Remarkable advances have contributed to revolutionizing the study of vertebrate vision. The first step to identifying objects and establishing spatial relationships is the visual transduction cascade, a process that underpins a wide range of ocular diseases and therapies. Toward that, The Visual Transduction Cascade: Basic and Clinical Principles reveals not only how the eye evolved into an organ of vision, but also describes how molecular mechanisms of key molecules (such as transducins, phosphodiesterases, and Cyclic GMP metabolizing enzymes) operate in the phototransduction cascade. In this groundbreaking text, experts also explain mechanisms for sensing radiation outside of the visible wavelengths — a good example of the limitations of the human sensory systems. Comprehensive and penetrating, The Visual Transduction Cascade: Basic and Clinical Principles brings together the developmental, structural, and molecular mechanisms of the visual transduction cascade and is an invaluable text for everyone conducting research in the visual system.
