Document Summary
Organization plays a central role in achieving the tasks of both processing specific information and combining information to create coherent perceptions. Spatial organization environment are represented by activity at specific locations in the nervous system. refers to the way stimuli at specific locations in the. These examples show that locations on the cortex correspond to locations on the retina. This electronic map of the retina on the cortex is called a retinotopic map . This apportioning to the small fovea of a large area on the cortex is called cortical magnification. The basic principle behind the pet scan is that the parts of the brain that are active will require more fuel from the blood than other, less active parts of the brain. Thus, changes in the activity of the brain are accompanied by changes in blood flow, so monitoring the radioactivity of the injected tracer provides a measure of brain activity.
