Brain regions identified by analysis of no-target trials
| Brain Region | Side | Center of Mass (mm) X, Y, Z | Brodmann Area(s) | Volume (μl) | |
|---|---|---|---|---|---|
| 1 | Intraparietal sulcus | L | -29.5, -53.9, 40.7 | 40, 7 | 391 |
| 2 | Superior/inferior parietal lobule | L | -33.6, -51.4, 51.4 | 40, 7 | 1003 |
| 3 | Inferior parietal lobule | L | -42.7, -35.4, 39.6 | 40 | 383 |
| 4 | Precuneus | B | 1.3, -61.9, 46.3 | 7 | 3027 |
| 5 | Middle frontal gyrus, superior frontal sulcus | L | -24.0, -1.6, 50.9 | 6 | 1498 |
| 6 | Middle frontal gyrus, superior frontal sulcus | R | 22.3, -4, 48.7 | 6 | 281 |
| 7 | Middle frontal gyrus | L | -38.1, 23.6, 35.6 | 9 | 387 |
| 8 | Middle/inferior occipital gyrus | L | -31.2, -87.4, 3.6 | 18 | 1546 |
| 9 | Middle/inferior occipital gyrus | R | 26.8, -90.6, -3.7 | 18 | 490 |
In all regions, the BOLD signal displayed a linear increase as the number of cued locations decreased, i.e. as spatial cueing became more precise, in trials where the cue was not followed by a target. L = left, R = right, B = bilateral.
