"Feedback connections are a prominent feature of cortical anatomy and are likely\nto have significant functional role in neural information processing. We present\na neural network model of cortical feedback that successfully simulates\nneurophysiological data associated with attention. In this domain our model can\nbe considered a more detailed, and biologically plausible, implementation of the\nbiased competition model of attention. However, our model is more general as it\ncan also explain a variety of other top-down processes in vision, such as\nfigure/ground segmentation and contextual cueing. This model thus suggests that\na common mechanism, involving cortical feedback pathways, is responsible for a\nrange of phenomena and provides a unified account of currently disparate areas\nof research.\n"^^ .
