Central Disorders of Visual Function

"This chapter addresses aspects of behavior disorders caused by damage to the visual cortex and white matter connections."

"This chapter addresses aspects of behavior disorders caused by damage to the visual cortex and white matter connections. These conditions are often referred to as ‘‘central disorders of vision,'' ‘‘cerebral disorders of vision,'' or ‘‘higher disorders of vision.'' The understanding of these disorders continues to improve with the development of new techniques for measuring visual dysfunction, imaging the behaving brain, rehabilitating visual dysfunction in patients with brain damage, and even creating visual sensations in the blind with prostheses to stimulate visual cortex. Insights into how the brain processes visual signals have altered the classic conceptualization of cerebral visual disorders, even raising questions about the nature of the visual loss produced by damage to primary visual cortex."
