Volume 1 contains a historical background and addresses basic coding process, an account of basic psychophysical procedures and principles of sensory coding, and an account of basic mechanisms underlying visual depth perception. It starts with a review of the history of investigations of visual depth perception from the ancient Greeks to the early 20th century. Depth-detection mechanisms in senses other than vision were not investigated before the 19th century. Special attention is devoted to the discovery of the principles of perspective in 15th century Florence, and the discovery of the principles of stereoscopic vision. The chapter ends with a review of early visual display systems, such as panoramas and peepshows, and the discovery and development of stereoscopes and stereophotography.
One chapter reviews the psychophysical and analytic procedures used in behavioural investigations of depth perception. Another chapter deals with the broad topic of sensory coding, including the geometry of visual space, mechanisms of attention, and experience-dependent plasticity of visual functions. A review of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centres.
This is followed by a review of the early evolution of visual systems and of the development of the mammalian visual system in the embryo and post-natal period, with an emphasis on mechanisms of neural plasticity. The development of perceptual functions, especially depth perception, in human infants is then reviewed. These chapters provide a foundation for a review of the effects of early visual deprivation during the critical period of neural plasticity on the development of the various types of amblyopia and of defects in visual depth perception. Various forms of deprivation are discussed, including dark rearing, binocular and monocular enucleation, strabismus, and eyelid suturing.
Volume 1 ends with reviews of the accommodation mechanism of the human eye and vergence eye movements.
