Attention modulates the visual field in healthy observers and parietal patients.
Recent attention research suggests that factors other than low-level sensory processes modulate perception across the visual field, with right parieto-temporal cortex playing a critical role in directing visual attention to peripheral events. Here we examine how different degrees of attentional demand at fixation dynamically affect detection of abrupt visual onsets in the periphery. In young healthy subjects, peripheral detection was significantly disrupted bilaterally when there was high att...Expand abstract
