- 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 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...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Texas at Dallas $416,155 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate neural mechanisms supporting naturalistic dyadic interactions in young adults with developmental language disorder (DLD) using high-density diffuse optical tomography. The research examines interindividual neural synchronization in language networks...
- The National Institute on Deafness and Other Communication Disorders awarded New York University $134,109 on December 19, 2025, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The funded research investigates plasticity and social neuromodulation of developing auditory cortical circuits in postnatal mice. The K99 phase employs longitudinal tracking of auditory cortex neurons from the onset of hearing throughout development to examine how external...
- 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 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...
- The National Institute on Deafness and Other Communication Disorders awarded the University of North Texas Research and Innovation Division $535,758 on May 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop a dynamic hypothermia protocol for hearing loss prevention. The recipient will conduct computational modeling, experimental validation, and device development to design a non-invasive cooling strategy targeting noise-induced hearing...
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 challenging listening environments. The research investigates how neurons in the MSO circuit acquire appropriate synaptic weights and firing properties during development, with particular focus on how auditory experience and early-life hearing loss impact binaural processing. The study uses the Mongolian gerbil as the model organism, selected for its low-frequency hearing comparable to humans and prominent MSO circuitry, and combines plasticity induction paradigms with novel electrophysiological and imaging approaches to test the hypothesis that morphological, synaptic, and intrinsic plasticity are tightly coordinated to adjust cell excitability and interaural time difference computations in normal development and following hearing loss. Performance occurs at the University of Texas at Austin in Austin, Texas through July 31, 2031. The University of Texas System is the parent institution.
