related hearing loss and neurodevelopmental disorders. The project integrates...
- The National Institute on Deafness and Other Communication Disorders awarded The Johns Hopkins University $650,639 under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) on February 1, 2026. The award funds investigation of crossmodal plasticity in adult corticothalamic circuits, focusing on how visual deprivation triggers compensatory auditory system enhancement in mice. The research tests the hypothesis that widespread plasticity of the auditory pathway...
- The National Institute on Deafness and Other Communication Disorders awarded Oregon Health & Science University $645,488 on July 27, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to characterize how the auditory cortex processes speech and natural sounds in noisy, dynamic acoustic environments. The research addresses the clinical problem that listeners with hearing loss struggle to understand speech in complex noise despite hearing aids and...
- The National Institute on Deafness and Other Communication Disorders awarded The University of Chicago $451,000 on August 24, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop a native biochemical preparation of the mechanotransduction complex (METC) from cnidarian nematocytes as a model of vertebrate hair-cell function. The award funds research into the structural dynamics and functional mechanisms of the METC, the cellular machinery...
The National Institute on Deafness and Other Communication Disorders awarded Baylor College of Medicine $684,114 on August 21, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate how the dorsal cochlear nucleus, the brainstem circuit responsible for localizing sounds in the vertical plane, integrates multimodal sensory inputs—including ear movement, head movement, and neuromodulatory signals reflecting brain state—during active behavior to refine spatial sound localization. The project leverages transcriptional profiling and transgenic mouse lines targeting dorsal cochlear nucleus cell types, combined with a head-fixed mouse preparation that uses neuropixel recording of dorsal cochlear nucleus neurons, real-time ear movement tracking, and pupillometry to monitor brain state while animals localize sounds. The research will dissect how coordinated changes in ear position, ear movement, and brain state modulate neural activity in cell-type-specific patterns, with direct applications to improving cochlear implant and hearing aid performance in natural listening conditions and clarifying the neural bases of auditory pathologies such as tinnitus and hyperacusis. Performance occurs in Houston, Texas. The award runs through July 31, 2031. The assistance type is a Project Grant.
