Integration of goal- and stimulus-related visual signals revealed by damage to human parietal cortex.

Journal article

Where we look is determined both by our current intentions and by the tendency of visually salient items to "catch our eye." After damage to parietal cortex, the normal process of directing attention is often profoundly impaired. Here, we tracked parietal patients' eye movements during visual search to separately map impairments in goal-directed orienting to targets versus stimulus-driven gaze shifts to salient but task-irrelevant probes. Deficits in these two distinct types of attentional se...
