Eric Knudsen is a professor of neurobiology at Stanford University. He is best known for his discovery, along with Masakazu Konishi, of a brain map of sound location in two dimensions in the barn owl, tyto alba. His work has contributed to the understanding of information processing in the auditory system of the barn owl, the plasticity of the auditory space map in developing and adult barn owls, the influence of auditory and visual experience on the space map, and more recently, mechanisms of attention and learning. He is a recipient of the Lashley Award,[1] the Gruber Prize in Neuroscience,[2] and the Newcomb Cleveland prize [3] and is a member of the National Academy of Sciences.
