Figure 2.

Strongly remembered minus classify, poorly remembered minus classify, and poorly minus strongly remembered contrasts. Regions with significant BOLD signal differences (p < 0.01) between strongly remembered and classify trials (A), poorly remembered and classify trials (B), and poorly and strongly remembered trials (C). Positive activity differences are displayed in warm colors and negative activity differences are displayed in cool colors. Subtraction maps are overlaid on every five axial slices of an average anatomical image of all subjects. As depicted in Figure 5A, these activation differences are expected to represent processing related to search, retrieval and post-retrieval processing (A,C), or search only (B).
