MEEI Receives NIH Grant for Measuring and Modeling the Cochlear Motions that Drive the Inner and Outer Hair Cells and Produce Otoacoustic Emissions

Massachusetts Eye and Ear Infirmary Received a 2022 NIH Grant for $117,133 for Measuring and Modeling the Cochlear Motions that Drive the Inner and Outer Hair Cells and Produce Otoacoustic Emissions. The principal investigator is Sunil Puria. Below is a summary of the proposed work. Our knowledge of cochlear mechanics is currently undergoing a revolution. While the basilar membrane (BM) has long been considered the principal structure in cochlear motion, new techniques such as optical coherence tomography (OCT) have instead revealed not only that the reticular lamina (RL) moves in a different pattern from the BM, but that it ...
