Use cutting-edge techniques to explore how synapses that relay information from the ear are changed by experience, and help us learn how to preserve and restore healthy hearing.
Noise exposure or conductive hearing loss can cause lasting effects like tinnitus or auditory processing disorders by altering synaptic function in the auditory system. The Xu-Friedman lab studies the cellular basis of these changes, focusing on auditory nerve synapses that relay sound information to the brain. Students working in the lab gain hands-on experience in advanced techniques, including patch-clamp electrophysiology, calcium imaging, and immunohistochemistry, as well as basic animal handling and tissue preparation. Specific projects are tailored to student interests, such as examining synaptic changes following noise exposure or ear plugging, using structural and functional analyses.
Students will learn general laboratory skills, including solution preparation and tracking supplies. They will learn how to perform histological procedures using immunohistochemistry, and how to prepare live tissue slices for electrophysiology or calcium imaging. Furthermore, students will become versed in how to work in a lab environment, seeking help from others as well as pushing forward on their own. Students will learn how to analyze results and present them within the lab and, pending significant progress, at local or national scientific meetings as posters or papers.

Once you begin the digital badge series, you will have access to all the necessary activities and instructions. Your mentor has indicated they would like you to also complete the specific preparation activities below. Please reference this when you get to Step 2 of the Preparation Phase.
On top of general coursework in neuroscience that includes the auditory system, students can start with reading important background papers, including three central ones that came from the Xu-Friedman lab. Students should read the papers, at least to get a sense of the goals of the lab We will discuss the methods in lab.
