This article reviews neuronal correlates of selective visual attention emphasizing neurophysiological studies in nonhuman primates. We discuss the effects of directing attention to spatial locations, nonspatial stimulus features, or visual objects on sensory information processing. Furthermore, we describe multiplicative and nonmultiplicative influences of attention on neuronal tuning curves. Finally, we relate the effects of attention to increases in stimulus contrast, both on a neuronal and behavioral level. We propose that attention creates an integrated saliency map, that is, a topographic representation of relative stimulus strength and behavioral relevance across visual space. © 2009 Elsevier Ltd All rights reserved.
