Abstract
Neuronal responses in the visual cerebral cortex can depend greatly on
which aspect of the scene is the target of attention. Accumulating
evidence suggests that while the early stages of the visual pathway provide
a faithful representation of the retinal image, later stages of processing
in the visual cortex create representations that emphasize the viewer's
current interest. By filtering out irrelevant signals and adding
information about objects whose presence is remembered or inferred, the
cortex creates an edited representation of the visual world that is
dynamically modified to suit the immediate goals of the viewer.
