Figure 2.

A, t test reveals voxels that were statistically significant (−3.0 > z > 3.0, multiple-comparison corrected, see Materials and Methods) when contrasting tested items at Initial Study with tested items at Final Study. Regions in blue showed greater activity at Initial Study than Final Study, whereas regions in orange showed greater activity at Final Study than Initial Study. Dotted yellow circles indicate regions of overlap in C. B, ANOVA reveals voxels that were statistically significantly different when comparing tested items, restudied items, and neither tested nor restudied items at Final Study (z > 3.0). Dotted yellow circles indicate regions of overlap in C. C, In yellow are five regions defined from voxels that appeared in both of the above contrasts. All data are shown on inflated cortical surface renderings using Caret software (Van Essen et al., 2001).
