19 sty 2012 · The retinas are the initial organs for all effects of light on the human visual system. They project to the lateral geniculate body, the superior colliculus, and the suprachiasmatic nucleus (Fig. 2–1).

- Introduction
Beyond vision science, these findings have broad implications. Progress in areas such as neurological/ophthalmological care, robotics, computer vision, and visual display development crucially depends on a fundamental understanding of the human visual system.
Put simply, vision happens like so: the human eye absorbs light from its surroundings and collects it on the cornea. This results in an initial visual impression. Then, each eye forwards this image to the brain via the optic nerve and processes it, resulting in what we call “vision.”
17 sie 2015 · This book provides the essential facts about how visual information is processed in the brain. The book has 16 chapters. Chapter 1 provides basic information about the methods that are used by investigators to find out how visual information is processed in living organisms.
The expanding capabilities and scope of imaging technologies and continued multidisciplinary approach to imaging the eye and brain promises to further broaden our knowledge of the entire visual system: from the anterior eye, to the retina and the cerebral cortex.
The visual system includes the eye and retina, the optic nerves, and the visual pathways within the brain, where multiple visual centers process information about different aspects (shape and form, color, motion) of visual stimuli.
6.1.1 Describe the region of the electromagnetic spectrum that is perceived by our visual system, and the relative energy of photons at long and short wavelengths. 6.1.2 Describe the major parts of the eye and their role in focusing light to create a clear image. In this section, we will meet the range of the electromagnetic energy spectrum ...
