Figure 4 .

Effects of spatial versus temporal attentional orienting on alpha activity. A whole-brain t-test revealed differences in alpha response amplitude between conditions (i.e., temporal vs. spatial cueing). This effect was significant in the left lateral occipital cortex (top left; Talairach: −38, −73, 13), right hippocampus (top right; Talairach: 26, −20, −10), and left PCC (bottom right; Talairach: −2, −25, 38) with more robust decreases in alpha activity during spatially compared with temporally cued trials (all P’s < 0.001, corrected). In contrast, a significant cluster in the right dlPFC (bottom left; Talairach: 30, 23, 41) exhibited stronger increases in alpha during temporally cued in contrast to spatially cued trials (P < 0.001, corrected).
