Channel tuning functions from V1 in Experiment 2, averaged across all eight subjects. a, Data from the orientation discrimination condition were shifted so that 0° indicates the cued orientation, positive values indicate channels offset in the cued direction, and negative values indicate channels offset in the uncued direction. b, Comparison of responses in channels offset in the cued direction and the uncued direction when subjects were attending to orientation. c, Comparison of responses in channels offset in the cued direction and the uncued direction when subjects were attending to contrast. d, Difference between corresponding channels tuned 18 to 72° in the cued and uncued directions for both the attend-orientation task (solid line) and attend-contrast task (dashed line). Error bars indicate ±1 SEM across subjects.
