Lecture by researcher Penelope W. C. Jeffers at Audiocampus 

The Audiocampus of the Faculty of Pharmacy had the honor of hosting researcher Penelope W. C. Jeffers, affiliated with the Eaton-Peabody Laboratories and Harvard University, for a lecture for students in the State Diploma Program in Audiology.

During her presentation, the scientist discussed her cutting-edge research on the effects of noise exposure on the auditory system. Her research focuses in particular on a phenomenon that is still poorly understood:cochlear synaptopathy—the loss of connections between the ear’s sensory cells and auditory neurons—which can occur even without visible damage to the hair cells.

One of the striking findings of his research shows that, despite a persistent loss of these connections, the auditory system can recover its neural responses, sometimes even beyond normal levels. This phenomenon suggests the existence of a compensatory or dynamic recovery mechanism, which may be activated depending on the intensity of noise exposure. These findings open up promising avenues for better understanding—and perhaps one day treating—certain noise-induced hearing disorders.

This conference was a highlight for the local scientific community, showcasing the University of Montpellier’s international reputation. It also highlighted the central role of the Audiocampus laboratory in promoting cutting-edge research on hearing health.
