Dr. Avinash Bala, Research Associate at the University of Oregon and Founder of Perceptivo, noticed something about the way owls responded to unexpected stimuli. The owl's pupil noticeably dilates each time it detects an unexpected sound. By studying this pupil dilation response, which is part of the Orienting Response, Bala and colleagues have discovered ways to apply this response toward the creation of a novel and non-invasive hearing test for infants
