Areas of the brain that are considered part of auditory cortex in a hearing person are still present in deaf individuals. Which functions these areas of cortex can perform in a deaf person, and which they cannot, may help us to understand the limits of plasticity in these tissues. Chapter 1 reviews the literature on neurological and behavioral changes in the deaf as it pertains to visual processing.
