Treisman's feature integration theory has been the most influential model of human attention until recent years. According to Treisman, in a first step to visual processing, several primary visual features (such as color, orientation, and intensity) are processed and represented with separate feature maps that are later integrated in a saliency map that can be accessed in order to direct attention to the most conspicuous areas. It was widely speculated, the saliency map could be located in early visual cortical areas, e.g. the Primary Visual Cortex (V1), however this is controversial.
