ABSTRACT
The ability to represent and manipulate spatial information is crucial for a wide range of perceptual, cognitive, and motor functions, including object recognition, reading, writing, attention, visually-guided reaching, and navigating through the environment. As a consequence, spatial processing has attracted considerable interest among cognitive psychologists, and is one of the most active areas of neurophysiological research. However, many of the most fascinating results have come from cognitive neuropsychological research on spatial deficits.
