Model of visuospatial attention. A new model of visuospatial attention control is proposed, in which a number of topographically organized areas in frontoparietal cortex bias attention to the contralateral visual field. Arrows toward the RVF or LVF denote the direction of attentional bias for each lobe (frontal cortex or PPC), while the thickness of each arrow refers to the strength of the attentional bias, or attentional weight. For example, left FEF and PreCC/IFS together exert a stronger contralateral bias toward the RVF than their RH counterparts exert toward the LVF. Gray nodes correspond to topographically organized areas within the RH, while black nodes correspond to those in the LH. Shaded nodes are located in frontal cortex, while nonshaded nodes are located in PPC.
