We mark Hearing Impaired Day with a lecture on restoring damaged hearing. Helge Rask-Andersen lectures on his research on the subject. The research takes place, among other things, on crocodiles, which have the ability to regenerate hair cells in the ear. What can we learn from studying crocodiles and what research is underway for the future? Helge Rask-Andersen is senior professor in experimental otology, the branch of medicine that deals with the ear and its diseases, at Uppsala University and the Academic Hospital in Uppsala. Arranged in collaboration with HRF Lund. Free entry, no pre-registration required.
