Smooth Pursuit and Spatial Attention
Various lines of research suggests a tight coupling for closed loop pursuit and spatial attention. For instance, during the close loop phase selective attention is coupled to the pursuit target such that untracked targets which move in the same direction with the target are poorly processed by the visual system. Recently, a loose coupling of open loop pursuit and attention was suggested, when there is only one possible moving target. This difference between pursuit and saccades may be accounted for by the differences in latency. Pursuit eye movements are initiated within 90-150 ms, while typical latencies for voluntary saccades are in the order of 200-250 ms

Famous quotes containing the words smooth, pursuit and/or attention:
“From Rumor’s tongues
They bring smooth comforts false, worse than true wrongs.”

“We should be careful never to imagine, that the wedding-day is the burial of love, but that in reality love then begins its best life; and if we set out upon that principle, and are mindful to keep it up, and give due attention and aid to the progress of love thus brought into the well ordered well sheltered garden, we may enjoy I believe as much happiness as is consistent with the imperfection of our present state of being.”
—James Boswell (1740–1795)
