Join us for EARssentials 2022, to be held online July 18-22! EARssentials provides students with an overall conceptual view of the auditory system as well as exposure to laboratory techniques unique to research on the inner ear. In the ninth year of this free, week-long course, hosted and taught primarily by scientists at the National Institute on Deafness and Other Communication Disorders (NIDCD), part of the National Institutes of Health (NIH), all sessions will be conducted virtually. Live captioning will be available. Limited in-person attendance (RSVP required) is available for those at NIH.

The primary audience for this course is new intramural NIDCD trainees at all levels. Attendees from other institutions are welcome to attend virtually in 2022. The course is also useful for others who want to learn about concepts related to the auditory system.

This year, we will try a new format with introductory mini-lectures in the morning and live virtual lunchtime discussions (Eastern time) with course faculty. Participants who would like more in-depth information can individually watch archived lectures from the 2016 EARssentials course, either in advance to inform the live discussions or following the course. There will not be a hands-on laboratory component in 2022, but there will be a virtual mouse genetics lab and a workshop on the gEAR (gene Expression Analysis Resource) portal. The week will end with a live panel that explores current treatments for hearing loss and the careers of some of the clinician-scientists at the NIDCD.

If you would like to participate in this year’s virtual EARssentials course, please e-mail Karen Fischer before July 10 to register.
