Regions associated with stronger sustained activation for maintaining specified rules than voluntary rules during delay periods
| Region | t value | MNI coordinates | ||
|---|---|---|---|---|
| x | y | z | ||
| Middle orbitofrontal cortex | 5.97 | 0 | 47 | −11 |
| Middle frontal gyrus | 5.36 | −24 | 35 | 43 |
| Ventral intraparietal sulcus | 6.05 | −39 | −79 | 34 |
| Precuneus | 4.98 | −6 | −55 | 28 |
| Middle cingulated gyrus | 4.78 | −3 | −43 | 43 |
| Calcarine sulcus | 4.86 | −6 | −55 | 7 |
Values are statistics (p < 0.05, FWE corrected) and peak coordinates (separated by ≥8 mm) reported in MNI space (mm). The reverse contrast showed no significant activations.
