ABSTRACT
This chapter considers the route a photon of light takes to become a known signal in the human brain, indicating how information is extracted from the visual data that creates a specific belief. The visual pathway in a human splits the right and left sides of the two retinas to the right and left halves of the brain in an area called the primary visual cortex. This is vitally important for stereoscopic vision in particular as an object focused on the two retinas found in two places right next to each other, visible as columns. Paradata extend the concept of metadata to consider issues of choice and alternatives as well as subjective decisions. This is an interpretive issue facing archaeologists and an issue relevant to scientists and those working in many other fields. Many new constructs may be used in the creation of paradata and metadata, but one of the costs is the learning and integration times for users.
