A significant portion of the work is dedicated to the anatomy and physiology of the primate visual system.
Howard details historical display systems like panoramas, peepshows, and the invention of the stereoscope, which first allowed humans to artificially simulate depth.
Howard provides a comprehensive review of how depth perception matures from the embryonic stage to post-natal life. Perceiving in Depth Volume 1 Basic Mechanisms
A detailed analysis covers how disruptions during these critical periods—such as strabismus (crossed eyes) or monocular deprivation—can lead to permanent defects like amblyopia (lazy eye) or a total loss of stereoscopic vision.
is a foundational work by Ian P. Howard that serves as a definitive technical review of the biological and psychophysical processes allowing humans and animals to navigate a three-dimensional world. A significant portion of the work is dedicated
The volume opens by tracing visual science from the ancient Greeks to the early 20th century, highlighting the evolution of our understanding of perspective and stereoscopic vision.
The text follows the visual signal from the eye through the Lateral Geniculate Nucleus (LGN) to the visual cortex. It pays specific attention to the columnar organization of the cortex, which is specialized for depth-related processing. A detailed analysis covers how disruptions during these
Unlike simpler texts, this volume also provides deep dives into the motor controls of vision, such as accommodation (the eye's ability to focus) and vergence (the simultaneous movement of both eyes to maintain single binocular vision). Development and Neural Plasticity
