This federal Project Grant award of $451,000.00 from the National Institute on Deafness and Other Communication Disorders (NIDCD) under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) will support research at the University of Chicago to investigate sex differences and circadian influences on olfactory behavior and neurophysiology in rats. The research aims to examine how biological factors like sex and environmental cues like time-of-day affect olfactory system function, which could provide insights into cognitive health issues like Alzheimer's disease and dementia that exhibit sex and circadian differences. The award will fund a 2-year project starting on August 1, 2025 to conduct behavioral experiments and neurophysiological recordings to understand the underlying mechanisms driving sex differences in olfactory learning and odor processing across the circadian cycle.
