Putative head-centric flow region in one subject. Signal time courses and anatomical location of a contiguous region of voxels (pHFR) in subject 2 that responded stronger in the opponent conditions (blue) than in the consistent conditions (green). Time courses of the BOLD signal (error bars indicate ±1 SEM) are aligned with the onset of the motion stimulus. The rotational flow component on the retina was either ω = 4°/s (thin-dark) or ω = 8°/s (thick-bright). All activity displayed on the inflated brain and the axial slice has met a minimum statistical criterion of p < 0.05 (see Materials and Methods). Note correspondence with pursuit-modulated anteromedial subregion in Figure 3 (yellow) in this subject.
