	maps, called the early representation. (2) There exists a selective
	mapping from the early topographic representation into a more central

	representation contains the properties of only a single location
	in the visual scene, the selected location. We suggest that this
	mapping is the principal expression of early selective visual attention.
	One function of selective attention is to fuse information from different
	maps into one coherent whole. (3) Certain selection rules determine
	which locations will be mapped into the central representation. The
	major rule, using the conspicuity of locations in the early representation,
	is implemented using a so-called Winner-Take-All network. Inhibiting
	the selected location in this network causes an automatic shift towards
	the next most conspicious location. Additional rules are proximity
	and similarity preferences. We discuss how these rules can be implemented
	in neuron-like networks and suggest a possible role for the extensive
	back-projection from the visual cortex to the LGN.},
