Stimuli for corresponding psychophysical experiments (Wagatsuma et al., 2008) and time-courses of the BO signal υ. (A) Five types of random-block stimuli with an ambiguous DOF at the center of the stimulus. Locations of the CRF and spatial attention in these simulations were identical to those in our previous experiments. (B–F) Time-courses of the BO signals ν for stimulus 1, 2, 3, 4, and 5 (20 simulation trials), respectively. Icons at the right show the location of spatial attention. Black dashed, gray solid, and black solid lines represent the BO signals ν without attention, with spatial attention to the left side, and with attention to the right, respectively. For all five stimuli, compared with the nowhere condition, spatial attention attracted the direction of BO toward the attended location and reduced the onset of the time-course for the BO signal ν.
