Research in Dr. Kandler's laboratory focuses on the question of how neuronal circuits are established and modified during brain development and how they change under pathological conditions, for example peripheral hearing loss. Ongoing work in a primary sound localization circuit explores the mechanisms by which neuronal activity regulates the organization and maturation of inhibitory connections and their integration with excitatory networks. Another line of research is investigating how abnormal sensory experience affects synaptic circuits in the auditory midbrain. To this end we apply a variety of physiological (whole-cell patch clamp recordings, 2-P calcium imaging, mapping circuits with photostimulation), anatomical (immunohistochemistry, tracing of neuronal connections), and behavioral (acoustic startle behavior) techniques to normal and genetically altered mice.
Students in Dr. Kandler's laboratory have the opportunity to engage in a variety of research projects addressing the questions listed above. Our laboratory is part of the Auditory Neuroscience Group in the Dept. of Neurobiology providing trainees ample opportunities for crossdisciplinary interactions and collaborations in the field of auditory neuroscience and plasticity.
