Document Summary

Cortical organization: research on the physiology of stimuli has been dominated by 2 major themes: 1) Describing the types of stimuli that cause neurons at different levels of the visual system to respond; and 2) describing how neurons in the visual system are organized. The organized visual system: organization plays an important role in achieving the tasks of both processing specific information and combining information to create coherent perceptions. Spatial organization: how different locations in the environment and on the receptors are represented in the brain: the organization in visual space then becomes organization of the eye. When the image is transformed into electrical signals, a new type of organization occurs in the form of. Electrical maps" of the retina in structures higher up in the system. One example of cortical magnification is the relatively large area of visual cortex that is activated by stimulation of the fovea.
