- The National Institute on Deafness and Other Communication Disorders awarded the University of Texas at Austin $382,867 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds research on dendritic integration and synaptic plasticity in the medial superior olive (MSO), the first critical stage for processing interaural time differences—temporal cues the brain uses for horizontal sound localization and speech perception in...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Texas at Austin $439,875 on July 10, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop an in vivo cell labeling system in Mongolian gerbils linking sensory perception to underlying brain circuitry in sound localization. The research focuses on the superior olivary complex, specifically the medial and lateral superior olive nuclei that process...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Texas at Austin $192,953 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate the role of extended high frequencies on speech perception challenges in aging. The research addresses a critical gap in clinical audiology: many adults experience difficulty understanding speech in noisy environments by midlife despite normal results on...
- The National Institute on Deafness and Other Communication Disorders awarded the University of South Florida $164,329 on September 16, 2025, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to conduct parallel human and animal studies examining associations between extended high frequency hearing loss, speech-in-noise performance, and cognitive decline in aging populations. The funded research encompasses two coordinated aims. Aim 1 involves assessment...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Pittsburgh $664,448 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds investigation of how heterogeneous neural responses in auditory cortex and secondary motor cortex contribute to auditory learning and perception. The project combines large-scale neural recordings with optogenetic manipulations to examine how local auditory...
- The National Institute on Deafness and Other Communication Disorders awarded Massachusetts Eye and Ear Infirmary $467,323 on July 10, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate auditory-arousal circuits in normal and disordered hearing. The project characterizes central auditory function across all brain states, including sleep, and relates arousal dysregulation to the degree of auditory perceptual gain in subjects with hearing...
- 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, a component of the National Institutes of Health under the Department of Health and Human Services, awarded $350,000 to The Medical University of South Carolina on July 10, 2026, under the Biomedical Research and Research Training program (CFDA 93.859) to investigate neural plasticity mechanisms in aging adults with hearing loss. The research targets two aspects of brain adaptation to age-related hearing loss:...
- The National Institute on Deafness and Other Communication Disorders awarded $244,740 to the University of California, San Diego on September 30, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) for a multidimensional analysis of cochlear pathology in sensorineural hearing loss. The project leverages artificial intelligence to automate high-resolution quantification of hair cell synapses and stereocilia in fixed cochlear tissues and establish...
- The National Institute on Deafness and Other Communication Disorders awarded Rutgers The State University of New Jersey $542,818 under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) on August 1, 2026. The award funds investigation of how noise-induced hearing loss impairs auditory decision-making by disrupting neural pathways between auditory cortex and parietal cortex. The research tests whether noise-induced hearing loss impairs the ascending projections...
The National Institute on Deafness and Other Communication Disorders awarded The University of Texas at San Antonio $466,462 on July 28, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate mechanisms of serotonergic signaling in the auditory midbrain in aging. The research examines how serotonin regulates the balance of excitatory and inhibitory circuits in the inferior colliculus, a region of the auditory midbrain, and how this regulation changes in age-related hearing loss. The project will determine how serotonergic receptor expression and serotonergic synapses to distinct classes of neurons in the inferior colliculus change in young mice with normal hearing versus older mice with age-related hearing loss, and will measure how exogenously and endogenously released serotonin alters the activity of inhibitory GABAergic and excitatory glutamatergic neurons. The research targets serotonergic modulation as a potential intervention point because serotonin can influence neural excitability without directly disrupting basic neural functions. The award funds work performed at San Antonio, Texas. The period of performance extends from July 28, 2026, to June 30, 2031. This is a Project Grant, the primary assistance type under NIDCD's Research Related to Deafness and Communication Disorders program.
