Concussions are diffuse brain injuries that affect multiple organ systems, including sensory systems in the brain. In this course, Dr. Kraus will show that the auditory system is a common, but underappreciated, locus of disruption following a concussion.
Please note: A handout of the PowerPoint slides is not available for this course.

Nina Kraus, Ph.D., is a scientist, inventor, and amateur musician who studies the biology of auditory learning. She began her career measuring responses from single auditory neurons and was one of the first to show that the adult nervous system has the potential for reorganization following learning; these insights in basic biology galvanized her to investigate auditory learning in humans.
Through a series of innovative studies involving thousands of research participants from birth to age 90, her research has found that our lives in sound, for better (musicians, bilinguals) or worse (language disorders, concussion, aging, hearing loss), shape auditory processing. She continues to conduct parallel experiments in animal models to elucidate the mechanisms underlying these phenomena.
Never having accepted a lack of technology as a roadblock to scientific discovery, Kraus has invented new ways to measure the biology of sound processing in humans that provide unprecedented precision and granularity in indexing brain function. With her technological innovations she is now pushing science beyond the traditional laboratory by conducting studies in schools, community centers, and clinics.
Using the principles of neuroscience to improve human communication, she advocates for best practices in education, health, and social policy.
