Table 1. Peak stereotactic coordinates for the main effects of switching (switch trials > non-switch trials).

Coordinates (MNI) of those regions with greater activity during switch trials are listed in the upper portion of the table, while those with greater activity during non-switch trials are listed in the lower portion. Coordinates are given only for those regions that exhibited significant activity after whole-brain correction for multiple comparisons via False Discovery Rate (FDR) at p < 0.05.
