Hugh Knowles Professor of Neurobiology & Physiology, Northwestern University

Nina Kraus studies the biology of auditory learning. She has found that experience shapes the hearing brain over time for better (such as through music training) or worse (such as through socioeconomic impoverishment). These brain changes have salient impacts on learning and communication. Kraus' work is rooted in translational  issues, working to bring scientific understanding and new technologies into educational and clinical settings.

BREAKING THE WALL TO NEUROEDUCATION. How the Neuroscience of Sound, Language and Music Shapes Human Communication

Communication through sound is an everyday miracle. Spoken language reaches the listener’s ear as sound waves that our auditory system transforms into brainwaves. But merely decoding sound from the environment is insufficient to guarantee that its meaning will be understood. To make sense of the incoming sound, our brain must learn and adapt over time. This learning process shapes how the brain connects sound with meaning, and is crucial for children – the growing brain needs to process a multitude of different sounds at any given moment, it needs to tell meaning from noise, and register meaningful speech sounds for later use. Connecting sound to meaning is one of the most demanding computational tasks our brain has to master, and the inability to process sound properly is often connected to problems in learning and reading. Nina Kraus, a neurobiology professor at Northwestern University, studies the biology of auditory processing and how the brain’s plasticity allows it to adapt and learn over time. Through a series of innovative studies, Nina and her team have found that our “life in sound” shapes our auditory brain – and that musical training can improve communication and reading skills – throughout the life span. Based on their research, her lab has created a test that predicts children’s literacy skills long before they start reading. This groundbreaking technology allows children at risk of learning disabilities to be identified, making it possible to enrich their life in sound at a very early stage. At Falling Walls, Nina shows how our knowledge of the brain’s potential to change can be used to improve education and communication.
