Research Summary

The Xu-Friedman lab studies the mechanisms and functions of synaptic plasticity, focussing on auditory nerve synapses in the mouse cochlear nucleus as a model system. The lab investigates both activity- and neuromodulator-dependent plasticities, using electrophysiology and calcium imaging in brain slices. In addition, the functional effects of plasticity are being studied by recording from auditory nerve and cochlear nucleus in vivo.
