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 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 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 New York University $381,376 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds experimental and computational investigation of synaptic plasticity rules engaged in auditory cortex development and learning. The research generates datasets on fundamental plasticity processes during critical developmental periods, comparing spike-timing-dependent...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Pittsburgh $659,250 on May 7, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds research into critical proteins regulating mechanotransduction channel trafficking and localization in cochlear hair cells, which are essential for converting sound waves into electrical signals and maintaining auditory function. The research addresses how...
The National Institute on Deafness and Other Communication Disorders awarded Carnegie Mellon University $100,228 on January 16, 2027, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop and apply a high-density cortical inactivation platform for studying distributed cortical feedback mechanisms in auditory processing. The research investigates how multiple higher-order cortical regions exert top-down feedback onto primary auditory cortex to modulate context-dependent auditory perception. The work develops a novel platform enabling rapid, trial-wise silencing of nine distinct higher-order cortical regions within a single recording session, paired with extracellular electrophysiology and population-level neural analyses. Aim 1 establishes how each feedback source modulates frequency tuning and reorganizes auditory-cortical population activity during passive listening in mice. Aim 2 determines how behavioral engagement reconfigures these distributed networks and how higher-order regions contribute to active transformation of auditory cortex responses when task demands change; mice perform a short-term working-memory auditory categorization task while individual feedback pathways are transiently inactivated during defined behavioral epochs. By comparing the same neural populations across passive listening and active task performance, the research quantifies how feedback pathways shape context-dependent reorganization of sensory representations. The award is a Project Grant assistance type with performance at Carnegie Mellon's Office of Sponsored Programs in Pittsburgh, Pennsylvania. The period of performance runs from January 16, 2027, through August 31, 2029.
