This Project Grant award, funded by the National Institute on Deafness and Other Communication Disorders (NIDCD) under the Research Related to Deafness and Communication Disorders Program (CFDA 93.173), supports research into the cellular diversity of the superior olivary complex (SOC) in the brainstem and its role in sound localization.

The primary awardee, Northeast Ohio Medical University (Neomed), will conduct studies to understand how different types of SOC principal neurons, particularly in the lateral superior olive (LSO), process interaural level differences (ILDs) and interaural time differences (ITDs) for sound localization. The $2,389,168.72 award, with a period of performance from August 1, 2024 to May 31, 2029, will fund experimental and computational modeling approaches to investigate the relationship between LSO neuron properties, ILD/ITD coding, and information organization in the inferior colliculus. Swarthmore College is a sub-awardee, providing expertise in computational modeling of LSO neuron dynamics to support the project.

The research aims to yield fundamental insights into the cellular organization of the SOC and how disruptions, such as from hearing loss, may contribute to communication disorders like central auditory processing disorder.
